Near perfect, just needs a few upgrades
I got this secondhand in very good condition for about 300 dollars, as a Beatles and Queen fan I've always loved Vox amps and I wanted a tube amp, so I'm lucky that Vox is one of the few big brands that offer a good cheap tube amp like this. In terms of size I assumed it was going to be tiny but it's actually much bigger than I expected, I think it's as tall as the AC-15. The sound is pretty good, it's not perfect but I think it gets about 80% of the way there for me, I don't think I need another amp anytime soon, I'd rather use the money to upgrade this and make it as good as it can be. I have three mods in mind, removing the bright cap in the master volume, making a new backplate to convert it into an open back cabinet, and changing the speaker for a Celestion Greenback if I can get my hands on one, after I do those it would probably be more like 90% of the way there and I could live without the 10%. For the price it's a good base for a tube amp.
Preferred Settings + Usage:
Gain at around 2 o'clock, bass slightly rolled off, treble slightly rolled up, gradually go up in volume until you find a sweet spot that both sounds good and isn't too loud.
Gain turned down almost fully, bass slightly rolled up, treble slightly rolled down for a deeper clean sound.

Love it !
I am a guitarist and musician, in general, I have played since I was about 12 and I'm 28 now. One thing that I search for in a good practice amp is the overall tone and of course price. I love that you sacrifice neither with this amp and it has the ability to play through a cab. Now it may be 4 watts but that is louder than you will expect but trust me I have had a few of these and they are loud. If you like Vintage Vox Overdrive and simplistic design and function it's great! The only reason I only give it 4 out of 5 stars is that I like having reverb built-in but that being said this baby takes pedals amazingly and you will not be disappointed after the speaker is broke in well.

Small amp; classic sound
I bought this amp second-hand on my birthday last year as a smaller option to my AC15. Nice little amp with classic British crunch.
