My gig bag is that box-with-a-lid thingy in the guitar case that is kinda attached to the U groove that supports the neck. If I am gonna stay overnight, I use underwear, socks and a t-shirt to fit where they can. In the box thingy which I have just perused goes extra picks of varying bendablenesses, capo, tuner, strings, Fast fret, an old shopping list with cashews underlined three times, bottle neck, string winder and wire cutters (snips).
