The GUP Tech Moby Depth Douche Edition is a spring reverb pedal with a set of adjustments GUP Tech says make it unique among reverb pedals, including a Regen control that feeds the effected signal back into the reverb the way a delay's feedback knob recycles echoes1. GUP Tech describes the sound in its own words: "Push it in the deep to feel like you're wandering in a whale."1
The Douche Edition is a version of the standard GUP Tech Moby Depth, sharing the same control set, enclosure and circuit. As of late October 2026, GUP Tech lists it as re-stocking soon1. The pedal is made by GUP Tech in Saguenay, Québec, Canada, and the maker states that all of its pedals are built in-house there1.
A spring reverb pedal with a regen control
GUP Tech calls the Moby Depth "basically a spring reverb, but with many adjustments that make it unique among other reverb guitar pedals"1. Rather than a mechanical spring tank, the circuit uses Accutronics (Belton) digital reverb technology, the same approach GUP Tech uses across the Moby Depth line1. The standard Moby Depth page lists the same foundation, along with decay adjustment and tone shaping2.
The pedal's distinguishing feature is Regen. Premier Guitar, reviewing the earlier Jonny Rock Gear version of the Moby Depth, described it as "the bonus regen feature (essentially like a delay's feedback function)"3. Pedal of the Day explained the mechanism in its review of the same pedal: "Regen to control the amount of effected signal sent back in the reverb (Feedback)"4. In practice, this means the reverb can be made to sustain and swell on itself instead of simply decaying, which is what separates the Moby Depth from a straightforward spring emulation.
The two reviews also describe how the controls interact. Pedal of the Day found that "The Regen and Depth controls work in tandem as well, with more Depth producing a more powerful, deeper Regen effect"4. So the depth of the reverb and the amount of regeneration feed each other: a deeper setting makes the Regen effect more pronounced.
The controls
The Douche Edition carries the same control set as the standard Moby Depth. GUP Tech's descriptions of each knob1:
| Control | What it does |
|---|---|
| REVERB | Overall volume of the reverb and insert |
| DECAY | Length of the reverb |
| TONE | Brightness control |
| MIX | Blends the wet effected signal with your dry sound |
| REGEN | Feeds effected signal back into the reverb, like delay feedback |
The insert loop is the other notable part of the control surface. Two jacks, SND and RTN, let you place another effect inside the reverb path: SND goes to the input of any effect pedal, and RTN receives that pedal's output1. That means you can run an overdrive, fuzz or filter into the wet signal only, so the inserted effect processes the reverb tail rather than your whole guitar signal. The REVERB knob governs the overall volume of both the reverb and this insert path1.
Premier Guitar's review of the Jonny Rock Gear Moby Depth confirms the same layout on that version, listing "reverb level, decay, tone, and wet/dry mix knobs" alongside the regen control3.
Circuit and limited edition
The Douche Edition is built on Accutronics (Belton) digital reverb technology, in a powder coated die cast aluminum enclosure1. Pedal of the Day described the Jonny Rock Gear original as using the same technology, "resulting in a lush, exploratory reverb effect"4, and Premier Guitar noted that the Jonny Rock Gear version "is driven by a Belton BTDR-3 chip"3.
The Moby Depth appears in several editions: the standard Moby Depth, the Gold Rush Edition, and this Douche Edition12. Both the standard pedal and the Douche Edition use a powder coated die cast aluminum enclosure12, and the Douche Edition's reverb circuit is built on Accutronics (Belton) digital reverb technology1.
Power comes from a standard 9V AC adapter with a DC output and negative center1, the same arrangement as most modern pedals, so it fits a typical center-negative pedalboard supply.
GUP Tech lists both the Douche Edition and the standard Moby Depth as re-stocking soon as of 26 October 2026, so neither is currently in stock direct from the maker12.
Questions
What does the Regen knob do on the Moby Depth Douche Edition?
Regen controls the amount of effected signal fed back into the reverb, working much like a delay pedal's feedback control. Pedal of the Day noted that Regen and Depth work in tandem, with more Depth producing a more powerful, deeper Regen effect. Turning it up makes the reverb sustain and build on itself rather than simply fading out.
What is the SND control on the Moby Depth?
SND is the send side of the pedal's insert loop. It goes to the input of any effect pedal, while the matching RTN jack receives that pedal's output. This lets you run another effect, such as an overdrive or filter, inside the reverb path so it processes the wet signal.
Where is the GUP Tech Moby Depth made?
GUP Tech builds all of its pedals itself in Saguenay, Québec, Canada, including the Moby Depth Douche Edition. The pedal comes in a powder coated die cast aluminum enclosure.
What power supply does the Moby Depth Douche Edition use?
It runs on a standard 9V AC adapter with a DC output and negative center, the same arrangement as most modern guitar pedals. That means it works with typical 9V center-negative pedalboard power supplies.
Is the Moby Depth Douche Edition still available?
As of late October 2026, GUP Tech's product page lists the Douche Edition as re-stocking soon, so it is not currently in stock at the maker. The standard GUP Tech Moby Depth is listed the same way. Interested players would need to watch for the restock.
