I have a MIJ Fender Sting Precision bass that I absolutely adore, perhaps even more than vintage Jazz and P basses that I own that are much more valuable. I just put TI flats on it and it's a match made in heaven. Now I'm thinking I grab another "just in case something happens" to the first one. I do this sometimes with other things, usually clothes. Though I used to do it with hard-to-find vinyl records as well. It's some part pragmatism and some part pathology. To date, I have never lost a bass guitar, or had it stolen or destroyed in a fire. The chances of anything "happening" to my beloved bass are next to zero. And yet the voice in my head says "yeah but if anything did happen, it would be hard to track down another." Also, I'm generally not someone with a GAS problem, as far as I can tell. I'm not into collecting instruments or gear. My main instrument these days is acoustic bass and I'd never dream of having an identical backup. No room and I don't have several thousand extra dollars lying around. Do others suffer from this delusion that we need a backup in case lightning strikes?
