Bag of Tricks

Being a traveling musician, there are endless perils to be discovered waiting for you at a gig. Finding outlets, connecting things in new creative configurations, if you are using an existing sound system, you never know what kind or how many inputs/outputs they will have. This is why it is essential to have a 'bag of tricks' of sorts to take with you.
My bag of tricks is mainly a large assortment of small converter pieces for audio. xlr to rca, rca to quarter inch, eighth inch to quarter inch, male and female adapters of all varieties, so that when the occasion arises, you are ready. I also have a battery or two of various sizes, scissors, tape, a flash light, extra picks, needle nose pliers, strings, marker, and a screw driver.
The band that I was in a few years back had optional video that companioned with our show with textures, music videos, pictures, live video of the crowd, lyrics, and a pre-show countdown, so it was also necessary to include every type of video adapter we might come up against to hook to the computer.
The hard part is creating the kit with everything you'll need the first time...after that you just grab it and go. You'll be suprized how often you need to change things on the fly, even when using your own system.
On a side note, I also put the kit in a professional looking gig case for my own enjoyment. It looks very professional when at a show a problem arises and you pull our a shiny brief case filled with all the stuff you need.
