Does exactly what is needed
It's not the world class compressor you see in studios, but serves its purpose quite well for the $. Mainly good for live situations IMHO, it provides just a little bit of oomph when needed, especially if you use several pedals in your chain that can sometimes take away from your tone just because of the physics of it all. I typically use this pedal right after my distortion or overdrive pedals, or right before I send the signal back to the amp. I typically place this pedal after my distortion or overdrive pedals. Of your amp has a dedicated effects loop, this pedal works best, as the signal is maintained better rather that an inline-before-amp-input where volumes and gain will fluctuate. The steadier The signal, the better it performs in my observation.
The limiting function is fairly harsh at times especially if you are using a clean channel. The limiting capabilities work better with over-driven or distorted tones, as it can lasso up what can quickly become out-of-control harshness that sometimes plague distorted tones where the sound spectrum of your tone is all over the place, especially at louder volumes. If you play heavy rhythms at loud volumes, this pedal in the limiting setting can tighten up the sound, and can save your speakers from rattling themselves to death.
If you are looking for a transparent compressor, you will be better off with a higher end boutique pedal. But if you are needing a quick, go-to compressor/sustainer/limiter in your live setup, this pedal will work quite nicely for the price point.
