Played for half of band pactice tonight, sounded fantastic. I ran a combination of both channels and had this just killer, dark growl going on. Matched up really well with our other guitarist's Matamp GTO 120. I usually play on the neck pickup, but with my Flying V, I played the bridge more tonight. Tried a Hartke 4x12 guitar cab and was OK, switched over to a better cab, my Orange PPC412, and oh yeah, it rocked! Didn't want to punish it to much before it gets the once over from my tech, so I switched over to a Marshall DSL that I use for rehearsal. No comparison, the Sunn smoked it tone wise. I kind of want to use it for a gig Sat night, but until it gets checked out, I'll hold off. My Orange RV100 sounds great so its not like I have to sound like ass or anything lol. And since I don't have cleans (until I get the footswitch figured out) I'd have to run two amps, which I did tonight when I used it, I have an ABY switch and used the Marshall for cleans. I'm very happy!
