I love the ease of use, pretty easy to figure out once you "Get" how it all works, but this box REALLY destroys my overdrive/distortion tones. BAD. All my presets are crap on a Cybertwin/Ibanez rig. (Rig?)
You probably know that PF should be in your effects loop if you are using distortion in your amp's preamp. It will mess up everything if it's up front before distortion.. would be like feeding a complex chord (several different notes) into distortion: a mess. Just a thought.
