This is a black 4 string Yamaha RBX170 for sale. It was my backup bass, and has seen very little play, but has been well taken care of. No body damage aside from a very small ding in the front that isn't noticeable. It has a passive pickup system, action is great, and has excellent tone. It's super clean. If interested, I can send more photos. Feel free to contact me anytime. Please only serious buyers.
