wristband...lolI've never had an amp or a bass fail at a show... knock on wood. I have had batteries and cables fail miserably a number of times so I carry extra cables and don't rely on batteries. Straps though... One of those failures that sucks more than anything. Happened once and won't happen again. I've also forgotten my wristband (I've worn one for 20 years), which made for a crappy playing night.
i once forgot my strap, and i ended up having to take the shoelaces out of my sneakers. my shoulder hurt for 4 days after that gig. so yeah, i bring an extra strap in my gig bag at all times. small items i don't mind redundancy. big items...nah.
