(1) (6) (2) (3) (5) (7) Introduction Nady's original TD-1 tube overdrive was marketed in the mid 1980's and was one of the earliest tube distortion pedals. The new, updated TD-1 combining classic tube overdrive warmth and tonality with the latest advanced EQ and Tone control options, the TD-1 is capable of delivering almost any sound. Its rich harmonics, unlimited tonal range, and unequalled definition make any amp sound great. · Real tube tone from the classic 12AX7A twin triode tube -- each carefully selected for optimum tonality and absence of noise, microphonics, and other artifacts that can detract from your sound · State-of-the-art 3-stage variable tube drive design for widest range of overdrive options, from mild growl and crunch to singing sustain and controlled feedback · Advanced EQ section carefully designed for all contemporary styles -- blues, jazz, country, R & B, and all types of rock -- with specially tailored high and mid-low 3-stage variable shelving and boosting options, plus a variable presence control for the ultimate tone-shaping possibilities · Compact enough for a pedal board · Rugged 14-gauge steel housing and heavyduty bypass footswitch for years of trouble-free performance (4) (8) (9) (10) (13) Controls and Connections 1) LEVEL The Level control adjusts the overall signal output level. 2) DRIVE The Drive control adjusts the amount of distortion.

HIGH +22dB, MED +10dB, LOW 0dB 4) HIGH This control adjusts the treble frequencies of the signal post distortion. It boosts/cuts by +/- 15dB @ 10KHz from mid position (12:00). 5) HIGH END This switch boosts/cuts the brightness/treble (10KHz) of the tone post distortion. HIGH +5dB, MED 0dB, LOW ­10dB 6) LOW This control adjusts the low/mid tones of the signal post distortion.
