Extreme compression in a compact stomp box!

The Guyatone ST-2 Compression Sustainer Pedal has variable level and sustain controls that allow you to dramatically squash the input signal, yielding smooth, clean, bell-like notes that last for days. In addition, the ST-2 effects pedal features a direct on/off switch. When engaged, it blends in a dry input signal at equal volume with the compressed signal, eliminating the attack-altering characteristic common to other compressors. The ST-2 guitar pedal gets everything from chicken-pickin' tone to clean boost for overdriving the front end of an amp.

A Great Pedal

By Anonymous

from Undisclosed

The ST-2 is a well- built, and great sounding pedal. The "direct" on/ off switch is a nice touch, although I have yet to use it in a direct set-up. The unit is very compact, and that may be a plus to some, but I would prefer a bit more size. Typically, I don't switch the unit on and off often, so...no big deal. The ST-2 does well with my low to medium gain sound, and is fantastic with my Ric 12 string. It's hard to get a bad sound with this pedal, and with a little experimenting, I think anyone can really find "their" sound. I am very pleased with the quality, sound, and value of this unit.

This pedal takes you from a clear boost to tight compression. Works great with my setup. The direct switch is also great to add that extra umph that gets lost with other compressors.


Great pedal at an even greater price!

A decent compression effect that, IMO, is just as good if not better than those insanely overrated & overpriced two and three hundred boutique boxes! Sound is smooth and velvety with no noticeable alteration in the attack. Sustain is good holding on as long as you can stand it. All said, a great effect for a great price!

I've had this pedal for a couple of years and I have it on all the time. Next to my fuzz pedal this is the most important unit in my effects chain. This little guy provides the compression I need without affecting the quality of my high gain effect tone and at the same time provides sustain that Hendrix and Santana would approve. This pedal is a little gem.


Good Buy

By RambutanMan

I have been playing for a while now but never really had much in terms of pedals. I've primarily been a rhythym player but my most recent band was a three piece and so I was required to solo quite frequently. I was never really satisfied with my tone and a good friend/musician told me a compressor would be a great addition to my rig. After playing with this thing for a while I would have to agree. It has definitely helped out and at a fraction of the price of the more expensive pedals. I would say that I got what I paid for. It is not all that rugged in construction and I'm not sure how long it can hold up but I think i would probably buy another if this one broke. I like what I am hearing. For the money it's a good buy especially if you are like me and don't like to drop the big bucks. Buy One, it is definitely a good addition to the line up.


Pretty good.

I bought this pedal as a possible solution for my leads. My main high-gain tone on my amp is pretty decent but I wanted something to push the tone into that bubbly, liquid lead metal tone without changing the overall tone. My amp doesn't have a solo boost and after having tried the other obvious options (tube screamer, boost pedals, on-board boost circuit) I thought that a compressor might do what I wanted. I'm sure it's not a new idea but this pedal gives me a clean gain boost in the front end of my amp to push me more up front without adding distortion or coloring the tone, all while slightly compressing the signal, adding a smoothness to the sound. The overdrives and boost pedals I've used have either colored the sound too much or added a spikiness that I don't want during a solo. This pedal sounds very transparent and the evened out tone makes it easier to control my playing. I can't say that this pedal works better than others of the same type but I agree with other reviews that it adds very little noise, if any, and sounds very organic.To sum up this pedal works very well as a lead boost for applications where you're already using fairly high gain and like your present tone. The one down side is you need to use it in front of the amp...it won't work in an effects loop(it will actually cut the line-level signal volume in a loop). Only an issue because I like plugging straight into my amp but with good cables it's still ok.


My (other) magic little piece of green!!..

This completes my sound. It organically sustains and livens my clean tones, adds to a slightly dirty tone, and adds harmonic complexity and sax-like sustain on my high gain leads. I play a Gibson SG Standard (and a Epi g-400 with active Duncan Livewires) through a Marshall JCM 600 with a MXR 10-band through the e-loop with the little ol' ST-2 and I have any sound from Sparkle Pickin Clean, Angusized dirt, Van Halen harmonic crunch, to a scooped Mastodon metal meltdown. Complete your rig with the ST-2!


Very nice almost transparent compression

By JerrySizzler

I just got this pedal and it certainly does it's job well. All the notes on my guitar ring out evenly. Finger picked notes sound infinitely better than before. There is only a little bit of high-end loss that I notice but it's the harsher high-end so I don't mind it. It does add noise but a noise gate(I suggest the MXR) fixes that. A really nice pedal all around.


Amazing Pedal

This pedal is awesome! I mostly play chicken picken country and this pedal is the best Compression pedal I have ever played on! Not to mention it takes up almost no room on your pedal board. Very good pedal! I definitely recommend it!


The ONLY good compressor out there!

Why limit your tone in the first place when all you need to do is boost the tonal characteristics? Trust me. Once you buy this compressor you'll never need a new one again!
