The DYBBUK "Legba Vibe" is a handcrafted analog vibe pedal from Dr. No Effects, the third and final part of the maker's SORCIÈRE trilogy of effects based on the occult, sorcery and myths. It is a vintage style Uni-Vibe, built with the parts the maker considers essential to that circuit: a real filament light bulb and LDRs (Light Dependent Resistors). The effect it produces, the "Legba Vibe", was developed by Dr.No and named after Papa Legba1.
The DYBBUK is built by hand in a limited edition of 250 pieces, released in a series of 50 at a time, so availability depends on when a new series is released1.
A limited edition in the SORCIÈRE trilogy
The SORCIÈRE trilogy is a series of three effects based conceptually and tone-wise on the occult, sorcery and myths. The final part is the DYBBUK, described by the maker as "a vintage style UniVibe with light bulb"2. The DJINN and the NecroFuzzicon are exclusively available through the maker's own webshop3.
The DYBBUK was announced on 2022-06-22 as a handcrafted analog limited edition of 250 pieces, with the first series of 50 available for pre-sale41. The first series is signed and numbered 01 to 50/250, and the maker states that the second serie is available now, handmade in small series each time1.
The Uni-Vibe circuit and the light bulb
The pedal is based on the authentic Vibro-Chorus, later called the Uni-Vibe. Dr. No Effects describes that original this way14:
"The Vibra-Chorus (later called Uni-Vibe) was known for its throbbing, hypnotic pulse, and atmospheric tone."1
The maker adds that it is widely believed the effect was intended to mimic the "Doppler sound" of a Leslie speaker. Although the effect is often associated with chorus or phaser pedals, Dr. No Effects explains that it is in fact created by a staggered series of phasing filters, an optical circuitry that uses LDRs, and the lamp1. Only the authentic Vibro-Chorus effects have a real filament light bulb and LDRs, and the DYBBUK uses those original parts1.
Controls
The DYBBUK keeps its control layout as simple as the original design: two knobs, both acting on the lamp that drives the optical circuit14.
| Control | What it does |
|---|---|
| GILGUL | Controls the strength of the DYBBUK "Legba Vibe" light, and thus the intensity or presence of the effect1 |
| MITZVAH | Controls the speed of the lamp1 |
On the press release version of the pedal, the GILGUL knob sits on the left side and is made of a human Ulna hand bone4.
Power and size
The DYBBUK operates on 9V and requires a minimum safe working current draw amperage of 50/100mA for optimal operation. The power supply input is a standard 2.1mm connector with a negative tip and a positive sleeve. Because of that current requirement, it is worth noting for pedalboard planning that the pedal draws more than many compact analog effects. Its enclosure measures 20cm x 13cm x 10cm (LxWxH)1.
Dr. No Effects states that the DYBBUK is completely handcrafted, component after component and one by one, by Dr.No, and that the maker focuses on analog effects exclusively1.
Questions
What is a Vibro-Chorus or Uni-Vibe?
The Vibra-Chorus, later called the Uni-Vibe, is a vintage effect known for what Dr. No Effects describes as its throbbing, hypnotic pulse and atmospheric tone. It is widely believed to have been intended to mimic the Doppler sound of a Leslie speaker. Although often associated with chorus or phaser, the effect is created by a staggered series of phasing filters driving an optical circuit.
How many Dr. No Effects DYBBUK pedals were made?
The DYBBUK is a limited edition of 250 pieces, released in series of 50 at a time. The first series was signed and numbered 01 to 50/250 and offered for pre-sale, and the maker states that a second serie is available, handmade in small series each time.
Does the DYBBUK use a real light bulb?
Yes. Dr. No Effects states the DYBBUK uses the original parts essential to an authentic Vibro-Chorus, including a real filament light bulb and LDRs (Light Dependent Resistors). The MITZVAH knob controls the speed of the lamp, and the GILGUL knob controls the strength of its light.
What does the GILGUL knob do?
GILGUL controls the strength of the DYBBUK "Legba Vibe" light, and thus the intensity or presence of the effect. On the press release version of the pedal it sits on the left side, with a knob made of a human Ulna hand bone.
What size is the Dr. No Effects DYBBUK pedal?
The dimensions are 20cm x 13cm x 10cm (LxWxH), or 7.87 x 5.12 x 3.49 inches, so it is a larger enclosure than a standard compact pedal.
