YAMAHA Electric Bass "RBX550RS Special Edition" This bass was received in the 1990s and was used for live performances and practice, but I haven't had a chance to use it recently, so I'm putting it up for sale. I haven't made any modifications to the parts since I've had it. I'm not very knowledgeable, so I would appreciate it if you could check the images and do your own research. Regarding the operational check, I was able to confirm that sound was produced when connected to a PC via AIF. A soft case is included. Sold as is. Please purchase only if you understand and agree that this is a used and old item. Please refrain from purchasing if you do not understand or are concerned about the condition. Regarding shipping, I will prepare special packing materials, so it will take a little time. I have added images of the included soft case.
