Has anyone ever heard a Trace 1818 (18")? Are they good cabs? I have a chance to buy one thats pretty much brand new for 300 bucks. I play a SWR workingmans 350 and a Hartke VX 4x10 cab. I like to play rock'n'roll/punk, but also enjoy playing some jazz as well, what do ya say, would this cab be a good addition?
