Independent shopping perspective
The Korena take
The SDE-3 places two independently controlled digital delay lines in a compact floor pedal. Time, feedback, level, depth, and high-cut adjustment let you shape each delay, while mono operation offers series or parallel routing. Stereo systems add parallel, serial, ping pong, and cross-feedback choices. The Carryover switch can feed one delay into the other for cascading repeats. Stereo I/O, MIDI input, and the CTL/EXP connection make it a practical option for rigs that need external control alongside flexible delay routing.
Strong match
Who this is for
- Mono pedalboards using two delays in series or parallel for layered repeat patterns.
- Stereo rigs that need ping pong, cross-feedback, parallel, or serial delay routing.
- Players using MIDI or a compatible expression pedal for external delay control.
