Hamer Special Korina , Fishman, Gotoh upgrades

Hamer Special Korina.I'm told this was a pre-production prototype. Mass production was at different cheaper factory with cheaper bridge, smaller frets and lower quality. I'm open to trades for older guitars from the 70's or 80's.Hardly played. Many upgrades!!Fishman Greg Koch Gristle-Tone P90 set. Two of the pots are push/pull to access all 3 voices.Gotoh Locking TunersQ-Parts KnobsLocking Bridge posts.All original parts included.Fishman P90's are fantastic, and dead-quiet.There are extra holes from the original tuners and a screw where there was a 2nd strap pin.There are also a couple of minor blemishes on the front.With the upgrades, this is a totally pro-level guitar that sounds and plays amazing.As is, as shown, 10-52 Ernie ball slinky, standard tuning.
