I picked up an Ampeg SVP-CL (w/ a QSC1450) about two months ago and have had the chance to get it out to 5 gigs or so. I can now officially say it rocks! I am closer to my ideal tone now. Though many people love the 800RB (my last amp) i always found it thin sounding. I would always have to scoop the mids to get a nice fat, smooth, warm sound ...which also lost me in the mix. the SVP-CL gets me that fat and warm tone i was looking for while still keeping the mids in the mix. I am digging the pre-amp 110% for finger style funky groove music. I don't really think it sounds great for slapping ( i only spend about 3 mins slapping when i play out so no biggie). You can use the ultra bass dial and scoop the mids and get that scooped mids slap tone but i can't turn around and mess with knobs during a tune. Most people would agree solid states are better for slapping anyway. So anyway I'm happy.
