Introducing the COMPRO-1 Compulator Pro. Same great sound as the original Compulator but with added features. It has controls for both Attack and Release, so you can adjust how quickly the compressor both turns on and off. You can finely tune your compressed tone to mimic almost any type of compressor (with the controls set at their fastest setting you have the same setting as our classic Compulator). We have also included a adjustable gain boost when you want deep compression at the flip of a switch or if you need to set up for two different instruments. Hand made in the U.S.A. using the highest quality components.
