Rickenbacker 4001 bass guitar, serial number dates to 1981 so probably one of the last 4001 made before full transition to the 4003. This is an extremely rare model having left the factory with all the Black Trim options, being black plastics and black binding on a Jetglo (black) body. In good condition generally, but shows some buckle rash to the back as shown in images. Plenty of life left in frets. The Rick o Sound box is included allowing output to be sent two two separate amps or channels. This has served me well for over twenty years but the time has come to move it on. Images form part of description, ask any questions and inspection welcome.
