I learnd my lesson years ago with keeping a glass or bottle next to me on stage after I knocked a drink over onto my Korg 13 'YIKES" so now I use a type of cup holder that you use in your Vehicle, it hangs on your car window (plastic) only thing I hang it on my Gig Box next to me on an X stand. Its safe, convienent, and strong. Cost $1.00 US.
