No but I can buy a spanner for about 50p from Wilko.
I use decent gear and if my bass goes flying at an irritating band member at the previous gig i'll always make sure before leaving for a gig that it's all in good working order so it doesn't let me/my band down at a critical moment. Doesn't mean I don't deserve to have my bass.
