Most of us know this is just an excuse to own another bass. In all the years I've been playing, I've never had a bass crap out on me, although there was that time I ran over one with my car.....twice. Anyway, the question is; if you have, or want a back-up axe what is it (or what will it be) and why? Currently, my back-up bass is a Westone Rail. The reason is that it was relatively inexpensive, has a nice warm "Funk" sound, is very small and light weight (easy of transportation), and the radical design is a real eye catcher.
