Finishing up & Troubleshooting
1. Test the pedal to make sure it works. Full turn counter clockwise on the rotary switch
is the compressor and should produce a red light. Full turn clockwise is the Compressor
into the ringer and should produce a blue light. Center position on the rotray switch is the
ringer and should produce a green light
2. Bias the compressor by by ear by adjusting the trimpot. You want to turn your amp
down low and strum hard. Continue strumming hard while turning the trimpot with a very
small screwdriver untill you get a good clean tone with minimal distortion, good volume
boost, and noticeable compression. Note that the compressor will produce a small
amount of distortion even when it is biased properly.
3. Test the toggle switch. The toggle switch only affects the compressor portion of the
circuit, so you should test your toggle switch with the red light on. Center position is
fast attack . To the left is slow attack and to the right is medium attack .
4. Put the cover on and screw it down
5. Apply the rubber feet.
Is you pedal working? Here s a few common mistakes:
1. No sound at all in either the bypass or on position. If you aren t getting sound in
bypass then you did not wire your footswitch correctly. Getting the bypass to work is the
first thing you need to worry about
2. Bypass works and the LED lights up when on , but there s no sound. You either
have a problem with the wiring from the in to the out of the circuit board and foot switch.
The green wire is the in and the brown wire is the out. Or you have a problem with
something on the circuit board
3. Bypass works, but there s sound when on and the LED does not come on . You
probably aren t getting any power to the circuit. Check all the black and red wires
4. Everything works, but the boost is weak. You ve probably got your transistor in
backwards
5. The volume completely cuts out when I turn the knob all the way counter
clockwise. It s supposed to do that
If none of this helps, and you can t seem to figure out the problem, I always find that it is
best to just set the pedal aside for a day or 2 and then come back to it with a fresh pair of
eyes. Then the problem usually jumps right out at you .usually.
If you still can t get it working, start a thread on the BYOC forum and ask for help.
