The [Mr. Black JDD-3000+] is a digital delay pedal that recreates the KORG SDD-3000, a rackmount digital delay that Delicious Audio calls one of the most sought-after digital delays of its era1. The original SDD-3000 was a much-used effect, not just by the Edge but by Daniel Lanois and other bands, both live and in recording studios, according to MusicRadar2. The JDD-3000+ puts that sound in a pedal, with up to 850mS of delay and a few additions of its own, including an optional tap-tempo input and trailing echoes on bypass1.
The original it recreates
The Mr. Black JDD-3000+ is a digital delay that takes its inspiration from a legendary rack unit, and Mr. Black describes it as delivering "the best digital echo tones available from its legendary inspiration," with up to 850mS of delay1. It was a limited edition run of only 56 units, and while it is no longer in production, some lightly used units may still be found on Reverb.com1. Tonebox has a page on the original Korg SDD-3000 if you want the full story of the circuit behind it.
What the JDD-3000+ adds
Delicious Audio describes the JDD-3000+ as delivering the best digital echo tones available from its legendary inspiration1. Two features set it apart from a straight recreation:
- Optional tap tempo: an input that accepts a normally open momentary footswitch, such as the Mr. Black Tap-Exp, so you can sync delay time to the song from a second switch on the floor1
- Trailing echoes on bypass: when you switch the pedal off, the repeats already in motion continue to fade out naturally instead of stopping dead1
The JDD-3000+ also has a sibling in the Mr. Black line: Delicious Audio calls the earlier [JDD-3000] its little brother, with the JDD-3000+ positioned as the fuller-featured version of the two1.
Power and setup
The pedal runs on industry standard 9VDC power through a 2.1mm negative center-pin connector, drawing a maximum of 68mA1. That is within reach of most pedalboard power supplies, but check that the output you plan to use can supply at least 68mA. A power supply is not included with the pedal1.
The JDD-3000+ was a limited edition of only 56 units1. It is no longer in production, and Delicious Audio notes that you may be able to find some hardly used units on Reverb.com1.
What reviewers said
Coverage of the JDD-3000+ comes from Delicious Audio's product page, where Paolo De Gregorio documents the pedal's specifications, its limited run of 56, and its features1. For the original circuit's reputation, MusicRadar's 2014 piece on the SDD-3000 describes it as a much-used effect among touring and studio players2.
Where it sits
If you are exploring delay pedals in this territory, the JDD-3000+ belongs to a family of Mr. Black delay designs, including the Mr. Black Black LTD. Digi-Delay and the Mr. Black Ambience Echoverb. For the wider picture, see the Delay Pedals page.

Questions
Is the Mr. Black JDD-3000+ based on the KORG SDD-3000?
Yes. Delicious Audio describes the JDD-3000+ as a pedal that recreates the KORG SDD-3000, a rackmount digital delay from the early 1980s that was used live and in studios by players including the Edge and Daniel Lanois. The JDD-3000+ is a compact pedal version of that circuit, and Mr. Black also made a related JDD-3000, which Delicious Audio calls the JDD-3000+'s little brother.
Does the JDD-3000+ have tap tempo?
Not on the pedal itself. The JDD-3000+ has an optional tap-tempo input that works with a normally open momentary footswitch, such as the Mr. Black Tap-Exp. You plug the switch into the pedal's tap input to set the delay time in tempo.
Does the JDD-3000+ come with a power supply?
No. Delicious Audio's product page notes that a power supply is not included. The pedal runs on industry standard 9VDC power through a 2.1mm negative center-pin connector, with a maximum current draw of 68mA, so a standard pedalboard supply that can supply at least 68mA on one output will run it.
How long is the maximum delay time on the JDD-3000+?
850 milliseconds. Delicious Audio describes the pedal as delivering up to 850mS of pristine delay, which covers the range of short slapback through longer echo repeats.
Does the JDD-3000+ keep echoes going when bypassed?
Yes. The pedal has trailing echoes on bypass, meaning the repeats already in flight continue and fade naturally after you switch the effect off, rather than cutting off abruptly.
How many JDD-3000+ pedals were made?
56. Delicious Audio documents the JDD-3000+ as a limited edition run of 56 pedals. Because the run was small, the pedal is no longer in production, though some units may be found used on Reverb.com.
