You'll be hard pressed to find a tube amp with a headphones jack. I have the Classic 50, which would be way too much for your needs. It would make that Fender 212R of yours sound like a little 10 watt practice/play amp. It sounds pretty good at low volumes, but really opens up with the volumes set like this: clean 5, dirty pre 8-9, dirty post 11, master 5 (amp goes from 1-12). That is rediculously loud though. But bring the master down to 2, and you've got a decent tone for practicing. The C30 would be much more suited for your situation, and still be plenty loud when you need it. I'd be willing to bet it can be as loud if not louder (especially witha 1x12 extention cab added) than your Fender. Also, don't you have some kind of modeler? If you find you aren't getting quite the tone you want at the lower volumes, run your guitar into the modeler and the modelers output into the FX return of the amp. On another note, I play all kinds of styles on my C50, everything from blues, classic rock, hard rock, and metal. If you're more into the high gain thing, you might want to look into getting a Digitech Bad Monkey overdrive pedal and run it along with the amps overdrive. I do this with an MXR Zakk Wylde overdrive and can get some really crushing tones. If you can, please go play the amp first. I would suggest starting with all tone controls at 12 o'clock. I usually run my C50 as follow's: bass 1-2 o'clock, mid 2-3 o'clock, trebel 4-5 o'clock, and presence depends on what room I'm playing in.

Good luck with your search for great tone!
