The life of these batteries may be limited, however, since their primary purpose was to enable testing. Insert the included batteries as shown in figure, being careful to orient the batteries correctly. fig.0010 Making the Connections The ME-50B is not equipped with any internal amplifier or speakers. To listen to sound with the ME-50B, connect it to a bass amp, stereo headphones, or other such sound equipment. * To prevent malfunction and/or damage to speakers or other devices, always turn down the volume, and turn off the power on all devices before making any connections. fig.0020 Bass Guitar Stereo Headphones AC Adaptor (PSA series: optional) CD/MD Player, etc. · When turning the unit upside-down, get a bunch of newspapers or magazines, and place them under the four corners or at both ends to prevent damage to the buttons and controls. Also, you should try to orient the unit so no buttons or controls get damaged. · When turning the unit upside-down, handle with care to avoid dropping it, or allowing it to fall or tip over. · Make sure the "+" and "-" ends of the batteries are oriented correctly. · A "b" appears in the display when the batteries are nearly worn out. When this occurs, replace with new batteries. · When replacing the batteries, use six AA type. · Avoid using new batteries together with used ones. In addition, avoid mixing different types of batteries. Doing so can result in fluid leakage. · Battery life can vary depending on battery type. Bass Amp If there are batteries in the unit while an AC adaptor is being used, normal operation will continue should the line voltage be interrupted (power blackout or power cord disconnection from the ME-50B). To prevent the inadvertent disruption of power to your unit (should the plug be pulled out accidentally), and to avoid applying undue stress to the AC adaptor jack, anchor the power cord using the cord hook, as shown in the illustration. fig.0040 Continuous usage time under battery power is about 12 hours with alkaline batteries and about 3.5 hours with carbon batteries. (This may vary according to usage conditions.) When outputting monaurally, connect a cable only to the OUTPUT L (MONO) jack. Do not use a cable containing a resistor to connect CD or MD players to the AUX IN jack. If a cable incorporating resistance is used, audio from CD and MD players may become inaudible. 6 Playing Sounds Turning on the Power Once the connections have been completed, turn on power to your various devices in the order specified. By turning on devices in the wrong order, you risk causing malfunction and/or damage to speakers and other devices. * If using the ME-50B with a CD or MD player, be sure to turn on the power to the connected device first. 1. ME-50B fig.0041 If There Is No Sound/If the Volume is Low Are connections to other devices correctly made? Check the connections once more. Is the volume turned down? Check the volume levels on any connected amp or mixer. Can you hear sound through the headphones when headphones are connected? If you can hear sounds, it may be that there is a short in the cable used to connect the amp or other device, or perhaps a mistake in an external device's settings. Check the connecting cables and external devices once more. Has the level been lowered with the expression pedal? Sounds are not output when the toe of the expression pedal is in the raised position while the pedal is set to function as a volume pedal (p. 18). Is the ME-50B in Tuner mode (p. 25)? In Tuner mode, the bypass sound is output, and the expression pedal is used as a volume pedal. When the expression pedal is used as a volume pedal, sound output falls as you pull the pedal back, raising the front of the pedal (p. 18). Is a cable containing a resistor being used to connect a CD or MD player to the AUX IN jack? Using a cable containing a resistor may prevent sound from CD and MD players from being audible. 