AMT ELECTRONICS TUBE PLATINUM. Satriani and Vai 7-String tone! Tube Platinum is a tube driven valve distortion with deep over-amplification effect. It is designed for the player who prefers a dense saturated sound produced by a valve working in strong limitation mode. Even at high over-amplification level the valve limiter used in Tube Platinum does not suppress the signal dynamics, which results in wide and bright sound. A favorite pedal with instrumental lead guitarists that want the best sound. Equipped with Low, High, and Distortion knobs for custom tone control. All AMT pedals are designed to sound equally as good through an amp or direct recorded due to built-in cabinet emulation circuitry. Perfect for live performance and in the studio. You must try one to believe it. The first time you plug one in, you will be instantly addicted to the "AMT Tone"
