The AC-Tone Single Channel is a compact, single-channel model in the family of Carl Martin's popular AC-Tone. This drive pedal features a single AC-Tone overdrive. The AC-Tone wasn't originally high-gain, but by making it a single pedal, it's become a versatile pedal. The Drive knob offers a wide range of adjustment, covering everything from booster-like use to a satisfying crunch. It also features a 9V DC power supply for convenience. (Note: Since there is no battery compartment inside the unit, it only runs on an AC adapter.) Its compact size and easy powering options make it easier to integrate with other effects pedals, making the AC-Tone even more accessible. The AC-Tone overdrive delivers its distinctive distortion character and quality, no matter what amplifier you use.
