The Mr Black LTD Digi-Delay is a digital delay pedal from Mr Black, the Portland, Oregon builder known for time-based effects. It offers up to 900ms of delay time, which Mr Black describes as "crisp and articulate repeats with just a hint of subtle modulation that only shows itself when desired"1. It was a Jack Deville original design produced in a limited run, announced in July 2016 and marked sold out on 28 July 201612.
The LTD Digi-Delay was a limited run and sold out on 28 July 2016, roughly three weeks after launch13. It is no longer available new.
What it does and how it sounds
The pedal delivers up to 900ms of digital delay1. Mr Black's own description of the repeats is "crisp and articulate," with a subtle modulation character that stays out of the way until you push for it1. Gearnews noted the maker's claim that all 900ms are "crisp and articulate"2.
MusicRadar reported that the pedal promises a highly tuned frequency response with a slight top-end roll off and low-end cut3. That voiced repeat path is a common approach in digital delays, shaping the echoes so they sit behind the dry signal rather than stacking up harshly.
Mr Black also highlights self-oscillation on demand, and says the pedal is excellent on bass and baritone guitars1. Self-oscillation means the feedback loop can be driven into runaway repeats, the way vintage tape and analog echo units do when pushed.
Controls and power
Gearnews described the control set plainly: "The unit has Level, Time and Regen controls, which are all self-explanatory"2.
| Control | What it does |
|---|---|
| Level | Repeat volume |
| Time | Delay length, up to 900ms1 |
| Regen | Feedback, from single repeats to self-oscillation1 |
The pedal is true bypass and runs from a 9V DC power supply or a battery2. No current draw figure was published.
Where it came from
Mr Black pedals are based in Portland, Oregon, and Jack Deville designs the company's delay, reverb and other time-based effects2. The LTD Digi-Delay came out of what Mr Black calls a simple concept that "morphed into the perfect digital delay"1. MusicRadar framed the launch with the question of whether Mr Black had created the perfect digital delay pedal, noting the builder's track record with ambience effects3.
The pedal was announced in early July 2016 and priced at $179.95 USD plus shipping and taxes2. MusicRadar's launch coverage gave the price as $1793; the maker's regular price was $179.951. The run sold out on 28 July 20161.
What reviewers said
Gearnews' reviewer was positive about the sound from the available demos, while noting the limits of judging from clips alone2:
"There are a couple of audio demos on the Mr Black site and they do sound rather good to my ear. But you can never tell u"
The same reviewer, who owns Mr Black pedals, called them "bloody good"2. Gearnews also regretted the limited production: "The LTD Digi-Delay is produced in limited run which is a pity, really"2.
Where it sits among Mr Black delays
The LTD Digi-Delay was one of several delay designs from the builder. Mr Black had earlier announced the Ambience Echoverb, a multi-tap delay and reverb pedal, in October 2015, and the TrancePortal shimmer echo in May 2016. Later limited runs included the JDD-3000+, a recreation of the KORG SDD-3000, and the DoubleTracker Stereo in 2024.
A separate note on the name: TONEHOME documents a Lemon Studiosound Digi Delay, a different product whose delay times reach almost 4 seconds4. That unit is not the Mr Black pedal, despite the similar name.
Questions
Is the Mr Black LTD Digi-Delay true bypass?
Yes. Gearnews reported that the LTD Digi-Delay is true bypass, so with the pedal off your dry signal passes through without buffering or coloration. It also runs from a 9V DC power supply or a battery.
Can the Mr Black LTD Digi-Delay run on a battery?
Yes. Alongside a 9V DC power supply, the pedal operates from a battery, which is handy for players who do not use a pedalboard power supply. No current draw figure was published.
How long is the delay time on the LTD Digi-Delay?
Up to 900ms, according to Mr Black's product page and both Gearnews and MusicRadar coverage. Mr Black describes the repeats as crisp and articulate, with a hint of subtle modulation that only shows itself when desired.
Is the Mr Black LTD Digi-Delay still available?
No. It was a limited run, and Mr Black marked it sold out on 28 July 2016, about three weeks after launch. Finding one now means the second-hand market.
Does the LTD Digi-Delay self-oscillate?
Yes. Mr Black's product page lists self-oscillation on demand, meaning the repeats can be pushed into runaway feedback when you want it, in the style of vintage echo units.
How much did the Mr Black LTD Digi-Delay cost?
The list price was $179.95 USD, plus shipping and taxes, as reported by Gearnews at launch in July 2016. MusicRadar's launch coverage gave the price as $179.
