Some absolute, cheap, no-name bass that someone had painted black (not a Teisco or Silvertone, not that high-end!). I think I paid $10 for it (around 1971 or 72). It was pretty bad, I'm sure, but..... it was good enough to get me started playing bass, after spending 5 years trying and failing to get good at guitar. Soon after, I graduated to a Fender Musicmaster, then an EB-0, then a Rick 4001. After playing bass for several years, and getting pretty good at it, I went back to guitar, and it came a lot more easily - even played rhythm and some lead(and bass, of course) in a classic rock band about 10 years later. What goes around, comes around!
