Re: Vox AC30-like tone
you can certainly pick up a used ac30 CCH head for around 650 to 750. You might have to stretch the budget at that point for a decent cab.
You can get a used Deluxe reverb RI for your price, in great condition no less. If you wanna warm that baby up, throw an overdrive box in front.
Personally, I was in your spot 4 or 5 months ago, and wanted an AC15, AC30, a princeton reverb, or a Deluxe Reverb. After playing a lot of amps but not getting to play a DR, I did get to play a Vox Night Train. I ended up buying it with the matching cab for around 750 and I love it.
The night train has no reverb, but offers simple controls, is affordable, and sounds great. It can get loud and I usually don't have to turn the master volume past half. It has it's own tone but it's VERY vox. If you haven't played one, I recommend trying it. The thick mode can get fairly small-combo-Marshall-y but I dunno how well it does an AC30 impression as they wouldn't let me crank the ac30 I demo'ed.
Personally I don't think anything's that great at doing a cross between those two rather unique amps. Try the egnater rebel 20 if you have not already. Has el84s and 6v6s (the power tubes that are in the vox and fender amps) and lets you blend between the two for american and brit sounds. No reverb, dunno if that's a problem for ya.
I thought that amp was pretty cool, and has a bit of the blackface sparkle, but it's pretty bright and doesn't have that fender reverb to take some of the edge off. Also, it just sounded a bit lacking in the midrange compared to the night train, and, it lacks headroom. I can get headroom for days out of my night train but that egnater wanted to begin to break up around 1/3 on the gain knob. Not something I appreciated.
Well, there's my advice and experience. Honestly for now I'd say snag a Deluxe Reverb and an OD pedal. Versatility is key and you'll have it with that setup. Plus, the natural overdrive from a cranked deluxe is something pretty great in and of itself, I'm told. I love my night train but I still want a DR for "that" fender sound.
