From the post
Got a request for this one. The Zendrive is a low-to-medium gain overdrive, delivering blues to jazz tones. It has an interesting clipping section, using a combination of diodes and MOSFETs in an asymmetrical arrangement. I've drawn the layout to accommodate board mounted pots (from the solder-side) and it will fit easily in a 1590b.
