Crazy Tube Circuits Heatseeker Preamp/Enhancer

The Crazy Tube Circuits Heatseeker is a powerful preamp/enhancer inspired by the legendary analog circuit from the ’70s that shaped countless iconic rock rigs. This pedal adds dynamics, harmonics, and percussive attack to your tone, making it feel like you’re playing through a wall of amps.

Featuring an all-analog JFET circuit running at 27 volts via an internal voltage boost, the Heatseeker captures the essence of three classic British tube amplifiers known for their clean-to-mean dynamic response. Its unique “Wall of Sound” circuit expands the soundstage with thunderous lows and dense mids, delivering the ultimate rock tone foundation.

A passive effects loop allows you to integrate your favorite pedals between the two sections, giving you the flexibility to craft your ideal rig.
