File:Gibson Les Paul Goldtop retrofit based on 1973 Gibson Les Paul Deluxe (SN 620310) Switch tip (2010-02-28 by TT Zop).jpg

The pickup selector switch tip shone stark white after being polished perfectly smooth (no more seam). A little Kiwi Brown shoe polish on a piece of synthetic steel wool toned it right down.

Putting on a new poker chip? Don't forget to peel the paper off the adhesive backing! I buffed this one up just a little to knock off some newness and sharp edges. The original had turned unreadable and orange.

A 1/8" thick rectangle of maple was screwed into place underneath this neck pickup, using the original mini-humbucker mounting bar holes, to bring it up to height. For both pickups, the height is 1/4" from the top of the cover to the bottom of each E string. The pole peices were adjusted up to follow the curve of the 12" neck/bridge saddle radius, then tweaked by ear. (I also aligned the slotted heads horizontally, for no good reason. I've since decided vertically aligned with the strings looks better).

Many guitars have their pickups raised WAY too high...affecting both playability and sound. Gibson factory settings for humbucker height is 3/32" for the bass side and 1/16" for the treble. I don't know what it is for P-90s, but these pickups have BIG coils (and TWO magnets). Much higher than 1/4" and the magnetic fields were beginning to affect the sound in an undesirable way.
