Not to start a flame war here. It's just about getting some opinions and thoughts. I am blessed to have owned some of the best instruments, and I owned 15 basses at the same time at some point in my life. Now I'm the lucky owner of a Sadowsky NYC Will Lee 4, a Sadowsky metro MV5, and a Fender Precision bass CS Pino Palladino, so 3 amazing instruments. Except for a band where I'm really asked to bring the 5 string, most of the time I find myself Asking myself which bass to take, knowing that owning the gear I own , whatever bass I take will be ok ( unless they don't want the flatwounds vibe...) But I remember when I only owned one bass ( those days are pre TB) and doing everything with that bass , finding ways to get the tone I want from one bass... I often ask myself if I wouldn't be happier just owning one bass and just do everything I need with one, ok it's cool to have loads of instruments to choose from, but at the same time it's great not to have to think about anything and just grab what you got when you only have one bass, and just play the role of the bass player. I say to myself that owning a great 5 string is all a bass player would need ( of course it's not a 4 and somebody could tell me what about the flatwound tone etc...) I'm a pro bass player, I earn my income playing bass, and of course a pro needs some tools, but sometime, just a great sounding bass is enough, for example, I always have compliments about my tone when I bring one of my Sadowsky basses, or people love the "velvet" tone of my pbass, so whatever bass I bring, I always have a good tone. It's just that sometime, I miss those days where it was simpler, just owning a bass and doing everything with it. If you guys only had to own one bass, would you get a passive bass, active bass? 4 or 5 string? Jbass or Pbass oriented ( or maybe something else like a Musicman or whatever?) for the ones that went back to owning one bass, are you happier?
