Electro-Harmonix Slap-Back Echo
Electro-Harmonix · pedal
The Electro-Harmonix Slap-Back Echo is a dedicated analog slap-back delay pedal offering three fixed delay times — 45ms, 65ms, and 100ms — optimized for rockabilly, country, and early rock and roll single-repeat echo. Controls include Blend (wet/dry mix) and Level (up to 20dB of clean boost), with delay time set by a three-position switch. The 100ms setting delivers classic rockabilly slap; shorter settings produce tighter, drier doubling. A built-in low-pass filter at full wet mix darkens repeats to mimic tape echo rolloff. True bypass.
