This is definitely a YMMV topic, but I fall in the camp of owning significantly more than one bass. Sometimes friends/bandmates find it cool, but every so often I pull out a different bass or try something with a different one and I get the "eye roll" from someone. Same old song and dance, if it works for you go with it, but I just want to elaborate on why I choose to own as many basses as I do...which is 7. - I love the versatility it offers me. I don't have to freak out if I want to try flats on a bass, I've got several others that can get the job done that sound different. I'd call it more of a "safety blanket" for me, I know I've got something that can get the job done. Any of them can work, but it just makes me feel more confident when I know a P-bass will fit best and I've got one in hand. - I've got more backups than I know what to do with! My 5-string aside, I've got several basses in case one goes kaput. Strategically have basses that are passive or can run passive as well (in case batteries are short supply). If the gig isn't gelling well with the bass I have, I can try another one later until something works out. - Believe it or not, it actually reduces GAS for me. With the variety I have, I can get many of the common sounds needed or ones that I really like. I can generally get in the ballpark of tones I want within reason. That Wal Mach III is still eluding me, but maybe if I end up stupid rich I'll get one lol. - Getting in the "vibe" of certain music is easier for me when I have a bass that inspires me. Picking up the 50's P I have gets me stoked to play Motown, 60's, or even classic rock or blues music. My mindset changes with that bass in my hands, helps me focus on conveying that vibe to others as I play. My Matt Freeman P is just pure punk, I can't resist banging away at it with a solid pick and some grindy amp tone. - Inspiration might come as a surprise, but just as the basses get me in the vibe of certain genres, a different bass can take my mind other places when I write. Maybe it's the tone or feel, but my Ibanez 5'er takes me different places than my Matt Freeman P does. What draws you guys to owning more than one bass? - VT
The same reason I have different golf clubs, different fishing poles, damn I even have different beers in my fridge.
I currently have 4, including one parts bass that isn't particularly great quality, and one that my brother in law is having for Christmas. So 2 that I'd actually take out. Ultimately, 95% of the time I practice at home, rehearse with the band and gig, it's with one bass. The other is solely a backup, really. I have seen another one locally that I'm tempted by, though.. if I could justify it, I'd probably have 10 plus

I have two basses and that's enough for me. I have fairly narrow parameters of what I like when it comes to a bass: four strings, passive, no more than 3 knobs, 20 frets, P-shaped body, doesn't have to be Fender but they are preferred. I don't get GAS for a bass too often. Amps and Pedals on the other hand...
Mob mentality. Becoming good friends with a collector. The transition of musical instrument marketing from musician's tool to lifestyle accessory. The internet making it easier to locate instruments to buy. Freedom to spend money. I could survive with two: one P and one upright. I'd be very comfortable with four, two of each. Beyond that it's want rather than need, pure and simple.
I can relate to what you are saying about different basses and different inspirations. Sometimes, things just fit! I only have 6, but that number will increase pretty soon. I seriously reccommend you check out the BHPD thread, but be warned, you will never be the same
Currently have 4. My Washburn is mediocre at best, and doesn't have much use - I couldn't go to a recording session with it, for sure. I suppose I could kick it out live or something maybe. One is my Peavey 6 which is a decent backup, but needs new pickups and a preamp. One is my punkified frankenbass thing which is covered in stickers - it's good for punk rock, basically. Again, not session stuff. My main bass is my Warwick 6 which I use for session work, my main band and recording.
I only have one but that's because I'm a guitar player who only took up bass a few months ago. I definitely plan on getting one or two more in the future.
