Dinosaur Jr. star J. Mascis has called on fans to help him locate a signature guitar that was stolen during a gig in Oregon last week (11Oct12).

The rocker and his band noticed the Squier Jazzmaster axe was missing as they packed up after a show in Eugene, and now Mascis has taken to the group's Facebook.com page to ask for help in tracking the instrument down.

He writes, "Some characteristics that make this guitar unique: there is a dent in the neck, the pickups have no screws as they usually do and the action is currently set high. The guitar was in a soft gig bag."

Mascis has asked fans with any information to contact him at band@dinosaurjr.com.
