Boss ST2 Power Stack Pedal

The ST-2 Power Stack brings the thunderous sound of professional amp stacks into a compact stompbox format, utilising BOSS’ extensive amp modelling research to recreate authentic tube amp characteristics. This unique distortion pedal offers everything from vintage crunch to ultra high-gain distortion, with the innovative SOUND knob simultaneously controlling both gain amount and tonal character for quick access to any style from punchy drive to full-assault metal tones.

Built on BOSS’ comprehensive analysis of classic guitar amplifiers, the ST-2 responds naturally to your playing dynamics and picking nuances just like a real stack amp. The pedal maintains rich, clean tones during soft playing and smoothly transitions into fat crunch as you dig in harder — perfect for rock ballads or songs requiring dramatic tonal shifts. The onboard two-band EQ allows further refinement of your sound to suit any musical context.

The ST-2’s SOUND knob represents BOSS innovation at its finest, functioning as more than just a gain control by simultaneously shaping the pedal’s sonic character. From crisp classic rock overtones to earth-shaking high-gain metal sounds, this single control provides access to the full spectrum of distortion tones while maintaining the powerful low-end and sharp edge that defines professional amp stacks.

Like all BOSS compact pedals, the ST-2 features the legendary road-tough construction that has made these stompboxes industry standards for decades. This proven design philosophy ensures consistent performance and reliability that can withstand the demands of professional touring and studio use.
