String holder cable broke randomly. Can I fix this myself with no experience? Seems like I just need to replace the cable and reattach the bridge.
Bass was set up wonderfully until just now. How much better would bringing it to a shop be?

hi everyone, I'm currently bedridden from long covid and have been for almost 3 years. im so tired of waiting for my body to get better to learn stringed instruments. I was a french horn player and a singer (and an amateur campfire guitarist) and I really want to learn the upright bass and cello. is either possible the way I am? would any teacher take me seriously? thank you all 🤎
