I play for a church and I switch between bass (my main instrument) and acoustic guitar (my backup), I own 3 basses (2 electric and 1 electro-acoustic) and 4 guitars (2 electric, 1 acoustic and 1 electro-acoustic) and a cajon. I always thought of myself as a bassist but now that I own more guitars than basses and I play more acoustic guitar in church than I play bass, I now simply think of myself as a musician.
There are kids in our church Worship Team that play multiple instruments and put most adults to shame, one plays drums, bass, keyboards and flute.
If you fancy playing something, have a go, give it a try and embrace music as a whole.
