"We used a whole lot of things. We used Randall amps and I used six cabinets, 13 mikes and four channels. I don't exactly what Geof did, but he cued it in a certain way to make it sound like that," said George.

One of the amps George experimented with was the Seymour Duncan Convertible head. This 100-watt amp featured tube "modules" formulated to create different preamp tones by placing them in different combinations and different orders inside the amp's chasis. Several prototype modules were made for certain players. They even made one for George.
