I've always wanted an AC30, and I must say I'm very happy with this amp. It sounds fantastic on both channels and sounds great with either my SG or my Strat. It has no problem getting that "Vox chime" and can get some surprisingly heavy tones too.
It is a very loud amp, but thanks to the built in attenuator you can still get great tones at a more home friendly volume.
If you are a fan of the Vox sound don't hesitate to get one of these amps. You won't be disappointed.
