Featuring military-grade circuitry, streamlined controls of speed one, two and depth as well as dual tremolo settings controlled via footswitch, the BBE Tremor is an optical-based effect designed to emulate '60s Fender amps. Crafted from careful study of vintage tube amps, this pedal allows guitarists to dial in classic tremolo effects at two different rates and easily switch between them. Perfect for classic rock, garage, or surf.
