I wondered what that diode was for. I also used a jumper to correct the switching. HP was louder than LP, is that how yours is? I liked HP better, other than that I didn't notice any major tonal differences. I would build another without the switch. It did sound very good at 1-2 o'clock gain setting, past 3 o'clock the sound was more compressed, almost like a light fuzz sound. Very usable.. I gave that pedal to a stoner rock friend of mine and he loves it. I may have to make another one with your corrections, thanks.

yeah thats what i use max, but the sizzle already annoys me when i turn the gain down to 0

thanks!i will give it a shot, maybe i should also try experimenting with diodes with higher forward voltages also, leds for example, instead of the mosfets to get more headroom? the maximum gain is much too much for me also, i prefer stacking lower gain ODs for more distortion.

but they sound so great usually!
