Authentic amp stack sounds from a compact stompbox!

From fat crunch to ultra high-gain distortion, the BOSS ST-2 Power Stack distortion pedal 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 the years of amp-modeling research BOSS has done to bring you real stack sounds in a compact stompbox.

Tower of Power
The ST-2 Power Stack distortion pedal 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 smoothly 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.

Sound Knob
The SOUND knob is a controller that is uniquely BOSS. Simply set it to the tone type you're looking for. The SOUND knob not only changes gain but sound character as well, from brisk crunch and spectacular drive to earth-shaking ultrahigh gain.

Road-Tough BOSS construction
BOSS compact pedals are world-famous for their great sound as well as their road-tough construction, consistency, and reliability. The ST-2 Power Stack inherits this BOSS-proven design, offering guitarists a solidly constructed pedal that's built to withstand decades of demanding use.

Boss ST-2 Power Stack Distortion Guitar Effects Pedal Features:

  • Original distortion sound reminiscent of tube-based stack amplifiers
    Provides a wide range of tones, from vintage crunch to ultra high-gain modern distortion
    Faithful and accurate response to picking nuances and volume changes
    Sound Knob controls both gain level and sound character
    Two-band EQ with dedicated Bass and Treble knobs
    Road-tough BOSS construction

  • OK, But proceed with caution

    As reviewed by Neil Kraft on 1/16/2013

    I would love to give this pedal 5 stars because I think Boss pedals are the greatest thing since sliced tomatoes. Ive been a loyal Boss pedal stomper since the early 80s and still use them for performing, recording, and all sorts of audio manipulation.However we've entered the age of sound modeling and making small things look and sound big. The power stack is a good example of this. The Power Stack does make you sound like you are playing through a wall of Marshalls but this only happens while using a small combo amp at room level volumes. In fact it sounds great and would be a good recording pedal effect as well. Here is why I wont give it 5 stars: Using this pedal on a larger amp(100 watt) or even a 50 watt amp at higher volumes for gigging and performing just doesnt work tone wise or sonically. Setting the distortion level past midpoint (ultra) has a nice overdrive sound but a terrible hiss behind it. This may sound silly but what I look forward to in Boss pedals is their simplicity. My Blues driver, Super overdrive, and DS-1 do not have Bass/treble controls ,only one tone and a level, and I like that. I have enough choices in my life and more eq knobs just bothers me. The price is a bit high for a what it actually does, I know what it takes to build a distortion pedal and theres not much difference between the DS-1 or SD-2 as far as guts and the ST-2 Power Stack. I get the feeling popularity has a bit to do with the price of some of these pedals. All in all the pedal does what it says it does, but reading the fine print wont matter much, there is none, are none, whatever. Boss is trying to keep up with all the modeling technology out there, cant really blame them. Gotta try it before you buy it.

  • Good but buzz

    As reviewed by Anthony Baker on 12/30/2011

    I got this pedal on clearance at guitar center just after Christmas, and i love the sound. The only problem is the buzz when the drive is up high, but I'm planning on buying a noise suppressor next so it's not a huge deal. But it has a great range in sound. I can use it well with a low crunch for music in my youth worship band, or crank the drive for great punk distortion,and the bass and treble both go from none to a ton, so the range is fantastic, I would re3commend it but if you like lots of drive, consider a noise suppressor too!

    As reviewed by Damien Marshall on 5/17/2011

    This pedal can do anything. I brought down the gain and played some blues and funk on an SSS strat and then kicked it into full gear and played some death metal on my rg1527 7 string. that was one of my biggest things with this pedal, IT CAN HANDLE 7 AND 8 STRINGS!!!! I was tuned with a low F# at the time and it was very tight and clear. the guitar has stock pickups which are only about as powerful as a DiMarzio Tone Zone 7 and it still did every kind of metal from low end death metal to thrash metal and really tight djent. the gain can also be rolled back a bit to get that classic rock Marshall stack type of sound. Works great for punk as well. this is a great rock/metal pedal. By the way, until i got this, i hated ALL pedals and believed that they would ruin the natural tone of your guitar and amp but this really opened my eyes. so buy an amp with a perfect clean channel and a good distortion channel and let this do the rest. pair this with a good EQ and you will have a completely perfect and original tone
