The '50s invented a single, short delay to create an iconic sound that added depth and rhythmic impact to countless recordings. The reimagined EHX Slap-Back Echo's all-analog design delivers beloved classic sounds and more in a pedalboard-friendly pico-sized package. With three delay time settings and up to +20dB of gain, Slap-Back Echo can achieve subtle doubling effects for harsh reverb reflections, all with the distinct flavor of bucket-brigade circuitry (BBD). The Slap-Back Echo is housed in his EHX's pico-sized housing and features gain and blend controls and a time switch. The gain knob controls the input signal before the echo circuit and also adjusts the overall volume of the output up to +20 dB. The Blend knob mixes the dry and echo signals from 100% dry to 100% echo. The timer has three different delay times to choose from: 45 ms, 65 ms, and 100 ms.
