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 from a PCB I designed. The board is project on OSH Park. Check out the build Docs below. I used a black powder coat enclosure from Tayda electronics a red anodized dress nut and red anodized aluminum knobs from Lovemyswitches. I used the desktop mill to engrave the labels and logo through the powder coat.

Build your own!
