Now, this one is a keeper!
The sound should be the main factor for defining this guitar, but actually the look and finish are astonishing as well.
Fret Edges Binding and mother of pearl inlays are distinctive features for this model.
Despite numbered as being an '80 instrument, this version is from the late '70, with the original Protomatic-I.
These pickups are exactly behaving as described by a '77 catalog: "Mellow high tone, rich Mid-Range, unique distorsion sound, powerful sustain".
This particular guitar, with wonderful grain.
The finish looks to be nitro........No other details are left to enhance this great piece.
