FSH-1 PCB

This will be the fourth time I try to build one of these. I made a PCB for the original using the layout from GGG. I never finished this. Then I built and finished a second using the layout from UStomp.com. I couldn’t get this to work. I forget what the problems were, it was more than a few years ago. Franciso Pena, of Tonepad.com came up with a new and improved version that used 13600 in place of the 3080s. I built the first version of this. It was the most successful of the bunch. It worked pretty well but had two problems that I couldn’t seem to solve. With mine you could hear a ticking from the sample rate oscillator and the sweep switch refused to work in one direction.

Anyway, I found a sheet of PnP that I had printed sometime ago of Francisco’s second version of the FSH-1. I thought what the heck, might as well give it another try.

    How did your FSH-1 work out this time around? Using Moogerfoogers for random sample & hold, I find using a 4 pole low pass filter produces a lot of ticking, while a 2 pole filter does not at all. Does the FSH-1 use a low-pass or band-pass filter?
