I agree with Roo - I wouldn't say "proud" anymore, although I probably was extremely proud the first time I hacked around inside, put it back together and... it still worked!!! (this was many years ago).
Definitely give it a go, but make sure you've got the tools - you need a decent soldering iron and (I always used to mess this up) the CORRECT screw-drivers for your pickup surrounds or whatever screws need moving. For years I lived with one or two screw-drivers and just jammed 'em in and started turning... Pretty soon, the head of every screw and allen-bolt you own will be f*cked if you do it this way! :lol:
Oh yeah, and get yourelf an old tea-towel or something to protect the finish while you're soldering - solder can spit. (Probably ought to protect your work-space as well, eg the missus/mother/whoever will not understand the burn marks on their table/carpet/whatever :D)
Lastly, this seems so obvious, but you will mess up on it... DO NOT FORGET THAT THE B*STARD THING IS VERY HOT (I'm one of the many people on here who will probably admit to absent-mindedly reaching for the iron and grabbing/touching the wrong end...)
But do go for it... if I can do it, most people should be able to.
