Well, let me look and see. Okay, I am back. Here goes:
1. tuner with spare batteries for both tuner and my active basses (when I use one)
2. strap
3. Monster Cable
4. cleaning and wiping cloth
5. a couple of picks (I rarely use one, but they come in handy when you hurt some of your fingers or it is requested for a song)
6. a set of pre-cut strings in case one breaks

7. pencil/pad for notes
8. XLR matching box just in case I need to directly go into the system or my amp dies

(has never happened, but be prepared)
9. XLR chord
Besides the normal stuff above, these things have been found in my bag or case from time to time:
1. lunch, dinner, or a snack
2. music scores & sheets
3. something to read during down time
4. effects pedal(s) with appropriate chords
5. map
6. guitool
7. a copy of a chart which includes a wheel of fifths, number of flats and sharps chart for key recognition, major and minor chords for each key.
8. small first aid kit or bandaids
