The late 1970s rarity Electro Harmonix Slap-Back Echo Analog Delay Reissue Guitar Pedal is reissued with modern updates and a Pico footprint. The 50s era gave birth to an iconic sound in which a single, short delay was utilized to add depth and rhythmic effect to countless recordings.DesignThe newly reissued all-analog design of the EHX Slap-Back Echo delivers this beloved classic sound and more in a Pico-sized pedalboard-friendly package. With three delay time settings and up to +20dB of boost, the Slap-Back Echo can achieve subtle doubling effects to intense bathroom reflections all with the distinct flavor of bucket-brigade (BBD) circuitry.MechanismHoused in EHX’s Pico-sized chassis, the Slap-Back Echo features Gain and Blend knobs as well as a Time switch. The Gain knob controls the input signal before the echo circuit and adjusts the overall output volume with a boost of up to +20dB. The Blend knob mixes the dry and echo signals from 100 percent dry to 100 percent echo. The Time switch selects between three different delay times: 45ms, 65ms, and 100ms.
