I've had this tele from new, it's a 1987 Fender Japan '62 Reissue and over the years it's been through more pickup and hardware changes than I care to remember. Worst mistake of all was installing a Gotoh 6-way steel bridge. What a piece of junk, totally ruined the sound and wouldn't even adjust far enough to intonate the low E string properly. So this weekend I finally decided to revamp the whole guitar, new Wilkinson bridge, new switch to replace the 25 year old cracklefest and new CTS pots as the old ones were solid shaft (bought the wrong ones!) and no knobs seemed to fit them. As a result, I'd fallen out of love with the guitar and it was becoming neglected.
Just finished installing everything and frankly WOW! The Gotoh can gotohell. The Wilkinson intonates near perfectly and the brass saddles bring out so much snap and zing and upper mid response. It's been years since I loved this tele so much.
Tomorrow's job - replace a scratchy switch in one strat and replace the horrible die-cast cheapo bridge in another one with, you guessed it, a Wilkinson vintage trem.
The moral of the story is that not all upgrades are improvements. Ripping out hardware that seemed like a good idea at the time is the new upgrading.
