Let me qualify "the one" by defining it as a bass that meets your needs and preferences so well, that finding another that fits you as well is very statistically improbable. So who has this instrument.....loves it to pieces....yet still snoops around for something new? If you're a "need a bag of golf clubs" person, i.e. different tools for different situations, clearly this won't apply to you. But if you're a hobbyist that is really happiest playing said "one", I'd be interested to know whether you still search. EDIT: If you have a "one", then please tell us what it is!
