1 Rockwithdave 4 years ago Just yesterday i picked up a jet from a used guitar shop in Portland Oregon and I am having a hard time finding any information about it. Seems to be somewhat of a rarity. Can't even find a picture of it online. I do know that there are a handful of upgrades that have been done to the guitar. There is no serial number anywhere not in the cavities or on the headstock. Any ideas?
