I just got these PCBs in the mail from https://www.pcbway.comPCBWay.com. I’m impressed with the quality. This is an update of my my 22/7 PCB. I made a couple small improvements.
The 22/7 is a CMOS based Big Muff. A very cool and innovative circuit by RunOffGroove.com. Did I mention they just turned 20 years! If you like the Big Muff but would like something a little different try this.