2. Bass Amp /Stereo, Multitrack Recorder, Etc. * Turn up the volume on amps and other equipment only after all connections are completed and the power for connected devices is turned on. * This unit is equipped with a protection circuit. A brief interval (several seconds) after power up is required before the unit will operate normally. Adjusting the Volume Adjust the ME-50B's volume with the MASTER LEVEL knob. fig.0050 Turning Off the Power * Raising the MASTER LEVEL knob too much may result in sound distortion. * When the effects are all off, input and output are at the same levels as when the MASTER LEVEL knob is at the center position. * The setting of the MASTER LEVEL knob is stored in memory for each patch (p. 21). 1. Turn down the volume of the ME-50B and any connected device. 2. Turn off the power to Bass Amp / Stereo, Multitrack Recorder, etc. 3. Turn the ME-50B's power off. 7 Using the Effects When the power is turned on, the FILTER/TONE, DRIVE/SYNTH, and DELAY/MODULATION are switched off. Also, the expression pedal will function as volume pedal. * When the DELAY/MODULATION TYPE is set to HOLD DLY, the DELAY/MODULATION indicator goes on, the DELAY/MOD pedal's indicator flashes at a fixed interval, indicating recording standby is enabled. (p. 16) All product names mentioned in this document are trademarks or registered trademarks of their respective owners. Those companies are not affiliated with BOSS and have not licensed or authorized BOSS's ME-50B. Their marks are used solely to identify the equipment whose sound is simulated by BOSS's ME-50B. About the Effect Connection Sequence The ME-50B automatically selects the optimum sequence for connecting the effects according to the effect settings. fig.0060 DRIVE/SYNTH = SYNTH +1 OCTAVE / DRIVE/SYNTH = Others -1 OCTAVE (EXPRESSION) NATURAL / BASS DRIVER / OVER DRIVE / DISTORTION / MUFF FUZZ / METAL / HI-BAND DRIVE (DRIVE / SYNTH) SAW LEAD / MILD FILTER / DEEP FILTER / SQUARE (DRIVE / SYNTH) OCTAVE UP / SLOW GEAR / DEFRETTER / ENHANCER / BOTTOM BOOST / MID SHAPE / HOLLOW (FILTER / TONE) COMPRESSOR / LIMITER OCTAVE DOWN T.WAH UP / T.WAH DOWN / T.WAH EDGE (FILTER / TONE) WAH / RESONANCE (FILTER / TONE) (EXPRESSION) EQ NOISE SUPPRESSOR FOOT VOLUME SOUND HOLD DELAY / MODULATION LEVEL (MASTER) (EXPRESSION) (MASTER) DELAY/MOD = HOLD DLY KICK DRUM (EXPRESSION) DELAY/MOD = Others 8 Using the Effects COMPRESSOR/LIMITER fig.0110 COMPRESSOR/LIMITER indicator THRESHOLD/SUSTAIN knob Adjusts the depth of the effect. When the TYPE is set to NATURAL, LIMITER, 160D SOFT, or 160D HARD, this functions as the THRESHOLD knob, which sets the level at which the limiter starts to take effect. The more the knob is turned to the left (counterclockwise), the lower the level at which the limiter effect is enabled. This comprises two effects, one that evens out the volume of the input signals to provide lengthy sustain (compressor), and one that prevents distortion by suppressing only the peaks in the sound (limiter). When the TYPE is set to D-COMP, the knob functions as a SUSTAIN control, which adjusts how long sounds are sustained. Turn the knob to the right (clockwise) to get longer sustain times. TYPE knob OFF Turns off the compressor/limiter effect sound is bypassed. * The COMPRESSOR/LIMITER indicator goes off when this is set to OFF. LEVEL knob This adjusts the level when the compressor/limiter is on. Use this to balance the volume level so it is the same when the compressor/limiter is switched on and off. NATURAL Provides natural-sounding performances with little thinning of the sound, even when pushing the effect. This is especially effective with slapping and hard picking. You can use a foot switch to switch the compressor/ limiter on and off. For more detailed information, refer to "Using the Foot Switch" (p. 26). LIMITER Prevents distortion by suppressing the input signal level when it exceeds the set value. 160D SOFT Models the dbx 160 set to a lower compression ratio. 160D HARD Models the dbx 160 set to a high compression ratio. D-COMP Models the MXR DynaComp. 