Power Stack

PS-6

Authentic Amp Stack Sounds from a Stompbox

From fat crunch to ultra high-gain distortion, the ST-2 Power Stack delivers famous BOSS
distortion with a stunning amount of power that’s akin to coveted tube amps and professional
amp stacks. The SOUND knob simultaneously blends gain amount and sound character,
so you can quickly dial up anything from vintage crunch and punchy drive to full-assault
distortion. To add further detail to your tone, simply tweak the onboard two-band EQ to
taste. The ST-2 is one very unique distortion pedal, calling on BOSS’ years of amp­modeling research to bring you real stack sounds in a compact stompbox.
