I'm sure this has been asked many times but please indulge me anyway: Somebody asked which bass you have GAS for and I said a custom-built Alembic. It occurred to me, though, that I really don't know what all I would want on a bass and how I would design it or whom I would have doing the work. I see some people are here are in fact building their own, which is great. SO, with that in mind, if you could custom-build your own bass from scratch and money was no object (filthy rich as we bass-players generally are), what specs would you want? (e.g. pups, pots, electronix, woods, tuners, bolt-on or neck-thru, fingerboard, fretted or unfretted (lined, unlined), body design, scale length, how many strings, bridge, weight, 4-in-line or 2+2 or other, etc. Also please provide reasons why you want those particular features as opposed to others (i.e. better slapping ability, deeper sound, easier string action, minimizing deadspots, etc.). And whom would you hire to do the work? This is your chance to get it out of your system, folks, so just let your fertile bass-obsessed imaginations run wild. Go all out and build the "America's Castles" of basses! PS - I'm going to lay one restriction just to make it interesting: you can only build one.
