Description

Unleash your inner rock legend with the Crazy Tube Circuits Heatseeker, an overdrive effects pedal that brings the electrifying energy of a live stage to your fingertips. This pedal is a versatile powerhouse, offering both an analogue preamp/enhancer and amp simulator, capturing the iconic tones of Angus Young from AC/DC. With its dual-section design, the Heatseeker lets you harness the dynamic Schaffer Vega Funk system on the right, while the left houses three distinct Marshall amp simulations—JTM45, 1959 Super Lead, and JMP 2203. This ensures you can craft the perfect tone for any riff or solo.

The Heatseeker is more than just an overdrive pedal; it’s a tone-shaping tool that provides an impressive array of controls like Enhance, Level, Master, and more. The Wall of Sound (WoS) toggle switch allows you to emulate the massive sound of a wall of amps, adding another dimension to your sonic palette. Each section of the pedal can be used independently, thanks to the relay-switched true click-less bypass and passive serial effects loop, offering seamless integration with your existing gear.

Designed with top-mounted connections for easy integration into any pedalboard setup, this pedal operates internally at 27 V DC, delivering increased headroom and a tube-like performance. Whether you're in the studio or on stage, the Crazy Tube Circuits Heatseeker ensures your sound is always larger than life.

Crazy Tube Circuits Heatseeker: Angus Young tone in a pedal | Guitar World

guitarworld.com

The Crazy Tube Circuits Heatseeker delivers an impressive range of tones reminiscent of Angus Young's iconic Marshall sound, enhanced by innovative circuitry that adds depth and clarity. Its dynamic response and versatility make it suitable for players seeking everything from classic rock to modern tones.
