Crazy Tube Circuits Heatseeker Overdrive/Boost Pedal

Classic British Amp Tones with Dynamic Enhancement

The Crazy Tube Circuits Heatseeker is an amp-in-a-box pedal designed to capture the essence of classic Marshall tones, particularly those associated with Angus Young and AC/DC. Featuring three selectable amp voicings, a built-in boost, and a harmonic enhancement circuit, the Heatseeker delivers everything from glassy cleans to cranked British overdrive.
