i'm a hack on guitar. it's been a long time also so the gear is gathering dust. i tend to either windsurf or play music and at the moment i'm more windsurfing.
i have an ats 120 which is tube preamp solid state power amp. the clean channel is the most impressive blues sound i've heard. it's bassy and very round. also got a roland cube60
i like the lead channel but the crunch tends to be a little to "metal" at times. (edit* started wondering whether it is the other way round?) usually use it with a ds-1, big muff or small clone and my much loved godin radiator... (which is apparently a girls guitar

)
i agree with hairy on this one. i've been fortunate to use a few different valve heads and the H&K isn't an allround head. that said i haven't had much use on the all valve H&K heads.
my fav is the orange ad30 for all round sweetness.
have also used a vintage music man amp with fender setup and they are sweet. not much of a fan of fender amps though.
also used a marshal jcm800 with a les paul and flying v setup. the flying v makes me smile.

don't start me on effects pedals. i bought a lot and think i may have wasted some money.
