I play bass in a couple of bands. My 50’s rock band had a gig last night. In the 90’s, before I became a bass player, I figured synths would replace the guitar. I also thought they would replace the piano.
However, I learned a few things about piano players when I discussed it with them. And I learned a few things about guitar and bass players when I became one. It’s not exactly like this, but it’s in this vein: guitars were not killed by synths (nor were pianos) for the same reason recorded music didn’t kill live music.
Nothin’ like strappin’ on one my strats and jammin’. The only button I care about is the one that goes to 11.:>)
