MXR DYNA COMP The Dyna Comp Compressor is one of the most popular compressors of all time. Whether you want to tighten up your signal, add rich sustain, or create the percussive and clicky sound heard on numerous hit records, this pedal is straightforward and easy to use. For these reasons, the Dyna Comp Compressor has been the secret weapon on countless pedalboards for years.
This is a really decent sounding pedal. Too bad it's not reliable enough to trust at gigs. The output fades when it is switched on to the point that it's no longer a usable volume. Not the first one with the same problem and no, it's not a cable issue. I replaced this with an Xoctic SP pedal and it seems to be the best comp pedal for my needs.
