thanks all for the good advice! :)
davemc: the avt112 doesn't sound that good then, also some negative comments on harmony central about build quality.
philking: as you note, 1x12 cabs seems totally bad value for money. your idea that a 2x10 cab might be the way to go seems really well informed. however, i'm using it for recording too, kind of metally stuff, so i think the extra low end of the 12" speaker might be the thing. probably for practise the 2x10 would be a much better choice. i dont have much experience with cabinets, so your advice is really useful, so far i've been recording direct.
chrisola: so i'm very interested in your 1912 cab. i'm a bit nervous to buy something i've never seen or heard, from someone i just met on the internet though ;) however, you seem very well known around here, with 100s of posts - so lets talk! i've sent you a PM.
