That Screamer

Overdrive

Tube Screamer-style overdrive with four modes from the TS808, TS9 and TS10, on a JRC4558D.

That Screamer is Formula B's Tube Screamer, built around the original JRC4558D op-amp and offering four selectable character modes inspired by the TS808, TS9 and TS10 across the pedal's history.

Drive, Tone and Level cover creamy, dynamic, touch-sensitive overdrive from light grit to a fuller push, and the mode switch lets one pedal cover several classic screamer voicings. True bypass, running at around 10mA from 9V DC center-negative. Hand-built in Todi, Italy by Marco Bovelli.
