BOSS CS3 HIFI and BEYOND MOD
The Kinnatone BOSS CS3 HIFI & BEYOND mod
will make your Boss compressor have a more Hi-Fi sound.
It increases the Headroom on the level control and also improves the tone control to have more available bass and mids while retaining highs. This turns your Boss compressor into the quality of a boutique comp that would cost you 3 times as much. I also change the Led to a color of your choice.
