I started counting how many basses I have owned. Since I had to pull my shoes off, it must be more than 10.

Here they are in chronological order of purchase with my impressions (YMMV, of course):
Univox Rickenbacker copy - looked great, sounded not so great. Upgraded with EMG pickups (after all, only the pickups really matter on a bass...). Learned that you can't shine sh*t. Traded it in.
Peavey Foundation - a pretty good bass although I could never get past the name on the headstock. That, and the pencil thin neck. Then again, sometimes cheap basses can be just as good as expensive ones. Traded it in.
Steinberger XM2 - sounded good when played with a pick. Otherwise, meh. Also had difficulty with the narrow string spacing. Sometimes expensive, cool looking basses are really not that great. Sold it.
FBass BN4 - Really nice bass. Recently sold it after almost 20 years. The large radius fretboard and small body never really felt comfortable to me, but I can't say anything bad about it.
'66 Fender Precision - Killer bass. I choked on the $1400 price tag at the time but, in hindsight, it was a bargain. I sometimes drift away from it for a while but IMO a good P bass should always be on hand. I've had it for 20 years now and suspect someone will inherit it.
'77 Stingray - Well, a pre EB Stingray has to be the shizz, right? Wrong. Maybe it was a bad one or maybe it just didn't suit me. Sounded great in the store but on a gig, I just couldn't get a tone I liked out of it. Sold it.
'96 Sadowsky Jazz - Funny story - I went to a music store looking for a Geddy Lee jazz. Found one I liked but couldn't get the attention of anybody in the store to answer my questions. Got pi$$ed off and went down the road to a small shop where I found this used Sadowsky. If it wasn't for the downsized body and 12" radius board I would still have that one. Sold it.
Sadowsky UV70 Metro, Sadowsky NYC UV, Sadowsky RJ4 Tokyo - Yup, three in a row. The Tokyo and UV70 have identical specs (Ash, maple, single coils, 70's spacing) and sound completely different. The UV is really aggressive sounding while the Tokyo has got more of a round 70's jazz "thud" that sounds really great when slapped or played finger style. The full size body and smaller radius board on these basses feel really comfy to me. And the tone.... Still own all three.
Late 80's G&L SB-1 - cool bass. REALLY hot pickups. Dial it back a shade on the volume and it sounded just like a good P Bass. I wasn't so keen on the small body and light weight of the bass although the tone was great.
My bass instructor complained that he couldn't find a good P Bass that was light weight (he is a small guy and quite elderly). I strung the bass with TI flats (his favourite) and gave the bass to him. The look on his face was priceless.
'77 Precision Bass - unlike the '66, this one is Ash/maple. Oh, and it weighs 10.5 pounds. It has the P vibe but has a much more "compressed" tone that sounds great banging out eighth notes with a pick. Still have this one.
There you have it - every bass I ever owned. If anybody is considering purchasing one of these, feel free to PM me for an opinion.
