OVERVIEW

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.

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

A wide range of tube-like distortion with loads of control for tweaking. Order now!

    Let's not beat around the bush here - when we're talking "stack" amps, we're talking about the classic sense of the word - Marshall. Make no mistake about it. This isn't another dirt pedal, this is a Marshall amp modeler. The models are more or less represented 3 general sound settings - Crunch (1959 Plexi), Drive (JCM800), and Ultra (JCM 2000 or some sort of modded high-gain Marshall), represent the range of Marshall tones that span decades.

    Its really simple - as the sound knob is turned, not only does the gain increase, but the character of the tone changes a bit as well (the mids tighten as the gain is pushed into metal territory); hence it being a "sound" knob and not merely a gain knob.

    What's great about this pedal is that if you're looking for something to give you that Marshall bite, its all right here and then some. Because this is designed as sort of an amp-within-a-pedal, whatever setting you have the sound knob at will respond to a boost or overdrive in a similar manner as the amp its emulating. In other words, if you have it on "Crunch", and put an boost in front of it, it will sound like a Plexi with a boost; it won't simply push the gain into Drive or Ultra settings. If you're familiar with amp models then you get what I'm saying.

    Because of its versatility, this can get you a mild grit for blues or country, chunky drive for rock, or high gain for metal (it won't sound like a Mesa Dual Rec, however). "Crunch" at a high setting with a single coil Strat = Hendrix territory. "Drive" with a mid boost and humbucker = Slayer. You get the idea.

    A slight disappointment for me is that this is still at the end of the day just a pedal/preamp type effect. It would be REALLY cool of there was a speaker cabinet-simulated stereo output to plug directly into a mixer or practice with headphones. Like a Tech 21 Sansamp, this could be a gigging musician's pocket powerhouse. Another issue that might be a deal breaker for some is that like with alot of amp modelers, the sound suffers from a bit of top end fizz in the higher gain settings. Not too much, but its there.

    I tested this pedal out at [@] before buying it from MF. It sounded pretty good at [@]. However once I hooked it up to my amp and effects chain, it sounded really terrible. I use a Fender Deville 2x12 and play an Epiphone SG. This pedal is really, really noisy in the signal path. I was hoping to get a nice Mesa/Marshall high-gain tone from it. Unfortunatelty to get anywhere near this tone you have to crank up the gain to the point where's there very audible static when the effect is turned on. Somehow I'm getting a better high-gain sound from my amp's distortion than from this pedal, which is weird considering the Fender Hot Rod series aren't really known for high-gain tone. The noise in the signal chain is a deal-breaker for me. I only have 3 other pedals, an Way Huge Aqua Puss, Boss Super-Chorus and a Dunlop standard Wah. There shouldn't be that much noise in the chain with only 4 pedals. Honestly I kind of feel like this pedal is a rip-off. For the price Boss is asking, there should be much better and quieter circutry in this box. I also feel like for the above-average cost for distortion units, there should be more EQ filters than just one bass knob and one treble. Overall, I'm really disaapointed with this unit. At this price point you should at least get a quiet pedal that you can tweak to your liking. Not a one-trick pony that's pretty much useless on stage and in studio due to the ridiculous amount of noise it generates.

    Comments about Boss ST-2 Power Stack Distortion Guitar Effects Pedal:

    The ST-2 is very good. Some consider it a little pricey, but it rivals the almighty Tubescreamer in my opinion for much less cash. The pedal puts out a nice full-bodied scream between three-quarters and full gain (I like it about four-fifths), but backs off nicely at lower levels without becoming unresponsive. The best part is that the ST-2 does it without that scooped screeching tone that cheaper distortions provide. Of course, it doesn't come with detailed EQ control. So what? It doesn't come with a juicer or bluetooth either.
    The ST-2 is a simple pedal that gets the job done right.

