Professor’s Notes
Classic single-repeat tape echo — the Electro-Harmonix Slap-Back Echo delivers instant vintage bounce and bold rock ’n’ roll attitude. Professor’s Tip: Blend it just below your dry tone — enough to feel it, not hear it. That’s the secret to thicker rhythm tracks without clutter.

Description
The Electro-Harmonix Slap-Back Echo revives the sound of classic tape-style single-repeat delay — the secret sauce behind countless rock, rockabilly, and blues recordings. With a single echo voice, it delivers that immediate, rhythmic bounce that thickens solos and adds dimension to clean and driven tones alike.

Three delay time settings — 65ms, 125ms, and 250ms — offer classic short-delay flavors, while Blend and Gain controls shape the wet/dry balance and add grit or clarity to the repeats. The result: warm, organic reflections that add depth without getting in the way.

True bypass keeps your signal clean when disengaged, and the rugged enclosure ensures it’s ready for life on the road. The Slap-Back Echo doesn’t overthink it — it just nails that timeless, one-repeat magic.
