I'm after a compressor and have read that the CS3 is noisy, but with little further information. Is that just at higher gain, or higher volumes, or is it noisy all the time? The BOSS is the budget option. Other thoughts are a TC E Hypergravity or Keeley Compressor Plus. I don't want too much colour from it, more to give that 3D sort of thing, rather than the squishy stuff... if that makes any sense - suggestions welcome. Thanks.
