This one was in the drawer for a while. An Electro Harmonix Pulsar, the older/original version. It didn't work right when I first put it together, so off to the side it went. Pulled this and a couple others out recently and got them all working.
A friend gave me the pcb, but it was made @ Pigeon FX. The layout used, along with more info on tweaks, fixes, etc can be found at Tonepad. I highly recommend swapping the listed rate control value of a100k with b10k. It will fix the sweep issues.
I'm still working on my etching (as if you couldn't tell). The extra switch will momentarily change to a square wave shape as long as it's held down.
