Specimen 637

Badder Monkey

An overdrive built around three switchable circuits — Behaved, Bad and Badder — with parallel blending, so one pedal covers several gain stages.

Watch

The Jam Shed's clip is a short play-through of the Badder Monkey, so treat it as a first listen to the three circuits rather than a guide to the blend controls.

Why it matters

It is a heavily expanded version of the Bad Monkey overdrive, adding two extra drive circuits and a parallel blend controlled by the Barrel knob. That puts three overdrives' worth of gain on a single board slot, and the blend lets you run the voices in parallel instead of one after another. It was released in December 2025 with top-mounted jacks and a reversible StagePlate for mounting.

Note

A heavily expanded take on the cult Bad Monkey overdrive, adding two extra drive circuits and parallel blending for three pedals in one. Released December 2025 with top-mounted jacks and a reversible StagePlate.
