When I restore or refinish a Rickenbacker instrument, I often refret it. It's the best time to do it, takes only a couple of hours max, and makes the job of stripping and refinishing the fretboard a snap.
I do not use Martin frets, nor Gibson Jumbo. You are looking for trouble if you deviate from the factory fret heights and widths, in that you will never get the guitar to set up like it was from the factory--not a good idea in any case.
Here are some shots of my 325 (formerly a 320) which I refinned and refretted. My own method for finishing a Rickenbacker differs from the factory method in two major ways, but this has to do with my own work methods, rather than the superiority of either way. I'm sure there are a lot of unique and personal ways to tackle this. This guitar is typical of one of my refins.
I'm afraid you'll have to copy these or cut 'n' paste, as they do not show up as hyperlinks:http://img.photobucket.com/albums/v693/ ... 0shiny.jpghttp://img.photobucket.com/albums/v693/ ... ux/325.jpghttp://img.photobucket.com/albums/v693/ ... board2.jpghttp://img.photobucket.com/albums/v693/ ... tboard.jpg
The last picture is a sort of clue to one of my "tricks": A Rickenbacker fretboard , besides being "lacquered" (and this is only true for pre-1959 instruments, incidentally, the material is actually conversion varnish), also has a buildup (or "meniscus") of varnish on either side of each fret.
I spray the fretboard after the new frets are set (but before they're levelled!) with the guitar hanging vertically from a hook which is inserted into one of the tuner holes. When this has cured, I mask the entire guitar, except the fretboard, and I carefully scuff the varnish of the fretboard. I then stand the guitar on its headstock, and I spray the fretboard once more so the varnish collects on the opposite side of each fret. When this second coat has cured a couple of days, the fretboard is ready for levelling. I have a long levelling board which I fit with two different grades of sandpaper, and which is used to level the frets. But first the truss rods receive a minor adjustment to bring the neck straight. They need re-tweaking again in final setup once the guitar is strung.
For those of you who don't know me yet, I do this as a sort of hobby. I love Rickenbackers for lots of reasons that will be mentioned in future posts.
Not varnishing a fretboard? I guess it's a matter of personal taste; I find the varnished 'board to be one of the guitar's best aesthetic features!
