Rivera Thirty Twelve guitar combo. If you've been wanting to try a guitar amp in paralell with the bass amp for distortion, or if you've got a guitarist that has to crank his 4x12 to "get the sound" ... plug them into this! Gets "the sound" at a reasonable volume. This is my favorite guitar amp to listen to. 30 watts, all tube, 1x12 open back, 2 channels (channel 1 is "marshall" or "british" voicing, channel 2 is "fender" voicing). I paid $500 used and will sell it for the same plus shipping if anyone here is interested. Mint condition. I bought it as a recording resource (did some killer tracks), but I'm not recording much these days so its just gathering dust. It records really well mic'd with either an SM-57 or AT-4033.
