I recently had a lower back injury and will need to lighten up my bass weight considerably. I messed around on a new Steinberger 4 string and it was sweet. So incredibly light and it sounded pretty nice. My back was very happy and can't deal with my heavy SX J bass anymore. Anyone have any opinions (pro or con) on these Steinberger basses from MusicYo.com? That's the only place I've found to get them. There is even a 5 string that I'm considering. The price is right.
