I put a Sunn 410 cab on layaway last weekend. I thought it was a super price so I didn't want to lose it before I had a chance to get a few questions answered. First, this model had the Sunn logo on the front. The grill was metal. The back had two 1/4" inputs and a coaxial input as well. There was no FMIC logo and there was no horn control knob. The only thing printed was 300W @ 8Ohms. Tried this cab out with a P bass going into a Fender Bassman 250 head. Was able to crank gain and volume to 3o'clock and bass to 3o'clock with everything else set flat and this is where it would start farting a bit. Turned down the bass and everything was fine. I liked the sound of the cab, but I haven't been able to find anything on a model fitting this description and I want to make sure it's actually a bass cab, not a guitar cab. At some point I need to bring my bass/amp to the store to make a final assessment, but what else can I look for to identify if this is a bass 410 or a guitar 410 cab? Thanks for your help.