    Comments about Boss ST-2 Power Stack Distortion Guitar Effects Pedal:

    The problem with a lot of distortion, overdrives or fuzz pedals is that they are either too weak or have too much saturation. This pedal's controls are dynamic to each other, similar to the way a Mesa-Boogie amp's controls operate. Great stack tones from a little edge, "Pete Townsend" sound to a "Priest / Accept" Balls to the wall thick Marshall scream. There is very little feedback when you turn up the gain, which is a big plus. Also it does not reduce the tone quality of your amp, the way that some pedals can make a fine tube amp sound like a low end low watt practice amp. I have used this on several amps,(trans & tube), different brands, and it sounds awesome through each one. I may order another one for my pedal board just to have two different O/D settings.Get this pedal!!!!! Great job Boss.

    Comments about Boss ST-2 Power Stack Distortion Guitar Effects Pedal:

    Well, I have played many styles of music from metalcore, thrash, cross over, rock..nowadays im playing more jazz(Pat Metheny,etc) and lots of ska/reggae and spanish rock. This pedal covers alot of ground for any uses. I personally LOVE it. The Heavier settings remind me a lot of early testament sounds, especially for solos it has a good alex skolnick-esque sound to it. when you role it back you can get a great clean lead sound..especially if you dial back your guitars tone and volume knob. I have been through tons of amps and pedals. With my current set up(tube vypyr head) or even with any other amps This pedal is amazing..go out and try it. :)

      Comments about Boss ST-2 Power Stack Distortion Guitar Effects Pedal:

      A lot of people are negative on BOSS distortion pedals and digital modeling in stompboxes, so it's not surprising that the BOSS Power Stack has some doubters. Don't believe the "noise", though, try it for yourself.

      If you already have a Marshall half-stack, this pedal probably wasn't meant for you anyway. For the rest of us, it does a very nice job mimicking both clean and distorted sounds of a large Marshall cabinet. Really excels for lead guitar work. If you desire even more low end, check out the Marshall Jackhammer, but this an excellent pedal.

        Great little pedal which delivers distortion of all sorts. Great for Rock, Blues, Hard Rock, Metal, etc.

        Also great to use as a tone control...which is done by turning down the gain and just using the on board equalizers.

        I am a tone-snob to say the least, so I did my research before purchasing this product. Many professionals are using this pedal - Boss is a huge company for a reason.

          Decent Pedal

          Comments about Boss ST-2 Power Stack Distortion Guitar Effects Pedal:

          I bought the Boss Power Stack with relativley high hopes after hearing many positive reviews online about it and while I'm typically an optamistic person I'd have to say that this pedal really didn't meet my needs. While the quality wasn't really that bad on the pedal and it stayed functioning just fine, I couldn't get around the horrible lack of clarity in the sound. No matter how I tweak the pedal I've only found it to sound very muffled, almost as if there was a cardboard box on top of my amp. If it wasn't for this the pedal itself would sound pretty great actually, but the only way to get it to sound normal is to put an eq pedal in front of it and adjust it, and for that money I'd rather just buy another pedal that doesn't have this problem. I would consider that my pedal was just a lemon or that maybe it was just my amp but I played this pedal through atleast 5 or 6 different tube amps and I even went and played another Power Stack but the tone just wasn't there. I wouldn't reccomend it.
          The features it had were nice but I think it could use more Eq controls.
          The pedal was mostly sturdy but the jacks wont stay tight for anything and it got scratched up pretty easily.
          I got this pedal before the price was raised and I still think it was too high. I wouldn't value this pedal at more than $60

          from McAllen TX

          Comments about Boss ST-2 Power Stack Distortion Guitar Effects Pedal:

          Nothing much more to say. If you use a humbucker and want a great heavy old school sound that cleans up very, very well, then you should be happy.
          I'm into classic Van Halen/AC/DC tone and I really like this. I use a medium output dimarzio humbucker. I set the output and about 10 o'clock which is somewhat louder than going clean.
          I set the bass, treble, and "sound" (gain) at 2 o'clock. I am 56 and covered Led Zeppelin, Foghat, ZZ Top, Black Sabbath in the 70's (to my great amusement!) and have lots of tube amps and pedals and this pedal makes it quick to get what I consider a classic hard rock/old metal sound from a humbucker. What clinches it for for is that when I roll off the guitar volumes I get a wonderful, clean and bright spanky tone like EVH used to get when he rolled the volume down. So I really can go in my opinion from very bright and clean to total distortion and I don't have to endlessly tweak the thing to do it.
