Rattler Bass mk4

JAM Pedals has been hand-building effects in Athens, Greece since 2005. Founded by Jannis Anastasakis, they use through-hole components, point-to-point wiring, and hand-painted enclosures. Artists like John Scofield, Bill Frisell, and Nels Cline play JAM pedals.

The Rattler Bass mk4 brings the guitar mk4's features to bass: second footswitch for mid boost, clipping toggle for symmetric/asymmetric modes, and internal trimmers for boost level and bass content.

Optimized for bass frequencies while retaining the Rattler's signature dynamic response. Level, Tone, Gain controls. True bypass with clickless switching.
