1. Lyle bass. Looked like a Gibson 335. Right handed, played lefty. Soon restrung it to be like a lefty -- and correctly intonated, since it had a floating bridge. Carried around in chipboard guitar case. Never sounded very good, but the semi-hollow body could be made to feed back, which was something.
2. Rickenbacker 4001 (Left-handed). Now THAT's a bass.
3. Old no-name cheapo, left over from the 60s, given by co-worker. Tore up converting to lefty five-string fretless, but learned to play fretless on it.
4. Peavey something or other, fretless. But right-handed, so played upside down, strung lefty.
5. Yamaha BB350 (Left-handed). OK bass for price; I upgraded the pickups and tuners, much better.
6. ESP Ltd B204SM (Left-handed). Solid body, active electronics. Ordered it fretless but Sam Ash sent regular one by mistake. Fretless out of stock, so they offered 10% discount to keep it. I did, then bought a fret puller and pulled the frets from the Yamaha -- *after* watching some YT vids, so I did it correctly.
7. cheap black lefty 5-string (the one in my avatar). Given to me by fellow church member. Gave away to stranger on FB whose 5-string lefty bass had been stolen. He was delighted.
8. Dean acoustic bass (left-handed). Yes, it's sh*te as an instrument (I had to replace the tuners entirely) but surprisingly handy for instant noodling. Strung with flatwounds so it almost sounds like it has character.
Confession: I haven't been focused on playing bass for several years, but am now heavily favoring (left-handed) Epiphone Jack Casady bass as next gear purchase.
