Congratulations
on your purchase of Dual Drive distortion, a warm, creamy, vintagesounding distortion pedal that gives you two channels of glorious
T-Rex gain.
Dual Drive was designed to let your switch from your clean amp
sound, to a nice crunchy overdrive, and on to a sweet, searing distortion you can use for solos or grungy power chords – all in a single
pedal.
At each stage along the way, you’ve got complete control over gain,
tone and level.
To get started, check out the controls overview in this user manual.

Dual Drive Controls
Your Dual Drive has 3 controls for each of the 2 channels:
GAIN, LEVEL and TONE.
The GAIN knob is the most important control on your Dual
Drive. The more you turn it up, the more overdrive gain you get.
The GAIN control for Channel A goes from clean to a moderate
overdrive sound. The GAIN control for Channel B starts where
Channel 1 stops – and takes you all the way up to a creamy distortion. Leave the pedal off to play straight through your amp.
Switch the pedal on to add overdrive crunch. Switch to Channel
B for premium vintage distortion.
The LEVEL knob is used to set the overall output volume from
each channel of your Dual Drive. At 12 o’clock your output is
the same as your input volume. Turning it all the way up (clockwise) will boost your output signal by 15 dB.
The TONE knob lets you control the top end, or “edge”, of your
signal without compromising sonic quality. Try setting it separately for each channel to create your own signature overdrive
and distortion sounds.
