Sad, yet true. Unfortunately I can also see you putting ‘please look out for xxxxxxx, serial number yyyyyyy’ posts on here when stuff worth more than the deposit doesn’t find its way home.I wouldn't rent any gear you're particularly attached to. While it would be nice to think every renter would treat the gear with respect, I would not place a large bet on that happening. There are a lot of people in this world who have no problem abusing equipment and gear that doesn't belong to them.
I think your best bet is to work with the recording studios that you are aware of. Most studios have their own equipment but if you got your list out you might get rentals from even well-equipped studios. Good luck!
I think you can get backline rentals in most cities.I lived in Park City Utah and our concert people would rent stuff all the time.It'd be a stretch in your location.
I've seen it work in major cities where the gear is rented out to studios, or to touring musicians (backline rentals.)
In the two cases where I've seen it locally, it was mainly amp rentals offered by the same outfits that were offering lighting and PA rentals... and both also offered expert tech services, so they could repair anything that was broken while out on rental. For that, you'd also want to invest in some Twins, Deluxe Reverbs, HRDs, Marshalls and Voxes... backlines that touring musicians typically work with.
