Had a gig last night and I must say I only used the Piledriver pedal in my signal. Nothing else but a Les Paul or a SG and my modded Blues JR. We cranked up loud, and my jr is modded with a large transformer so I got 18 watts instead of 15, not sure that makes a difference but I was using a lot of it last night. Rhythm was loud and fat. My sound was more power amp distortion then pre amp, Setting were Master volume 7, volume 6, bass 6, treble 6, mids 6, reverb 0, fat was off, and I have a presence control that was all the way up. my boost pedal the piledriver was wide open for a 38 db boost. Since the amp was slightly on distorted it did compress the sound a little but the volume boost worked perfectly. Ideal would be use a distortion pedal for those tones and have the amp clean, but I didn't have a decent distortion pedal and wasn't impressed with the Thunderdrive Deluxe although in sound check I did play around with it, it needs a tone control though. Over all I would say the pedal was a great success for me and everyone in the band was interested in what I was doing different because I tend to have issues with either being too loud for rhythm playing or not loud enough for leads and I find myself constantly trying to adjust the amp to correct for the volume situation. I'm pleased to say with the help from this pedal most of those days are over.
