signed by both Joe Satriani and Donnie Hunt. The Donnie Hunt signature is on the neck heel, as part of the artwork. This guitar is in awesome condition (Purchased new and played and handled carefully). I have no info on the headstock, it is blank on the back, it doesn't appear to be lazer sculpted, it's seems very stock. The neck joint backplate has the serial number and "7101 Case Ave, North Hollywood, CA 91605 U.S.A." I also took the spring plate off and found a "#62" painted in the cavity. There is some discoloration on the bezel surrounds for the pickups.
