First bass was a 1980's Peavey T-45. I hated that thing. But I also learned a lot playing that bass.
My main current bass is a 1994 Pedulla Thunderbass. So I've basically gone from starting out with a big, heavy, ugly, passive, dull sounding bass to a much more modern, sleek, small-bodied bass with modern sounding Bartolini soapbars and a Bartolini pre-amp. It's been a long journey.
On a side note, it just goes to show you how unimportant your first bass really is and why I don't understand why so many people spend so much time trying to figure out which "first" bass to buy. What you start out on isn't likely to be what you are playing 10 (or however many) years later.
