Tower of power
The ST-2 delivers the playing feel and power that are hallmarks of stack amps. It was derived from Boss’ extensive analysis of the sound and characteristics of a vast number of classic guitar amps. This distortion effect delivers authentic tone and expression that responds naturally to picking nuances and volume changes on your guitar. But emulation is only the beginning, as the ST-2 has the ability to go beyond the sound of real amps.
Crunch, drive, ultra high gain
The ST-2 lets you enjoy a rich, clean tone when playing soft, and a smooth 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.
The SOUND knob is a controller unique to Boss. Set it to the tone type you're looking for and it not only changes gain but sound character as well, from brisk crunch and spectacular drive to earth-shaking ultra high gain.
Road-Tough Boss Build Quality
Boss compact pedals are world-famous for their great sound as well as their road-tough construction, consistency, and reliability. The ST-2 inherits this proven design, offering guitarists a solidly constructed pedal that's built to withstand decades of demanding use.
