In our "poorer days" (can't say I've ever known anyone destitute in U.S.A)....we made good use of the white-plastic-clorox-bleach-bottles....flexible, cheap, and easily shaped to your needs...with ridge at the top....then places like McCabe's and the Guitar Institute began having large fish-bowls where you could grab a handful, or a need full....but they were stiff awkward mechanical things lacking the upward-flex-control given to the clorox-bottle which could be stiffend and soften at will by the flex of a fore-finger....time is too valuable now....audience's don't know the diff....a clorox-riff...is only identifiable amongst old friends who know and appreciate....so pay 2.50 and pretend it has a bend.

Sincerely,
Gargoyle
