I hate to use the word transparent, but it doesn't color or change the sound at all. It's the sort of pedal that you don't really know it's there until you turn it off. I have various playing styles and basses, and it doesn't over compress on any of them. You can change the compression ratio of course, but with several compressors, the harder you play, in my experience, they ten to compress more rather than just limit the volume. I like the knee switch as well, it has 3 different settings and none of the releases are audibly noticeable. I caught one on here for 25.00, what a deal it was.
