The Electro-Harmonix Slap-Back Echo takes a 1970s-era EHX rarity and reissues it in a convenient pico-sized stompbox. Armed with analog bucket brigade circuitry, this pedal produces everything from subtle doubling to Sun Records-style slapback. The Slap-Back Echo includes a 3-way Time switch with 45ms, 65ms, and 100ms settings, along with a Blend knob for dialing in your mix of the wet and dry signal. You also get a Gain knob that supplies you up to +20dB of boost. Complete with vintage-inspired graphics, this analog delay pedal boasts true-bypass switching and comes with a 9V power supply. Whether you're dreaming of intense bathroom reflections or you want to get your rockabilly on, you'll love the distinct flavor of EHX's Slap-Back Echo
