"In use, it's a low distortion, very quiet, very usable sustain unit. It behaves more as a limiter than a compressor - onset is quite abrupt. It sounds quite different to the usual Dynacomp and its clones. It has a smaller range of control than a Dynacomp, but sounds more "natural" because of that. Notes really hang on, and it's wonderful to drive a dirt box with a consistent level. You know the problem - the dirt box has a particularly sweet spot where it's just exactly right, but playing too loudly or too quietly spoils that magic sound. This box will go a long way to mitigating that problem."
