Original brand new BOSS DUAL DIGITAL DELAY SDE-3.

Vintage digital sound for today’s pedalboards
Introduced in 1983, the Roland SDE-3000 is one of the most revered rackmount delay units from the early years of digital audio. Although the SDE-3000 was used in recording studios, its most popular application was in ‘80s-era guitar racks, where its ultra-wide dynamic range, adjustable delay phase, rich modulation, and multiple seconds of clear-yet-warm delay tone made it the go-to digital delay processor. The SDE-3 replicates the sound of the original SDE-3000’s digital processing and the analog nonlinearities to a T, but it ups the ante with two parallel delay lines. This enables the SDE-3 to mimic the functionality of two vintage rackmount SDE-3000s, ostensibly packing the performance of a refrigerator-sized guitar rack into a traditional BOSS stompbox enclosure.

Expanded stereo options and multiple output modes
Aside from its dual discrete delay lines, the BOSS SDE-3 also includes two stereo delay options and multiple output modes, enabling you to tailor it to myriad applications. In Standard mode, this digital delay effects pedal is configured as a typical stereo delay with fully independent A and B channels. Pan mode allows you to alternate the left and right positions of each delay line on each repeat, which infuses your playing with dizzying, spellbinding dimension.

As for output modes, the SDE-3’s default Stereo setting mixes your direct and effected sounds via the Output A and Output B jacks. The Wet + Dry mode outputs your effected sound via Output A and your dry sound via Output B. You also get a Direct Mute mode that outputs only your effected sound via Output A and Output B — a must-have for using the SDE-3 as an auxiliary effect.

Regardless of how you configure the SDE-3, its Offset knob is arguably its most powerful control, enabling you to fine-tune the relative time difference between the parallel delay lines to generate everything from subtle thickening and flam repeats to rhythmic syncopations and ear-grabbing atmospherics.
