I have a Line 6 AX2 212 amp - fantastic amp, i must add. Unfortunately, it's taken a bit of beating whilst being on the road.

One of the dials (including the head of the pot) on the front of the amp has snapped clean off, as well as another that has become 'loose' and no longer registers when adjusting settings. The first one i wasn't so bothered about - being the delay/reverb dial i don't use. Ever. However, the one that's come loose is the 'treble' dial which is a big problem.

Firstly, can replacements be bought? Secondly, is it easy enough to get into the amp to sort this out?

Thirdly, before some bright spark suggests i take it to an authorised tech i'd like it noted that i live in Scotland - and thus there isn't a service centre for a good... ooh, continent or so

Any help gladly appreciated!
