"Have you ever experimented with a different bass in AC/DC?
I played a Fender Precision for a little while, when I originally joined the band. Then—what is that little headless graphite bass that looks like a toothpick? Steinberger. Those were the first active pickups I ever used, and I really liked the sound, but I hated the bass. I played it on the road for a while, but I just couldn’t stand the shape, so
I pulled the guts out of it and dropped them into the P-Bass, which wasn’t bad. I’ve also fiddled around with a Fender Jazz over the years and a Gibson Thunderbird as well, but not for very long. I always seem to go back to the Music Man."
