First Look: Ernie Ball Expression Tremolo

It’s easy to characterize Chase Bliss' Joel Korte and “Analog” Mike Piera as pedal-designer opposites. Piera’s work is rooted in understanding what makes great vintage circuits special and building improved, refined, better-quality versions. Korte is often a maximalist (many sounds, many knobs, many possibilities) and an envelope-stretching modernist (unorthodox tones, digital control). But the two builders share much in common. Both are gifted designers, and each is tireless—perhaps obsessive—about chasing specific sounds. The intersections in their methodologies are embodied in the Brothers AM, a Chase Bliss/Analog Man collaboration based on the scarce and much-coveted Analog Man King of Tone dual-gain device.
