This is the V2 upgrade model. It's a multi-functional, high-quality, low-noise compressor that you wouldn't expect from a mini-pedal. I think it's the highest quality among those that prioritize the original sound. I've only used it a few times for home recording, so it's almost like new. I usually use high-end rack and plugin compressors for recording, but this one is comparable in quality and allows for a wide range of sound creation. Even applying it subtly and naturally will elevate the sound to a higher level of hi-fi without compromising the original sound. For the above reasons, I realized that I wasn't looking for a pedal-type compressor that prioritizes the original sound, but rather one that has its own unique character, so I'm putting it up for sale. ・Features A compressor from BECOS.
