Electro-Harmonix Slap-Back Echo Pedal

The late 1970s rarity Electro-Harmonix Slap-Back Echo pedal is reissued with modern updates and a Pico footprint!
- Independent gain and blend knobs
- Time switch with 45ms, 65ms, and 100ms delay times
- Up to 20dB of boost
- True-Bypass
- Small, pico-sized chassis
- 9V power supply included
The 50s era gave birth to an iconic sound in which a single, short delay was utilized to add depth and rhythmic effect on countless recordings. The 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.
Housed 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 also adjusts the overall volume at the output with a boost of up to +20dB. The Blend knob mixes the dry signal and the echo signal from 100% dry to 100% echo. The Time switch selects between three different delay times: 45ms, 65ms, and 100ms.
