Really interesting thread! I just worked out that I will have been playing bass for 25 years next month so below is the list of instruments I've got through between the ages of 14 and (almost) 39. I blame Basschat for forcing me to make the majority of the later purchases here against my pathetically weak will and better instincts.
I feel slightly embarrassed by the amount of gear I've got through in that time but to be honest, looking at some of the other epic lists that this thread has brought to light, it's not that bad! The basses listed in bold are the ones I currently own.
Anyhoo, here goes:
1996: 1995 Ibanez TRB70 bass
My first bass, decent bass for a beginner and looked very slick, got me through my first school bands. Very unreliable pickups with pole prices regularly sinking into the pickup casings!
1999: Fender BG-29 Acoustic Bass
Bought for acoustic jams, very dull sounding acoustic bass and too quiet - pretty useless in hindsight, should have put the cash towards a better electric bass.
2000: Warwick Streamer Standard 5 string
Youthful ignorance compelled me towards this tone deficient shocker in the form of Warwick's (then) newly produced budget Streamer line. Had a B string slack enough to use as a skipping rope. Awful bass.
2003: Music Man StingRay in Pacific Blueburst
My first quality instrument. Absolute beauty!
2008: Fender GB-41SCE Acoustic Bass
Another Fender acoustic... Way better than the BG-29 though, way louder, and the size of a house. Finding a case or gigbag to fit was a bit of a mission.
2008: Music Man StingRay HS
The bass I regret selling the most. An absolute belter - the Jazz pickup coupled with the MM humbucker makes all the difference, but like wearing an anvil across your shoulder. Character building from a gigging perspective!
2014: Fender Aerodyne Jazz Bass
Lovely bass - neck just far too thin for my hands and very prone to bowing, so it got moved on
2015: Bassix EUB
Enthusiasm got the better of me with this one; bought from an extremely shifty American guy on Gumtree, who was about to leave the country. Got it home and realised there was a fault with the electronics and some not-obviously apparent damage to the body that the sneaky f*%£$$ wasn't upfront about.
2016: Stanford Robot Acoustic Bass
Indisputably the best acoustic bass in all aspects in that price range. A very lucky purchase!!
2017: Fender US Geddy Lee Jazz Bass
Awesome! An absolute beast of a bass and has the most amazing neck with a thicker profile that makes it super fast but also more substantial than your usual Jazz neck. Just wish I didn't have to take the neck off every time I need to adjust the truss rod.
2018: Bridge Cetus Electric Double Bass
Lovely bass with a hollow body making it much more comfortable to play than a lot of other EUB type basses - sold hastily and regrettably as a result of repetitive strain injury and sudden change in circumstances.
2020: Ibanez GWB20th 5 string fretless
Bought on a whim to replace the Cetus. The quickest I've ever moved a bass on, owned for just over a month. String spacing was too close for my sausage fingers, ended up being an expensive way to come to the conclusion that fretless bass just ain't my thing. Sold at a serious loss too.
2020: Ibanez TR200 bass 1997
The bass I wanted when I was 15 but couldn't afford, bought in April last year; I've upgraded the bridge, tuners and pickups. Still persevering trying to get on with it, and get a tone I like out of it.
