I received this bass as a christmas gift when i was 12 yrs old. i never touched it until years later. my dad bought it for me from a music store that was going out of business. I can't find any solid information for this guitar online. the headstock reads OLP for officially licensed product and the back of the headstock says Traben. Does anyone know anything about this? any information is helpful :]

OLP TB4. OLP were a company that makes licensed instruments. They used to do Musicman replicas as well as a model in conjunction with Orange County Choppers. They don't exist anymore. Most likely a basswood body like the majority of the OLP line, with maple neck and rosewood fingerboard.
thank you! i've tried so hard to find information on this guitar and i'm glad to be finally helped out.
