at a practice studio: mesa solo rectifier heads, laney V100 heads, laney 412 cabs, mesa 412 cabs, ampeg 810 cabs and ampeg head (forgot which model). but the owner doesn't put these amps out anymore because most folks don't know how to treat the amps properly and end up blowing tubes and wrecking amps and breaking knobs and all sorts of stuff. i don't blame him.
at a recording studio: matchless chieftain combo, mesa dual rectifier 112 combo, ceriatone head (think it was a 45w marshall jtm45 copy), laney v100 retubed with NOS Phillips tubes, mesa 412 cab...there's more stuff that i can't recall right now. ceriatone is no longer there though. but it sounded sweet while it was.
