Re: What are the must haves for gigging?
Someone said needle nose pliers. I bring a Swiss army knife with screw drivers, knife and pliers. I also bring a bunch of plastic tie-wraps to keep the kit from moving while playing. Hook up about 8 of the long tie-wraps together going through the bass drum lug and tie it to the thrown. The hi-hats also tend to walk, you can tie the hi-hat to the bass drum and then to the thrown..
Also gain an understanding of how to fix the equipment if broken. Set the kit up, and tune up the kit, before the gig and tear it down and do an inventory. An extra snare chord or plastic is helpful.
I am not here just to keep the beat; I add color, timbre, and presence.
