So my question is: In your opinion, which of these three would be better served as the clean boost in front of this Ceriatone amp? BB-AT Preamp AC Booster Comp RC Booster I certainly will try all with only volume maxed, zero on gain and eq neutral. Just wondering if you all had any experience with these pedals. I have all three and use them with my Tremoverbs, but I read somewhere that the BB preamp was likened to a Tube Screamer, but with some improvements. Thanks guys.
