I tried out a boss cs-3 today. It did what I was looking for, but added A LOT of noise both when the pedal was on or off. I'm looking for something similar that meets the following: Mxr sized box preferably(this one is negotiable) adds sustain adds clarity to complex chords tightens things up. I'd be using it most for clean picked parts to keep the dynamics consistent, and for complex chords, so that some of the notes don't get as lost in the mix. The cs-3 did a pretty good job, but just messed with things too much and was way noisy. So anyways, any suggestions?
