Scored this off evilBay. MIJ RI Fender Mustang bass. Lake Placid blue is very rare on these models, in fact it is only available by custom order. Serial dates it to 2004/2005.
I have always played p-basses, so the ultra thin neck and short scale will take some getting used to. Sounds very similar to a p, but a little "rounder". Needs some new foam behind the pickups and maybe a tortoise shell pick guard. Other than that, I'm keeping it stock. Loving it so far.
