Crazy Tube Circuits HeatSeeker

The Crazy Tube Circuits HeatSeeker is a versatile dual pedal that combines the legendary wireless preamp circuit of the Schaffer Vega Diversity System with three iconic British tube amp simulations. Known as the secret weapon behind the tones of AC/DC, Kiss, Pink Floyd, and others from the mid-1970s, this all-analog design captures the essence of rock guitar’s golden era.

The right side features a dynamic expansion circuit that enhances the dynamic response and harmonics of your guitar signal, giving it punch and attack to cut through the mix. The enhance knob provides precise control over the dynamic response, from subtle sparkle to bringing life to even the dullest sounds.

The left side delivers all-analog JFET-based amp simulations running on 27V via an internal voltage booster, capturing the tone and feel of three British tube amplifiers synonymous with rock and roll. The “Wall of Sound” circuit opens up the soundstage with thundering lows and dense high mids, creating the massive projection of a wall of tube amps and 4×12 cabinets. A passive effects loop allows for integration with other pedals or independent use of both sections.
