I'm not talking about running it at break up. I'll probably use the master volume plus a couple pedals for some extra boost. And no I haven't, I'll look into them though.
Just my opinion, but I own a Classic 30 and I don't think you will be able to play it low enough and get the sound you want....it's not really a bedroom amp (dorm amp).
It won't be all that quieter than the AC30 I don't think.
Have you thought about an attenuator?
I've had both...the Classic 30 is great, but it isn't gonna be much quieter than an AC30 as others have said. I think you can get better cleans at a lower volume from an AC30. That being said I love both amps, there really is not great dorm room option. If I were you though, I'd keep the Vox and get an attenuator as someone else mentioned...Z Brake Lite
I'm not trading or selling my vox, just looking to pick up something in addition. Looking into the AC4 also.
I'm in the camp that thinks the Peavey Classic is a nice amp for the money, but I wouldn't buy one for low volume use. 30 watts in a tube amp that doesn't have power scaling or power reduction options is really just too much.
Also, the classic 30 is a fabulous amp, but I also agree that it won't be much quieter than your AC30. I also would NOT replace the stock speaker. I think the blue marvels are voiced great for that amp. They're high quality eminence manufactured speakers. Not crap.
