This guitar is the #001 artist proof.This runs are made and given to artist for being tested before Gibson start to manufacture the model run.This one is the vos custom shop inspired by robby Kriegger 1968 sg.The artist proofs, pilot run, prototype,and this no numbered series of artist or special models often are given to the artist to play and check them, so probably this one has been played by Robby himself.The guitar plays and sound incredibly.It's light, rounded neck and a push pull in the treble tone to get the pickups out of phase in the middle position.The guitar is very clean and comes with coa and the Gibson Custom Shop sg case with the golden signature of kriegger
