Does such a thing exist?A mate's after one to put in front of a clean amp, and I'm really struggling to come up with any suggestions. He has an Xotic AC+ which is more of booster, so it doesn't do the job he thought it might. Tubescreamers and my Klone are a bit middy, and a fuzz pedal is too fuzzy!ZVex Box of Rock might do the trick? Anything else?
