I have a few basses but only one number one my P. I've always wanted to buy another bass as a equal to my P and bring both to the shows in case one went down. I know it's always better to have it and not need it. Now twenty years later I have never had to rely on a backup to get me through the night. I've seen guitars many times go down but never a bass (besides strings). I know a lot of fellows that have toured the world since the eighties that still own only one bass and that's how they still roll. They all never ran into a problem. I know it would really come in handy if for some forsaken reason your bass was stolen while out on the road or even at a local show on a sat. night. But WHO has some first hand accounts of "Thank god for the back up" moments.
