Re: Compressor
A good compressor will definitely help even out your tone, as well as add punch and sustain in a way that you can't get from just an overdrive or distortion pedal.
I'm a recent convert to compressor pedals, and now I can't believe I've never used one before. It adds a nice, professional sheen to the tone that I really enjoy.
I use the Homebrew Electronics CPR compressor.
