Ok...my main amp is a Rivera TBRSL-1. I've owned many amps over the years, and this is easily one of the best out there. Killer clean, mid-gain and high gain tones. Anyway, I'm looking for a pedal that will tighten up the amp and make single notes jump out more. I just sold a Timmy because I didn't care for the bottom end for rhythm playing....but the lead tone was great. Other pedals I've tried are: Maxon SD-9, OD-9, Boss SD-1, Keeley SD-1, Bad Monkey, MI Audio Blues Pro, Blue Boy & Tube Zone, Fulldrive II and FoxRox Zim. Each one of thes pedals was either too loose or too compressed (I still own the stock MIJ SD-1 and Bad Monkey). What else do you guys reccomend I try? How about the FDII Mosfet or maybe the Blackstone?
