Review: A Real Studio-quality Audio Compressor - Might Not Be The Best Choice For Stage Use - This optical compressor is an incredible bargain. Optical compressors have advantages over other types: they're predictable and won't compress strangely when confused, like digital compressors, they're reactive, sensing the music organically, automatically and adjusting their behavior, & the optics provide disconnection from the electronics lessening noise and providing a measure of both physical and auditory safety. This pedal has most of the compression controls you'd find in a recording studio's rack: attack, release, knee (or slope), ratio (compression, etc.. Most pedal compressors, including those costing 5X more, generally have two functional knobs: attack & ratio (compression). Sometimes they'll add a level control (which this one has also) and/or a tone control (bizarre and unnecessary, they're just giving you an extra knob to help you pretend they're adding audio "value." Thankfully this does not include that absurd nonsense). That's what I wanted, a compressor that was similar to the compressors I was used to using in the studio. I got what I wanted, but found when gigging live fidelling with & fine tuning compression settings is a pain and it's probably better to just have two knobs, like most have. The compressor is physical solid & impressive. It sounds fantastic. It's inexpensive, and super inexpensive when consider its feature set. Best usage case would be to dial it in before the show, & then tape the knobs down, or just leave the ratio/compression knob untaped so you could turn it. Setting the slope might be super necessary, but when playing live it just gets in the way if you're the one both playing and fiddling with knobs.. Review: Compression Pedal for Dummies (AND semi-professionals) - Before I give you my first impression, I think it important to know a tiny bit of background so you have some context. I'm a 34 year old bachelor who has been playing guitar, on and off, for almost 27 years. I am by NO means a Kenny Wayne Shepherd or Joe Bonamassa. I'm not even "your high school best friends cousin whose band is going to play the homecoming dance". I plink and plonk until something resembling blues, jazz, or classic rock hits my ears. Speaking of which, I'm almost literally "tone deaf", so I very nearly gave up on trying to figure out what compression on an instrument was supposed to sound like. Everyone I knew whose opinion I trusted on matters of audio production impressed upon me the importance of compression and mastering. Every explanation kind of used the same wording: "It squashes the peaks and valleys of the sound." I'm not a complete dullard, I know what compression means in modern vernacular, but knowing what it's supposed to do to a visual representation of a signal and knowing what it sounds like and when to use it are two VERY different kettle of fish. Well I saw this pedal for less than most of the Keeley/Wampler/JHS/J. Rockett's and it touted "professional quality optical compression". Great, not only do I not know what regular compression sounds like, I have to contend with different kinds!? Luckily I found the most amazing description of the difference between electronic (or maybe digital?) compression & optical compression in The Gear Page forum. I digress. I bought this pedal because it was inexpensive, and I knew I would regret not having one when I understood the effect. Well, it showed up today. It does not accommodate a 9V battery, but I had a power supply for my Orange Micro and used that. I'll get a 1spot eventually. I plugged it into my Focusrite Scarlett Solo, opened Amplitube 5, chose an "American Clean" amp (generic Fender) and started messing with the knobs. Didn't touch any settings within the software or on the audio interface and I got excited immediately because the difference between attack, release, and ratio (knee/slope) was all at once apparent and even obvious. I may not be able to tell you how this compares to a Model 670 Rack Compressor or anything. What I can tell you is that I now have one pedal that can work pretty well as a clean boost, a distortion pedal, and a fantastic and responsive compression pedal. I was sooooo skeptical, but I really like this. I do wish it supported batteries, but I'm not going to look a gift horse in the mouth. ## Features - This GB-CP is a professional studio compressor in compact pedal format.

While I must admit when the pedal intermittently worked in the few days that I had it, the sound was exceptional with the compression even and smooth and doing the job it was intended do to, and for under $100 the features were also impressive. However within a couple of days of gently using the pedal and dialing in my sound which was securely mounted on my pedal board , it started shorting out and finally lost all power. Either faulty solder connection or cracked circuit board in the manufacturing process. Also the output jack was experiencing connectivity issues. For a new pedal just outside the box this is unacceptable. A new item should work without any issues. Hopefully for the company's sake, this is either an isolated incident or they are fixing this issue on future units. No choice but to return the pedal. --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.sn/products/176129995-gb-cp-optical-compressor-guitar-and-bass-effects-pedal-black](https://www.desertcart.sn/products/176129995-gb-cp-optical-compressor-guitar-and-bass-effects-pedal-black) --- *Product available on Desertcart Senegal* *Store origin: SN* *Last updated: 2026-05-31*