9 Using the Effects FILTER/TONE fig.0120 FILTER / TONE indicator T.WAH EDGE: Gives a filter with a stronger effect. SENS/BOTTOM knob Adjusts the sensitivity when the filter is being altered. DEPTH/TONE knob Adjusts the reference frequency for the wah effect. RESONANCE/E.LEVEL knob Adjusts the amount of wah effect at frequencies near the reference frequency. Turning the knob to the left widens the range of frequencies in the vicinity of the reference frequency in which the wah effect is to be produced, while turning the knob to the right narrows this range. Pedal indicator OCTAVE UP/OCTAVE DOWN This effect creates a fatter, thicker sound by adding to the input sound the same sound raised one octave (OCTAVE UP) or lower one octave (OCTAVE DOWN). * This effect does not function correctly if two or more notes are played simultaneously. FILTER / TONE pedal SENS/BOTTOM knob Adjusts the volume of the direct sound. Included here are eleven different effects that alter the particular characteristics of the bass sound itself. You can select and use any one of these effects at a time. DEPTH/TONE knob Adjusts the tone of the octave sound. Turn the knob to the left for a milder sound or to the right for a sharper sound. FILTER/TONE pedal The filter tone is alternately switched on and off each time you press the pedal. The indicator lights up when the effect is on. RESONANCE/E.LEVEL knob Adjusts the volume of the octave sound. SLOW GEAR This produces a volume-swell effect (similar to how a violin is played. TYPE knob Selects the effect to be used from the eleven different effects that are available. SENS/BOTTOM knob Adjusts the sensitivity of the slow gear effect. As the knob is turned more to the left, there is less response to weaker picking, so the effect is expressed only when strong picking is used. T.WAH UP/T.WAH DOWN/T.WAH EDGE This effect alters the wah effect in response to the level at the time the bass is played. DEPTH/TONE knob This adjusts the time needed for the volume to reach its maximum from the moment you begin picking. T.WAH UP: The filter shifts to higher frequencies in response to the input. RESONANCE/E.LEVEL knob Adjusts the volume of the effect sound. T.WAH DOWN: The filter shifts to lower frequencies in response to the input. 10 Using the Effects DEFRETTER This effect allows you to use a conventional bass to simulate a fretless bass. SENS/BOTTOM knob Adjusts the amount of defretter effect applied in response to the input sound. DEPTH/TONE knob Adjusts the tone. Turn the knob to the left for a milder sound, or to the right for a sharper sound. RESONANCE/E.LEVEL knob Adjusts the volume of the defretter sound. ENHANCER This is an effect that clarifies the contour of the input sound by emphasizing the sound following changes in the input level. SENS/BOTTOM knob This adjusts the Enhancer sensitivity. The more the knob is turned to the right, the more softly you can play and still have the effect applied. DEPTH/TONE knob Adjusts the frequency at which the enhancer will begin to be applied. The effect is applied at higher frequencies the more the knob is turned to the right. RESONANCE/E.LEVEL knob Adjusts the amount of enhanced sound added to the mix. BOTTOM BOOST/MID SHAPE/HOLLOW Alters the special characteristics of the bass sound. BOTTOM BOOST: Creates a tone with a boosted low end. MID SHAPE: Creates a tone with the midrange cut back. HOLLOW: Adds body resonance to create a tone resembling that of an acoustic-electric bass. SENS/BOTTOM knob Adjusts the tone of the lower range. DEPTH/TONE knob Adjusts the tone of the upper range. RESONANCE/E.LEVEL knob Adjusts the volume. 11 Using the Effects DRIVE/SYNTH fig.0130 DRIVE / SYNTH indicator MUFF FUZZ Models the Electro-Harmonix Big Muff . METAL Wild, radical distortion sound. HI-BAND DRIVE With this effect, distortion is applied only to the highfrequency sounds, and not to the sounds in the lowfrequency range. SAW LEAD A saw-wave synth-bass sound with a slight filter motion. Pedal indicator Using the effect in combination with the Expression (p. 18) type set to "RESONANCE" makes it even more effective. DRIVE / SYNTH pedal MILD FILTER A saw-wave synth-bass sound with relatively weak filter effect. A motion of the filter changes depending on the strength or the position, when playing the bass. This distorts the sound, or create an effect like that