My first and most loved guitar is a wine red Matsumoku Sheraton from around 1982. It is distinguished among other things by its frequensator tailpiece. A number of years ago I put '57 Classic pickups in it, and it plays and sounds great. One thing that isn't so great is the tuning stability - it just isn't as rock solid as I imagine a 335 would be. Anyway, I'd be interested in hearing from anyone who has modded a guitar like this - I would like to put some TLC into this guitar and am curious about what others have done, whether in terms of tuners, bridge, caps, wiring harness etc., and which things need no changing. Thanks.
