Ready to rock? The Crazy Tube Circuits Heatseeker attempts to bring you the authentic rock sound of AC/DC. Many have claimed to have nailed Angus Young’s sound, but with Crazy Tube Circuits’ reputation, we might have to take it seriously.

Crazy Tube Circuits Heatseeker: 2 in 1

The Crazy Tube Circuits Heatseeker is designed to capture Angus Young’s sonic essence. It contains two different amp sections that offer all the versatility and Rock ‘n Roll drive you could ever ask for.

OIn the right side of the Heatseeker is a meticulous replica of the preamp and tone-enhancing circuitry of the famous Schaffer Vega diversity system (SVDS). This circuit keeps the lows tight and present while boosting the mids, creating a mighty wall of overtones and a punchy, penetrating sound that will shake you all night long.

On the left side, the Heatseeker offers an all-analog emulation of the preamp and the power amp sounds of three legendary Marshall amps: the JTM45, 1959 Super Lead, and JMP 220 3. It also includes controls to shape your sound, including a three-band EQ, presence, master volume, and amp voicing switches. Just with this section you’re probably able to create just about any AC/DC era you can imagine.

JFET, WoS, and FX Loop

The Crazy Tube Circuits Heatseeker uses an all-analog JFET circuit with an internal 27-volt boost. This provides a range of sounds with cleaner-to-meaner dynamics.

Wall of Sound (WoS): This simulates the sound of standing in front of a wall of Marshall amps and 4×12 cabinets. You practically become Angus Young with this switch, minus the uniform (and the legendary chops, of course).

Passive FX loop: Place your favorite pedals between the preamp/enhancer and the Amp-in-a-Box. Or, using an external bypass switch or looper, you can use the two sections as separate, independent effects. The flexibility is endless!
