i agree with nick, you really need to get out and try as many amps as you can- most amps at the £1500-range will be kickass to someone. I took about a year before i bought an expensive amp (including trips to mainland GB), and still ended up buying something i hadn't tried as i got such a good deal (and ironically probably made a better choice than if i'd relied on my judgement at the time :lol: )...
my advice is, try everything you can... but don't be swayed by an amp which does a tone you'd love to be able to get (which you can't get at the moment), if you only rarely use it.
I was extremely disappointed with my avt's modern tones... yet now I can get modern tones, I realise i don't use/need them all that often. though of course it's nice to be able to get them when i do want them.
