I played guitar first, moving heavily to 7 string around 2012. I was fairly decent, but ended up taking about a 4 year hiatus from music. When I moved to Daytona, I decided to get back into it. Thing is, you could throw a rock and hit 6 guitarist around here, but bassist are pretty rare. I remembered how much I really enjoyed playing the bass, and took advantage of the low market demand driving bass guitars and equipment prices down to build up a nice rig for a small investment (I think my bass + amp + cabs together cost about half of what I had just in pedals when guitar was my focus).
It's a different instrument with similar knowledge, but bass really has me thinking much more creatively about how I approach my playing.
