Maybe... the idea that things WILL, not MIGHT go bad is pretty paranoid. If it's true I guess I'm way overdue.
I've never got the reputation of being a guy who had to quit the gig in the middle and drive home either. If my bass is in any way questionable I don't take it. I take one I trust implicitily. If I know a knob was a little loose or a jack made a slight noise or the bass sounds different than normal, I either check it out or leave it home and check it out later.
Of course I'm staring fate in the face, just begging for a problem

. If I have one I'll be sure and let you guys know. In the meantime I'll rely on my skills at keeping my gear in top working order and not hoping for the best.
That reminds me, I did have one gig back in the 80's where I had bought a new Washburn 6 string and the scarf jojnt on the neck separated when I took it out of the case. I had another bass with me because the Washburn was an unknown gig-wise. That's when I'll definitely take a spare again.
