My nephew brought a Yamaha RBX170EW over and asked if I could get it to playing condition. My sister was over the previous night and told me about it and I knew it was going to be a full restoration project when she told me who gave it to him. She only mentioned that it had no strings but failed to tell me about the rust. But he really seemed like he wanted to play bass, he has played a viola for about 6 years now though middle and high school. So I think he’s ready and at least the body and neck are good.
