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 a great sound that stands up to all of the other overdrives. Read more about it over at RunOffGroove.com

Well worth the effort, build it yourself! I’ve created a public project at OSH Park. Order boards and follow the build docs.

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 the Tube Sound Fuzz, and Way Huge Fat Sandwich. Here’s a link to Charlie’s article read it for yourself: Tube Steak Fuzz.

The IC Big Muff also called the op-amp Big Muff was a version of the Big Muff that used two op-amps in place of the four transistors used in the classic Big Muff Design. Here is a link to more information in the op-amp Big Muff.

The Woolly Mammoth is a PCB design that I made as a clone of the ZVex Woolly Mammoth. I really like the sound of this one. Designed as a fuzz for bass, it sounds good with guitar also. The design is based on the Fuzz Face.
