I picked up my 7620 last week from an ebay auction. I posted to the "vendors and auctions" forum about it, basically the auction title said it was a 1527 but it turned out to be a 7620, I got it for £200 (about 363 USD) so I was still pleased.
Anyway... I got it and it was filthy! The fretboard was quite crusty and the strings were rusty (the three non-wound strings were black with grime). The trem was also a little rusty (pic here..
). I went through Rich's setup/cleanup guide and it looks/plays pretty nice now. The only problem I had setting it up was that I'd forgotten the strings I bought were 10s so the trem angle needed adjusting.
Also, the trem still has rust in places, on the saddle locking blocks and the allen bolts that hold the saddles in place. What's the best way to clean the rust off? I tried WD40 on a cotton bud which has helped a bit (the cotton bud couldn't get into the tops of the allen bolts though).
Oh yeah.. It also didn't come with a whammy bar, is there anywhere in the UK I can get hold of one for a cheap price?
