Well, I'm certainly biased toward the piano, since I'm technically a piano professor.... But there was a time in my youth where I wanted to be the next Jaco Pastorius and spent more time on the electric bass than anything else. It was honestly insanely valuable for my aural development, and I'd recommend for anybody on this forum to buy an inexpensive (but decent) electric bass and try to learn to play along with a few rock or blues albums by ear. Few instruments give as clear, intuitive, and visceral a map of intervals as the bass, in my opinion.Learning a rhythm section double is a great idea - piano being the best. I’ve ended up playing more jazz gigs as a guitarist, than as a saxophonist of late.
