The Frank amp-n-stein was PG's first special edition amplifier. It consisted of an MS2125 and an MQ430 in the same heatsink. The heatsink was powder coated black with a purple glitter clear coat. We also included an AX406a 3-way crossover with matching color scheme. The set was shipped in a "body bag" packed in a wooden "coffin" crate with straw. The original retail price was $2500 for the amp and $300 for the crossover. These amplifiers have become the most sought after amplifiers PG has ever produced.
