Old Blood Noise Endeavors Old Blood Noise Dweller Phase Repeater

The Old Blood Noise Endeavors Dweller Phase Repeater is a phaser pedal with a twist: a delay sits inside each phase stage, and a single knob moves the effect between phaser, delay, and reverb territory. Old Blood Noise Endeavors coined the term "phase repeater" for it because no existing effect name fit. In the maker's words¹²:

Under the hood it is still a phaser in the classic sense. As the maker describes the circuit, "It is a collection of allpass filters modulating to create an irreplaceable sound"¹. Delicious Audio framed it as "a phaser with sample stretching circuit inside the phaser, which creates some unexpected variations on that classic effect," covering ground "from familiar phase and vibe sounds to resonant random step filtering, warm delays, and previously unheard in-betweens"². The pedal was released in July 2018³ and the maker's page lists it as sold out as of October 2026¹.

What a phase repeater is

A conventional phaser splits the signal through a chain of allpass filters, each shifting phase at a different frequency, then recombines them so notches sweep up and down as the filters are modulated. The Dweller keeps that architecture but puts a short delay inside each stage. The Stretch knob sets that delay time, and because the delay length determines how far apart the phase notches land, one control reshapes the whole effect¹².

At one end of Stretch the pedal sits in familiar phase and vibe territory. As Stretch increases, the repeats inside each stage stretch out, and the output leans toward warm delays and reverb-like washes². Guitar.com highlighted this when the pedal launched, noting that the Stretch control "can be controlled on the fly with an expression pedal"³.

Controls and modes

The Dweller carries five knobs and two toggle switches, giving six modes in total².

The two toggles are where the six modes come from: two phaser voices (four-stage and eight-stage) crossed with three LFO wave shapes (sine, triangle, and random step)². Gearnews confirmed the four- and eight-stage options at the pedal's launch, noting that "Sin, triangle, and random step shapes are available"⁴. Four stages give a subtler, more classic phase sweep; eight stages double the notches for a deeper, more dramatic sweep. The random step shape jumps between values rather than sweeping smoothly, which is what produces the resonant stepped filtering Delicious Audio described².

There is also an internal trimpot for output level, useful for matching volume with the bypassed signal or pushing the pedal a little hotter².

Power and connections

The Dweller runs on standard 9V DC center negative power, the same supply as most pedals on a typical board². The maker's page lists an expression jack for external control of Stretch¹, so an expression pedal can sweep the delay time inside the stages in real time, which Guitar.com called out as a live performance option³. No battery operation is mentioned in the maker's or press descriptions.

On switching, the sources use slightly different language. The maker describes a "soft-touch bypass footswitch for true bypass and minimal switch noise"¹, while Delicious Audio describes "relay bypass switching and standard 9VDC center negative power"². Relay-based soft-touch switching is a common way to achieve true bypass electronically, so the descriptions point at the same behavior, but the terms differ.

Where it came from

Old Blood Noise Endeavors released the Dweller Phase Repeater as a pre-sale offering at $199, with a ship date of August 6th². The pedal uses relay bypass switching and standard 9VDC center negative power².

The Dweller has also found users beyond guitar. In a JHS Pedals piece on guitar pedals for synths, Nick included the Dweller Phase Repeater among the pedals worth running with synthesizers⁵, which fits a pedal whose random step wave and stretchable delays respond well to program material other than a guitar signal.
