This bad boy is a 77 j copy with no name on the headstock. It does have a date stamp on the back of the headstock that says "050277". I've had this bass for a while and it has killer vintage vibe. Ive seen these as "Maya" or "CMI". Has a really cool tone and i reallllly like the neck. A buddy of mine has a hot rodded parts bass hes selling, so i need the cash. pm me with any questions. SOLD!