of an analog synth. DEEP FILTER A saw-wave synth-bass sound with a strong filter effect. A motion of the filter changes depending on the strength or the position, when playing the bass. DRIVE/SYNTH pedal The DRIVE/SYNTH is alternately switched on and off each time you press the pedal. The indicator lights up when the effect is on. SQUARE A square-wave synth-bass sound. A motion of the filter changes depending on the strength or the position, when playing the bass. * When SYNTH (SAW LEAD­SQUARE) is selected, this effect does not function correctly if two or more notes are played simultaneously. TYPE knob NATURAL Overdrive that gives a more natural sounding distortion. BASS DRIVER Models the TECH21 SANSAMP BASS DRIVER DI. DRIVE/SENS knob When DRIVE (NATURAL­HI-BAND DRIVE) is selected Adjusts the amount of distortion applied. Turning the knob to the right boosts the distortion and increases the volume. OVER DRIVE Models the BOSS ODB-3. DISTORTION Distortion tuned especially for use with basses. When SYNTH (SAW LEAD­SQUARE) is selected Adjusts the amount of filtering applied. 12 Using the Effects TONE/CUTOFF knob When (NATURAL­HI-BAND DRIVE) is selected Adjusts the tone. Turn the knob to the left for a milder sound or to the right for a sharper sound. When SYNTH (SAW LEAD­SQUARE) is selected Adjusts the frequency at which the harmonic components of the sound are cut (the cutoff frequency). D.LEVEL/RESONANCE knob When (NATURAL­HI-BAND DRIVE) is selected Adjusts the volume of the direct sound. * Normally this adjusts the sound immediately ahead of its being input to DRIVE/SYNTH, but when OCTAVE UP is selected as the FILTER/TONE type, this adjusts the sound input to the INPUT jack. Thus, only the sounds raised by an octave are distorted, giving an effect that sounds like a guitar playing in unison with the direct bass sound. When SYNTH (SAW LEAD­SQUARE) is selected Adjusts the amount by which the harmonic components near the cutoff frequency are boosted. E.LEVEL knob Adjusts the volume. * Noise may creep into the sound if the E.LEVEL knob is turned up too high. Adjust the E.LEVEL knob so the volume level sounds the same whether the effect is switched on or off. 13 Using the Effects DELAY/MODULATION fig.0140 DELAY / MODULATION indicator " .TAP DLY" (refer to the following) "Adding a Delay Synchronized to the Performance Tempo" (p. 16) "Adding a Modulation Synchronized to the Performance Tempo" (p. 17) TYPE knob Selects the effect to be used from the eleven different effects that are available. .TAP DLY Pedal indicator This is a tempo delay that lets you set a dotted eighth note delay time for the performance tempo by pressing the DELAY/MOD pedal in time with the performance tempo. * The delay time can be set within the range of 46.5 ms to 1050 ms. DELAY / MODULATION pedal "Using the .TAP DLY Function" (p. 16) This provides the delay effect, in which the sound is slightly delayed and is fed back to the direct sound, and the modulation effect, which adds a sort of swell to the sound to give it greater breadth. The ME-50B comes equipped with eleven different delay and modulation effects. You can select and use any one of these effects at a time. TIME/RATE knob This has no effect or function. FEEDBACK/DEPTH knob Adjusts the amount of feedback (number of repeats). Turning the knob to the right increases the number of times the sound repeats. E.LEVEL/RESONANCE knob Adjusts the volume of the delay sound. DELAY/MOD pedal The Delay/Modulation is switched on or off each time you press the pedal. When switched on, the DELAY/MOD indicator and pedal indicator light up. * When .TAP DLY is selected, holding down the DELAY/ MOD pedal for at least two seconds, causes the effect to turn off. * When HOLD DLY is selected, you cannot switch the effect on/ off by pressing the pedal. * DELAY ON/OFF switches the Delay at the input to provide a more natural effect. For this reason, if the FEEDBACK is turned up when the Delay is turned off, the delay sound will remain briefly. * When a setting other than HOLD DLY, CHO + REVERB, or REVERB is selected, you can use the DELAY/MOD pedal to input the tempo, and set the delay time synchronized to the performance tempo. HOLD DLY Up to 2.8 seconds of performance content is recorded, then played back repeatedly. You can also layer this as you perform something else, then record these together (overdub). You can keep the recorded content playing continuously as backing and produce other special effects. "Using the HOLD DLY Function" (p. 16) TIME/RATE knob This has no effect or function. FEEDBACK/DEPTH knob This has no effect or function. E.LEVEL/RESONANCE knob Adjusts the volume of the playback sound. 