It would be good if you could have a guitar that you could fill with beer ( wine, whisky or whatever- even Ribena if you feel daring) with a tube that runs up your strap and into your mouth. You wouldn't need a break then ( no more lining up at the bar). There might be a way to put a mini refrigerator in it though I suspect that that might have too much effect on the tone. Also, the motor of the 'fridge might cause a bit of hum. The whammy bar could act as a pump- do a dive bomb, get a shot of booze- hey I am onto something here methinks. I am sure that Ron, Jonathan or Bob will be inspired and customer orders will start flooding in.
