Boss SDE-3 Dual Digital Delay

Finely Tuned Digital Engine and the Non-linear Behaviors – The Boss SDE-3 Dual Digital Delay

Introduced in 1983 by our parent company Roland, the SDE-3000 is revered for its beautifully rich sound and distinctive modulation. The coveted SDE tone was realized through a finely tuned digital engine and the non-linear behaviors of the supporting analog circuitry,including magnetic saturation in the anti-alias filter, evolving modulation produced by the components of the time, and an altered triangle LFO shape.
