The Rocktron Vertigo is a stereo tremolo pedal designed to create classic tremolo effects. The pedal features controls for Depth, Rate, and two unique modes: a normal tremolo and a special "dual-mode" that creates a dramatic, panning tremolo effect. It is housed in a durable metal chassis and is suitable for both guitar and bass. The Vertigo utilizes a custom analog tremolo circuit to ensure a wide range of tremolo sounds from subtle to intense.
