I've been wanting to go fretless for a while now and finally have the money (about $600 USD). The thing is, I also want to have a good fretted bass as a backup or for certain situations. Here are my options as I see it right now: Install a Warmoth fretless neck on my Jazz and buy a MIM P-bass Deluxe (the one with PJ setup) or Get a fretless MIM Jazz (or comparable fretless) and modify it with new electronics and such. I just haven't been able to make up my mind about this and I've been seriously GASing for a fretless for about a month now. Thanks for the help.
