From the project

A widely known overdrive pedal

This project has a very similar electronics to Ibanez TS-808 TubeScreamer. Moreover this board let you choose among several modifications of the original design, and implement it easily. The most important modification is the ability to build a true bypass or buffered bypass pedal. Also there will be plenty of room for the most usual mods out there:

- Easier to provide "more gain" - Easy to replace Op-Amp - Easy to swap diodes (different distortion sounds) - Easy to swap between flavors TS5, TS10 and TS808
