Would ideally love to find a decent shape Fender Standard Fretless Jazz bass in Sunburst.

All other brands considered, but it has to be a fretless.

Not looking to spend tons since I can always pickup a brand new one for $600. I'm not good enough to be able to use all the power of a $2k signature series or anything.

Got one hanging around that you don't use? Hit me up, we may be able to make a mutually agreeable arrangement.
