These are PCB's I designed up for a DIY pedal. It's based off a schematic I found online. If your into building stuff and would like to use one, I have 8 of them. For $5 I'll mail one to you with a copy of the schematic. If you want tracking, figure $7. I'm currently designing one with a high pass filter, but no ETA as to when it'll be done. Just figured I'd throw these out there if anyone was interested. They measure 52mmx98mm
