Chuck has very specific requirements for his amplifiers. These amps are to be rented for Chuck. They are "riders" in his contract. If the promoter does not provide two Fender Dual Showman Amplifiers, with J.B.L. 15 inch speakers, the promoter is to pay a penalty, over and above the standard fee. This night, the promoter screwed up, and Chuck got a little extra in his pocket.
