I got three boards from Pedal PCB. This is a pretty good project. It cost a bit more than the usual 1590B sized projects. It works well and sounds great. I’m keeping one and selling the other two on Reverb…

Built and test this second version of the 22/7 by RunOffGroove.com. Sounds good. This is a great alternative for Big Muff fans. The OSHPark project is public and verified. 22/7 is a Big Muff built around CMOS inverters in place…
