Please don't think I'm too stupid but could someone please explain what a clean boost is. Does it just mean to use the distortion pedal without turning up the gain on it? I have a single Recto that I just love the distortion on, but I want to tighten it up a bit. I have read that if I add a clean boost it would get me what I want. Any insight and how to's would be greatly appreciated. Just thought I would let everyone know that I am a first time MESA owner long time DSL owner. Selling my DSL I have no need for it now that I have my single rectifier. Man this thing just screams. Wish I had found this out alot earlier.
