I am looking at this bass to buy, but I dont know alot about them. Its a Rickenbacker and the serial number is PG 4916. From what I can find its was made in July of 76. Its blonde and looks like its been taken care of. The neck is perfectly straight and it looks like its just missing the cover over the one pickup. The asking price is $1000. Thoughts/Comments? Does anyone know much about these? Thanks!
