What's a decent going rate for a yba-1 Corey? Also thanks a lot for the info!
No problem man, I want another one of those amps. The timing never works out between availability and funds for me over the past few years though. Going fair rate for one is generally around $350-550. Mostly depending on the condition, era and whether or not they've been recapped. If you get one for around $300, you'll probably have to pay for a (necessary) cap job. A lot of people have modded them to be more like a Marshall for guitar, with circuit changes and master volumes, you'll want to avoid those.
Oh, I realized I didn't address the low end question. They've got tons of low end, no issue there. It's a bass amp, but it's popular for guitar. I've used mine for guitar as well. Our guitarist used mine for one of two guitar tracks for the Warp Rig demo.