14 Using the Effects ANALOG DLY/0-400 ms DLY/300-1400 ms DLY ANALOG DLY: This gives a mild analog delay sound.

The unit goes into recording standby and the pedal's indicator flashes at a fixed interval. * After switching to HOLD DLY, you cannot perform any operation during the 2.8-second period before the unit switches to recording standby. Wait for at least 2.8 seconds before moving on to the next step. 2. Press the DELAY/MOD pedal to start recording. Recording starts when you press the DELAY/MOD pedal. The indicator flashes during recording. 3. Press the DELAY/MOD pedal once again to end recording. Playback of the recorded content begins simultaneously (the indicator remains lit). * The maximum recording time is 2.8 seconds. If the recording time exceeds 2.8 seconds, the recording stops automatically, and the recorded content is then played back. * An oscillating sound may be audible with extremely short recording times. 4. When layering recordings, repeat Steps 2 and 3. * The recorded content is cleared when the TYPE knob is switched to a different setting or when the power is turned off. 5. Adjust the volume. Adjust the volume of the playback sound with the E.LEVEL/RESONANCE knob. 6. When returning to the recording standby, hold down the DELAY/MOD pedal for the same length of time as the recording. The unit returns to recording standby, and the pedal's indicator flashes at a fixed interval. Using the .TAP DLY Function 1. Set the TYPE knob to .TAP DLY. * If the effect is OFF, press the DELAY/MOD pedal to turn it ON. The pedal indicator flashes in time with the current tempo. 2. Press the DELAY/MOD pedal in timing with the tempo more than two times. The reference tempo is determined by the time interval between each press of the pedal. The reference tempo is calculated in terms of quarter notes, and the delay time setting is the dotted eighth note as referenced to the reference tempo. The pedal indicator flashes in time with the tempo. fig.0141 Timing Delay Sound Adding a Delay Synchronized to the Performance Tempo The delay time can be set according to the tempo input when the TYPE is set to ANALOG DLY, 0-400 ms DLY, 300-1400 ms DLY, or CHO+DELAY. The delay time can be set within the range of 62 ms to 1400 ms. You can set this regardless of whether the effect is on or off. 1. Hold down the DELAY/MOD pedal for at least two seconds. · If the DELAY/MOD pedal is pressed when the effect is on, the pedal indicator goes out, and the effect is turned off. · If the DELAY/MOD pedal is pressed when the effect is off, the pedal indicator turns red, and the effect is turned on. When you continue to depress the pedal, after two seconds the pedal's indicator starts to flash, and the tempo can then be set with the effect on. Here, the delay time is indicated by the value set with the TIME/RATE knob. 2. Press the DELAY/MOD pedal in timing with the tempo more than two times. The delay time is set according to the time interval between each press of the pedal. The pedal indicator flashes in time with the tempo. * Press the pedal to set the tempo while no bass sound is playing. You can return to the recording standby immediately by using external foot switch. For more detailed information, refer to "Using the Foot Switch" (p. 26). * When playback is stopped, the recorded content is erased. * To start recording again, wait 2.8 seconds, then carry out step 2. 