Lefty GMP Proto


We are selling this guitar for a long time friend and customer. He brought the
guitar
to our shop the day he received it from the builder, and we can verify
that his following
description is accurate. 

"For those interested, GMP was an American guitar company located in San
Dimas California, and was in existence from approximately 1990 to 2005.

GMP only made 1,115 instruments, and this guitar is #26.


This instrument is superbly crafted and all components and finish are of the
highest quality, the pictures speak for themselves.


This guitar has the original unique GMP body design that was called the
Classic. Subsequent body designs like the "Pawn Shop Special" and the
"Roxie" were more traditional looking.


The guitar's serial number is 26-10/22/90 and it is stamped proto, short for
prototype. I was endorsed by GMP for a short time and this guitar was made
specifically for me and has been in my possession for the last 18 years.
I worked on this prototype with Dave Pearson, he and all the staff at GMP
were very nice and accommodating to me.


What makes it a prototype is that it's the first GMP that had the 2 single
coils, one humbucker pickup configuration. I'm not sure, but it might also be
the first lefty guitar they made and possibly the first with a tremolo unit.


It has a single volume knob, 5 way pick-up selector and a coil split switch
for the humbucker which also makes it unique to other GMPs.


The body and the 24 fret neck are mahogany, the fret board is ebony and the
guitar has a 2 piece quilted maple top hand picked by me with a beautiful
cherry sunburst finish.


The inlays on the neck and the GMP logo on the headstock are abalone shell
also hand picked by me.


The trem is made by Wilkinson and is currently set to dive bomb only, trem
arm is included.


The gears are Sperzel locking tuners.


The neck is straight and the action is low and there's no fret wear.


The guitar originally had Seymour Duncan pickups, but the PUs were changed
several times over the years and it currently has DiMarzio Virtual Vintage
PUs installed.


The 2 original Duncan single coils will be included in the auction, the
Duncan humbucker is long gone.


Also included is the original case, which like the guitar is in excellent
condition.


I took good care of this guitar and besides a little pick swirl and a few
minor surface marks that don't show in the pictures the only visible flaw is
a small chip in the clear coat by the volume knob, which is visible in the photos.


2 of the 4 machine screws that secure the plate that covers the control
cavity are missing, but would be easy to replace."
