Here is another 22/7 build. It’s a Big Muff variation. This unique circuit replaces the transistor stages of the classic Big Muff with CMOS inverters. It’s a unique flavor of Muff. CMOS inverters have their own unique flavor of distortion…
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…
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…
This is the second version of the UBE Screamer board. This version fixes a mistake with the reverse polarity diode. I’m calling this ready for public consumption and will add it to the OSH Park projects pages soon. The enclosure…
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…
