the musicman sterling is a high end model, in this case the same style as the sterling by musicman SB14, it has a smaller body and a more skinny neck, and sounds very very similar. The ray 34 has a fairly chunky body and a neck similar to that of a p-bass. the SUB bass is more like an actual musicman stingray than an SBMM ray 34 as it's made in the USA with actual musicman componentry but cheaper wood and paint jobs. Very nice basses, i used to have one, but i didn't get on with the neck, very precision-like.
