The AC-Tone pedal offers 2 channels of overdrive, voiced alike for preset usage, and also gives you a clean channel with a boost of up to 20dB. The overdrive is low to medium gain for a sweet and crisp tone with mellow midrange reminiscent of the old TopBoost amps from the late 60`s. The 2 channels range from a mild breakup to a healthy overdriven sound. One channel can be used for slightly chimey breakup, and the other channel set for more overdrive, with saturated mids and drive. Lots of flexibility means you`ll always have the sounds to meet your needs. The AC-Tone pedal has a built in regulated (+-12V) power supply, to secure the necessary headroom for great tone.
