I just built this tonight. I really dig the sound. But I accidentally swapped the volume and sustain pots, so it’s quiet with some insane wooly fuzz when dimed. I love happy mistakes.
Thanks for making such great layouts!

hi any chance of anyone building a distortion along the lines of an mxr dd11 dimebag style pedal…for massive gain and crunch…
it would be a brilliant project…

Holy smokes, that’s tiny!!
I fixed a friend’s op-amp BMP years ago and the circuit took up the entire case. Those things were like 6″ x 7″ or so…
Nice work!

Had a bit of trouble finding the out as it isn’t marked or noted in the schematic or pdf. I went to the original site (Paul Nelson) and he had it marked hehehe
Thanks for the layout!
