I always wanted to start a musical instrument library. I loved working in a music store, helping people pick out the right instruments for what they're trying to accomplish, but always constrained by their budget. We had a per-semester rental program for school band students, where we'd take a deposit and rental fees but we'd handle the maintenance and families could save a ton versus buying. Something similar where like, you want to loan out a particular amp or pedal or synth or cymbal or something to go record a record for a week, the library would be there to help you access gear you couldn't normally afford, and I'd be there to keep everything working and help you find the right tool for the job.

Maybe someday.
