I had my Luthier install the K&K Trinity pickup/mic on my old J-50. If I Like it, I'll have it installed on my Dove too.
While he had it, I had an old set of Grover Tuners laying around, and the Kluson tuners on the J-50 were hard for me to turn with my arthritis,
so I had him change the out.
The Pickups are great.... haven't figured out the mic yet.... but the tuners not only look great, but the guitar is much easier for me to tune now.
This guitar is my workhorse. I play it most every day.... I like it even better now.
