UBE Screamer 1.1.1 build

UBE Screamer build

Built and tested the new version of the UBE Screamer PCB. Everything is working! Sounds great. This is a good alternative to the standard TS-808 and other overdrives if you’re looking for something a little different. Does great low gain…

UBE Screamer PCB

This is an update of the UBE Screamer board. Same circuit just revised. I had these boards fabricated at PCBWay.com. The quality is very great! The UBE Screamer is a very interesting take on the Ibanez Tube Screamer by RunOffGroove.com.…

22/7 PCB Order

I just got these PCBs in the mail from 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…

RunOffGroove UBE Screamer

This is another great RunOffGroove project. It’s a unique twist on the classic Ibanez Tube Screamer. The UBE Screamer replaces the op-amps and transistor stages in the Tube Screamer circuit with inverters from a 4049UBE hex inverter. I built this…

22/7 on OSH Park

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…

UBE Screamer by RunOffGroove

This UBE Screamer by RunOffGroove.com is a unique twist on the venerable Ibanez Tube Screamer TS-808. It replaces the op-amps and transistor stages with a single hex inverter using an inverter in place of each op-amp and transistor. This has…

More OSH Park PCBs

These are some more PCBs from OSH Park. There is an IC Big Muff, Tube Steak, and a Woolly Mammoth. The Tube Steak I created from a schematic posted by Charlie Barth at Moosapotamus.net. Tube Steak Fuzz is a cross between…
