Description
Laying claim to an impressive lineage, the MXR M-132 Super Comp is the streamlined successor to the iconic Dyna Comp, offering you the secret to the coveted "Nashville sound". This pedal not only helps you to maintain the sweet sustain of your guitar's initial volume but also allows you to control the sensitivity to achieve just the right amount of compression. Housed in a super-tough, gig-ready enclosure, it comes equipped with a bypass footswitch and LED for added convenience.
Just like its renowned predecessor, the Super Comp is your key to unlocking improved control, consistency, and sustain. But it doesn't stop there; this pedal also excels in enhancing the dynamic response from hot humbucking pickups, making it a truly versatile addition to your pedalboard. With attack, sensitivity, and output knobs, it gives you complete command over your guitar's signal, making it easier for you to tweak your sound on the fly.
The Super Comp holds true to the adage that less is more. It doesn't overwhelm you with knobs, instead, it focuses on three key ones - sensitivity, attack, and output. These knobs help you set the compression threshold, determine when the signal is compressed, and control the final volume, respectively.
Key Features:
- Footswitch toggles Effect On/Bypass
- Output knob sets compressed (attenuated) output level
- Attack Level knob sets the attack attenuation level
- Sensitivity knob sets the compression ratio
- Power: Single 9-volt battery or Dunlop ECB-003 AC adapter (sold separately)
- Road-tough metal enclosure
- Indicator LED

VERY GOOD AND CHEAP
Pros: 1. Classic Compression Sound
Offers that iconic squash and sustain that’s great for country, funk, and clean rhythm playing.
Smooths out picking dynamics very effectively.
- Attack Control
Unlike the original Dyna Comp, the Super Comp adds an Attack knob, letting you adjust the initial transient — so your picking attack can stay snappy or be softened.
- Simple Layout
With just 3 knobs (Output, Sensitivity, and Attack), it’s very easy to dial in.
- Durable Build
Like most MXR pedals, it’s built like a tank — metal enclosure, reliable switch, solid knobs.
- Affordable
Often more affordable than boutique compressors but still delivers solid performance.
Cons: 1. Noisy at High Sensitivity
When cranking the Sensitivity for heavy compression/sustain, it can introduce some hiss or noise — common with analog compressors.
- Limited Versatility
It’s designed for a specific tonal style — if you’re after a transparent or more modern studio-style compression, this might not be ideal.
- No Blend/Mix Control
Can’t blend the dry signal with compressed one — useful for more natural-sounding compression, especially for bass or dynamic guitar parts.
- Less Transparent
Adds a bit of coloration to your tone, which might be unwanted in certain genres like jazz or ambient.
- Not True Bypass
Some units aren’t true bypass, which may slightly affect tone when the pedal is off (though it's buffered, so it can help with signal loss over long cables).
If you're playing funk, country, or pop rock and want that snappy, squishy tone, it's a great choice. If you're after more transparency, blend control, or want to use it on bass, there might be better options (like Keeley Compressor Plus or MXR Bass Comp for bass).

Dyna who?
I was using a Digitech Compressor/Sustainer, and it gave me nothing but a very squished sound, lots of noise, and almost no control over the output level - as a sustainer pedal (even with some noise) it was great, though. I got rid of it about 9 months ago. Around a 2 months ago I got a second hand MXR Super Comp and a new Dyna Comp (they were around the same price). I returned the Dyna Comp and the Super Comp stayed. What a great compressor! Awesome response from the knobs, and it doesn't add as much colour to the sound as the Dyna Comp. I also like the extra Attack Level knob, which provides way more control over my sound. I don't play strats/single coil guitars, so maybe that's why I didn't like the Dyna. As a Les Paul fan to all the Humbucker lovers out there, give the MXR Super Comp a chance to show you a new world! (Unless you own a TC Electronic Hyper Gravity, than you're good already)

When it comes to Compression it's gotta be Super
I knew what kind of Compressor pedal I wanted. It was the Ross Compressor but as musicians we all know how much they along with the AnalogMan Compressor pedals cost. So I decided to go with the MXR. I've only had it for about 3 weeks and it's a great compressor pedal. I won't got with another unless AnalogMan gives me one for free. C'Mon Mike!!! \m/ (-_-) \m/
Loads of sustain
This is my first pedalcompressor, and i like the sound I get from it. Only drawback is that the knobs are so easy to rotate that I might accidentally change my parameters with my guitarcable for instance. Dont know if this applies for all MXR pedals but i like them being firm as on BOSS pedals.

Preferable to the Dyna Comp
I have both. This is brighter, louder and the attack knob gives you more control. When faced with a choice between the two, this is the one to go for.

Not a Bass pedal
My rating should only be seen as it's relevance to bass. My guitarist says he loves this pedal but when I use it it sucks all the low end out of my tone.

Iw as about to make a really detailed response about how compression works in general and also how most guitar and bass comp pedals are designed but instead I'llpoint out that there are ltos of good bass comp epdals on the market (including oen from mxr) that are designed to alleviate the low end suck of heavy handed compression on bass isntruments... on top of that a guitar comp will probably have a small input cap compared with a abss comp and those iput capacitors form a basic highpass. its reducing frequencies that aren't msucial coming off a guitar pickup but those are often your fundamental on bass so you need less input filtering.... that's the difference between specific bass distortion effects and the regular guitar ones usually too. 1 part! A bass compressor will probably have some interesting filtering in the detector circuit too, what ew call a sidechain, probably something you've ehard of if you know any EDM/DJ?producer wannabe types ;-)

I know, I have a proper compressor for my bass, just saying this one doesn't work the way I wanted it to. I'm sure it's great :)

Classic compressor
Classic compression for cheap, no true bypass, simple controls. If you expect something more exciting - go for more expensive pedals.

Important pedal that does not too much
Use this as a clean boost, but like what it did to the sound, now leave it on all the time.

Why the Behringer DC9 is a good alternative: 1. It’s a clone of the Dyna Comp The DC9 is modeled after the classic MXR Dyna Comp, which is the foundation of the Super Comp. That means it gives you that same squashy, vintage-style compression: smooth sustain, leveled dynamics, and that little “snap” on your notes.
- Crazy affordable Usually priced around $30 or less, it's one of the cheapest compressor pedals on the market.
Perfect if you're just getting into compression or want something for practice/home use.
- Same simple control layout Just like the original Dyna Comp, it has two knobs: Level and Sensitivity (basically the compression amount).
Easy to dial in — you won’t get lost in tweak-land.
Surprisingly good tone For the price, the tone is very respectable. It compresses well, sounds decent through amps or headphones, and gets you into that funky/sustained clean tone zone.
Great for experimenting If you're not sure you’ll use compression all the time, it's a low-risk way to test whether it fits your style.
