Ah that might be the case. I usually play with some crunch from the amp already. I'll try it completely clean.

Cheers again for this awesome circuit!

You should be able to pick out exactly what it does then, it may be the case that you can just hardwire the diodes on all the time. It depends on what you like!

Oh I heard the difference clearly when I used a clean signal on the amp. I do prefer it with a dirty channel though! How would I bypass the bias knob and just have three knobs?

Depends on what you like. Based on rizibiz vero, if you like it say, full CW, substitute the pot with a 10K resistor; if you like it full CCW, substitute the pot with a jumper; and, if you like something in between, set the pot at your taste, desold it, take measure between lugs 1 and 2, find a resistor with that value (or something closer) and substitute the pot with that resistor.
A best/simpler option? Put a 10K trimmer inside, set and forget.

Cheers! Would I put the resistor on the corner where the two wires from the bias knob go, and how about the wire that goes from the master knob to the bias?

The resistor would go to where the bias pot wires went just take the wires out and solder the resistor to the vero board in their place. The master volume connection (the light blue one) just needs to be soldered to where it originally goes on the board - the output side of the 100nf cap.

i just watched the video demo on youtube and this pedal really sounds interestingly good! i just did a vero layout for myself and i thought i'd share.. though it isn't verified yet! :oops: :lol:
