The Epigaze Audio Singularity MKII is a fuzz pedal from Epigaze, sold in two versions: the Singularity Vintage MKII and the Custom Shop Expanded Vintage MKII Fuzz. The listing describes its range as running "from smooth, gated, and borderline octave fuzz tones," which puts it among the more versatile fuzzes: it can sit anywhere from a conventional smooth fuzz to a gated, sputtering, octave-tinged sound1.
The Custom Shop Expanded version is described by the maker as "the same great sound of our Singularity fuzz with more options," meaning the core circuit and sound carry over from the standard pedal while the Expanded version adds extra controls1.
Controls
The Singularity MKII's control set is built around two named knobs, with the Expanded version adding three internal-style bias controls12.
| Control | What it does | Version |
|---|---|---|
| Horizon | Controls the attack of the fuzz | Both12 |
| Gravity | Controls the level or volume | Expanded1 |
| Q1 to Q3 | Adjust the bias voltage | Expanded1 |
The Horizon knob is the unusual one. Instead of a conventional tone or fuzz-amount control, it shapes the attack of the fuzz, so it changes how the effect hits when you pick rather than how much gain or brightness it has12. Gravity is the output level control, setting how loud the fuzz is relative to your clean signal1.
The Q1 to Q3 controls, found only on the Custom Shop Expanded version, adjust the bias voltage of the circuit's transistors. Biasing a fuzz transistor differently changes its behavior, and on this pedal that is what opens up the range from smooth fuzz to gated and octave-adjacent tones1.
The Custom Shop Expanded version
The Expanded Vintage MKII is the fuller-featured of the two versions. It keeps the Horizon and Gravity knobs and adds the Q1 to Q3 bias controls, giving you direct access to the transistor biasing that shapes the fuzz character1. The Vintage MKII carries the same core sound and the Horizon control, with Switchcraft jacks on both pedals2.
The name "Singularity" is shared with an unrelated pedal from Collision Devices, whose Singularity is a different design with a single control: "the only knob controls the master fuzz volume"3. The two pedals should not be confused despite the shared name.

Questions
What does the Horizon knob do on the Singularity?
The Horizon control sets the attack of the fuzz. Rather than a tone or gain control, it changes how quickly the fuzz character hits when you pick, which lets you move between smoother and more aggressive attacks across the pedal's range.
What do the Q1-Q3 bias controls change?
On the Custom Shop Expanded version, the Q1 to Q3 controls adjust the bias voltage of the transistors in the fuzz circuit. Biasing the transistors differently changes the fuzz's character, including how smooth or gated the tones come out.
Does the Singularity MKII use Switchcraft jacks?
Yes. Both the Singularity Vintage MKII and the Custom Shop Expanded Vintage MKII are listed with Switchcraft jacks, a widely used US-made jack brand known for durable metal construction on pedal inputs and outputs.
What is the difference between the Singularity Vintage MKII and the Expanded version?
The Custom Shop Expanded Vintage MKII is described as the same sound as the Singularity fuzz with more options. The Expanded version adds the Q1 to Q3 bias controls on top of the Horizon and Gravity knobs found on the Vintage MKII.
