In this video, Rhett Shull reviews the Clean by Chase Bliss. He says:

Okay, so to start off with, Clean is without a doubt an amazing sounding compressor. It’s really versatile. It’s actually quite easy to use. I think it’s pretty beginner-friendly, and compression is one of those effects that for beginners can be quite confusing. I know it took me a few years to really understand what compression was, how to use it, not just as a guitar player, but how to use it on drums and vocals and and mixing. But I actually think Chase Bliss has done a good job making this beginner-friendly.

With that said, however, if you’re someone that’s just looking for a compressor to put on their pedal board to use with their guitar or their base in front of their amplifier to do some basic compression sounds like evening out your dynamics, maybe going for that sort of squashed compressor sound or to give you more sustain with your overdrives, this will do that, but you would really be underutilizing this pedal. I think for that use case, there’s plenty of other options out there that are better and cheaper than this, like the 1176 from UA, the Pulp N Peel from JHS. There’s a lot of good compressor pedals that will do that job as well as this, and you’re not paying for features that you’re probably not going to use, like the physics and the different EQ modes. But if you’re someone that likes to use pedals for sound design or to mix with, the Clean is an amazing option because it’s true stereo in and out. You can actually use it like an outboard rack compressor like my Distressors up there, for example. You can put drums through this, put vocals through this, put your entire mix through this, and use it to do basic compression, gluing things together, to hard slammed limiting, to adding Distortion to EQ, like it’s a really powerful tool for mixing and for sound design, which I love.

So to wrap up, who is this pedal for? I think Clean is for someone who understands compression, they understand the role of compression in their sound, whether they’re a guitar player, bass player, producer, whatever. Someone who’s going to utilize all of the different features from the variable EQ modes to the physics low-fi thing to the dusty mode. I think Clean is an amazing sound design tool. If you paired this up with some reverbs, putting it after a reverb or delay or modulation effect, you can start to do some really interesting things with the control that this compressor and distortion circuit give you. Sounds amazing on guitars, both in front of and after amplifiers. It sounds amazing on bass. And even though I haven’t tried it yet, I imagine it works incredibly well for drum processing. And it also rewards someone who’s willing to experiment and sort of try new things. We didn’t even talk about the different IO options you have MIDI in and out as well as an expression and control voltage so you can use this in conjunction with your modular setup. And maybe most impressively, the side chain input, which lets you feed in a separate audio signal to trigger the compressor, like a kick drum for example. That’s really cool to see on a pedal like this.