16 Using the Effects 3. Hold down the pedal switch for at least two seconds to complete the tempo setting. The effect goes on, and instead of flashing, the pedal indicator will light. * The tempo may become confused momentarily when you go from Step 2 to Step 3. * If you move the TIME/RATE knob after finishing this setting, the delay time corresponding to the knob position takes effect. Adding a Modulation Effect Synchronized to the Performance Tempo When the TYPE is set to PHASER/FLANGER/CHORUS, you can set the tempo so you get an effect that is synchronized to the performance tempo. * The allowable rate cycles for the tempo settings range from 62 ms to 2000 ms. 1. Hold down the DELAY/MOD pedal for at least two seconds. · If the DELAY/MOD pedal is pressed when the effect is on, the pedal indicator goes out, and the effect is turned off. · If the DELAY/MOD pedal is pressed when the effect is off, the pedal indicator turns red, and the effect is turned on. When you continue to depress the pedal, after two seconds the pedal's indicator starts to flash, and the tempo can then be set with the effect on. Here, the tempo is indicated by the value set with the TIME/RATE knob. 2. Press the DELAY/MOD pedal in timing with the tempo more than two times. The tempo is set according to the time interval between each press of the pedal. The pedal indicator flashes in time with the tempo. Setting the TIME/RATE near the desired tempo beforehand allows you to make faster and more natural tempo settings. 3. Hold down the DELAY/MOD pedal for at least two seconds to complete the tempo setting. The effect goes on, and instead of flashing, the pedal indicator will light. * If you move the TIME/RATE knob after finishing this setting, the rate corresponding to the knob position takes effect. Executing Write Procedures (p. 22) After the Tempo Has Been Set The delay time stored in a Patch (p. 21) is determined as follows. · If it is within the delay time range that can be set for the type currently selected, it is stored without change. · If it exceeds the maximum delay time that can be set for the type currently selected, the maximum value for the type is stored. · If it is less than the minimum delay time that can be set for the type currently selected, the minimum value for the type is stored. (Example) When TYPE is 0-400 ms When the delay time for the tempo setting is 600 ms: Stored as 400 ms. (Example) When TYPE is 300-1400 ms When the delay time for the tempo setting is 200 ms: Stored as 300 ms. You can use a foot switch to set the DELAY/MODULATION tempo. For more detailed information, refer to "Using the Foot Switch" (p. 26). A Note About the Quantize Function When you set tempo using the DELAY/MOD pedal or start recording in HOLD DLY while the KICK DRUM is playing drum beat, the set tempo or the recording time is adjusted automatically by the tempo of the drum beat. The KICK DRUM sound will also be recorded on the HOLD DLY, so you will not be able to control the KICK DRUM sound with the expression pedal, once you start the playback.) "Using the KICK DRUM Function" (p. 19) 17 Using the Effects Pedal fig.0150 PEDAL MODE indicator WAH The effect will function as a pedal wah. RESONANCE This completely original effect offers enhancements on the characteristic resonances produced by analog synth filters. Using the effect in combination with the DRIVE/SYNTH TYPE set to "SAW LEAD" or "SQUARE" makes them even more effective. You can make the setting that determines whether the ME50B's pedal functions as a volume pedal or as an expression pedal. In addition, when using it as an expression pedal, you can use it to control one of the special pedal effects that you select. +1 OCTAVE Allows the pitch to be raised up to one octave above the original bass sound. * This effect does not function correctly if two or more notes are played simultaneously. Using the Pedal as a Volume Pedal When using the expression pedal as a volume pedal, press the expression pedal all the way forward and then give it a stronger push, the PEDAL MODE indicator goes off. fig.0160 -1 OCTAVE Allows the pitch to be lowered up to one octave below the original bass sound. * This effect does not function correctly if two or more notes are played simultaneously.
