The ST-2 lets you enjoy a rich, clean tone when playing soft, and smoothly transition into a fat crunch as you play harder — great for rock ballads or songs that require dramatic tone shifts. Imagine the powerful, driving sound of a stack amplifier. An authentic classic-rock tone is here as well, with crisp overtones. Turn up the SOUND knob for a heavy-metal tone. The ST-2 allows extreme high gain, but offers a powerful low-end and sharp edge at the same time.
