I've had this for over a week now but last weekend's gig was cancelled due to snow. Finally got to plug it in last night, at drummer Conte's 50th birthday party (yeah, he worked a couple of short sets on his own b-day). After the gig/celebration was over we all tied one on at Conte's house and I'm still a little fuzzy-brained now, but here are first impressions and a couple of pics. First: according to Jim B., the NV-610 is a very different animal from his hi-fi HT series cabs. It's a tweeterless sealed cab, designed to be like the old SVT 8x10 but smaller, lighter, louder, and with better frequency response. When I told Corey (aka GIBSONGEEK) at Rock City Guitars that I played fivers, he immediately reminded me that this cab isn't necessarily the best choice. I told him I wasn't expecting my pants to flap from the lowest notes (as they do with my HT series cabs), I wanted a robust old-school cab in my collection. Long story short: this cab delivers the old-school mojo! Nope, my pants did not flap from below-E fundamentals, nor did I get Marcus Miller *ping* when popping the G. What I did get was tight punchy tone with balls. Yeah I have a rack rig and not a pre-Magnavox all-tube hernia machine, but I goosed the gain on my Alembic pre and got some sweet growl. The room we played was rather boomy and I probably would've had a tougher time with my HT212. However my tone cut through fabulously, and I got compliments from my musician friends who said it was tightly focused and well-defined even in the back. Note that I get no PA support. My bad back and I have been arguing over whether or not to get a vintage SVT head. I haven't won the argument yet, but I am jonesing MUCH harder for one. Next time I fire up my new baby I'll use my SABDDI and hear what happens. Gonna shut up and post pics now.
