Boss ST-2 Power Stack

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 amp modeling research to bring you real stack sounds in a compact stompbox.
