Wow. I've had my 1210 for a couple of months. Got it right after the band I was in at the time decided to hang it up for a while. So while I've been playing through the cab in rehearsals (and enjoying it), Saturday night was the first time at a gig.
I was not disappointed.
I used an SVT-4Pro mono-bridged into the 1210. The gig was a *loud* 7 piece band (2 guitars, drums, percussion, hammond b3, singer/harmonica - a lot of sound), in a small bar (~150 people capacity), no PA support, and a plywood stage, tile floors and tin ceiling - long and narrow bar. I got some raised eyebrows from the guitarists before the show (Where's your 4x10, dude? That little thing isn't going to cut it, etc.) The Schroeder performed magnificently. I placed it on it's side, with the 10" speaker firing up to help with stage volume. Fat, greasy sounds, and handled the lower range of my 5 string with ease. I had a lot of compliments on my sound, including some from the musicians in the crowd.
The best part for me was that the band's old bass player was at the gig, and I let him sit in on a couple of songs. Perception of volume/tone is one thing on stage, but I never get to hear what the audience hears. While he was playing I was able to move to different parts of the room and listen, and the bass was upfront in the mix, and cutting through like a mofo.
If that Ampeg head didn't weight almost as much as the cab, I would have made the load in/out in one trip. My initial reasons for buying the Schroeder were 1) size/weight and 2) power handling/tone. I'll be the first to admit that my b.s. detector is set pretty high, and reading statements that this little cab will hang with or outperform many 4x10s had me pretty skeptical. But Jorg's cabs are the real deal.
Now of course, I'll have to wave an angry fist because I want to add a 1212 for the big gigs (because, of course, if what I have is great, more is even better, right?

) Which means I'll need to get rid of the current head and start looking at either pre/power or a head that will go to 2ohm comfortably (db750?). Thanks alot, Jorg.
