Forgot I had the later and more common version in a folder… For the earlier quad op amp version there is a layout HERE.
This is pretty much a souped up DOD250/MXR Distortion Plus derivate with more gain on tap and useful gain control. But the most interesting thing is the “Sens” control which pand between a low pass filter and hard clipping diodes. Schematic is avaiable HERE.
Per request. The layout stays mostly true to the schematic. One half of the op amps was unused to I used it for buffered Vref which doesn’t hurt. Quite an interesting design if a bit over engineered.:-)
Per request. Schematic is avaiable HERE and a verified layout for the Lead Channel is avaiable HERE.
