The BOSS ST-2 Power Stack guitar effects pedal is a powerhouse that brings the legendary BOSS distortion to life. It offers a wide spectrum of tones, from a rich, fat crunch to an ultra high-gain distortion that rivals the sound of coveted tube amps and professional amp stacks. The unique SOUND knob lets you easily blend the gain amount and sound character. With it, you can quickly switch from a vintage crunch and punchy drive to a full-on distortion. To fine-tune your tone, use the onboard two-band EQ with dedicated BASS and TREBLE knobs. This distortion pedal stands out as it leverages BOSS’ years of amp modeling research to deliver real stack sounds in a compact stompbox. It has an original distortion sound similar to tube-based stack amplifiers, responds accurately to picking nuances and volume changes, and is built tough for the road. Specifications include dimensions of 73 mm / 2-7/8' W X 129 mm / 5-1/8' D X 59 mm / 2-3/8' H, a weight of 440 g / 1 lb (including battery), and comes with an owner's manual, a leaflet, and an alkaline battery (9 V, 6LR61).

Using the BOSS ST-2 Power Stack guitar effects pedal is a breeze. First, connect it to your guitar and amplifier using the appropriate cables. Once connected, turn on the pedal. Use the SOUND knob to adjust the gain level and sound character. You can start by finding the basic tone you like, whether it's a vintage crunch or a high - gain distortion. Then, use the BASS and TREBLE knobs on the two - band EQ to add more detail to your tone. When you're done playing, turn off the pedal and disconnect it properly. As for maintenance, keep the pedal clean and dry. Avoid exposing it to extreme temperatures or humidity. If you're using the battery, replace it when the power starts to fade. Always refer to the owner's manual for more specific instructions and safety information.
