I just got this pedal today. Haven't had much time w/ it at all, but this pedal is a tone enhancer. I'm playing this in the loop of a suhr badger. In front of the badger is a brown rabbit. I'm all about the 80's metal, but I also want a organic tone and feel is just as important to me as tone. I have the barber eq is set on the british setting. This setting adds a super nice grind to your tone. The pedal seams to impart a very suttle enhancement (doesn't change the tone of your amp.) I didn't try this pedal infront of the amp w/ the brown rabbit or on any other settings. I just plugged it in the loop and had a great thing happening so I didn't want to mess w/ it. Sounds like a balnket has been taken off my amp, but the best thing is that GRIND! (If you have the pedal you'll know what I'm talking about) I'm interested to here from you guys that have more experience w/ this pedal. Suggested settings, placement ect. Thanks Bob T.
