The oldest bass I own is a '79 model which is coincidentally my birth year, and I've owned it since around '97. The bass I've owned the most is I think an early-mid '80s one, and I've owned it since around '96 which means for 27 years as of now. It was my main bass for a long time when I was a full-time. It traveled with me a lot too. I want to sell it, but my brother won't let me do it.
