Whoa whoa whoa - "obscure"? Maybe in the US, but not in the UK. Doctor Who is well-known outside the US, and its following has grown here enormously. In large part because it's much more accessible now thanks to BBC America. In earlier years, it was more hit and miss on PBS. I never got into it in the earlier years - I think I tried an episode or two. Didn't stick then.
Didn't know what model the guitar in that ep was. I tried to find the amp from one of the eps with no luck.
And in the diner he was playing what appeared to be an Epi SG with a Bigsby. So now you have to go buy one.
