The Experimental Noize Aphazing is a digital phaser pedal from Los Angeles-based maker Experimental Noize. It covers the classic phase sounds guitarists have used for decades, but it is built for players who want to go beyond them: a Stages control shifts between 2, 4, 8, and 12 phasing stages, and a Mode knob selects four different ways the effect is generated1. Premier Guitar reviewed it in 2021 and called it "a great-sounding and bargain-priced digital pedal," priced at $169 when purchased directly from Experimental Noize2.
The controls
The Aphazing's control set is unusually wide-ranging, and Premier Guitar's reviewer called it one of the pedal's star features2. The standard Rate, Depth, and Resonance knobs are present, alongside controls that are less common on a phaser1.
| Control | What it does |
|---|---|
| Rate | Sets the speed of the phase sweep21 |
| Depth | Sets how deep the effect goes21 |
| Resonance / Feedback | Sets the feedback or resonance of the sweep21 |
| Stages | Shifts between 2, 4, 8, and 12 phasing stages1 |
| Mode | Tails the type of phase the pedal produces1 |
| Limit controls | Adjust the heads and tails of the effect, letting you choose which part of the waveform to emphasize1 |
The Stages control is where much of the pedal's range lives. In the reviewer's experience, 2-stage phasing provides a straightforward, tape-like sound, while the 12-stage setting is thick and complex, and the 4- and 8-stage options split the difference2.
The four modes each generate the effect differently:
- Mode A: What most players think of as a regular phase sound, combining the dry signal with a slightly offset, pitch-modulated wet signal. It is capable of traditional phasing tones in the Phase 90/Small Stone vein2.
- Mode B: Blends the signals subtractively, producing hollow-sounding tones with greater phase cancellation2.
- Mode C: Introduces asymmetric modulation with a "fishhook" twist reminiscent of a Uni-Vibe2.
- Mode D: A thinner-sounding subtractive version of Mode C2.
Build and layout
The Aphazing lives in a large-format folded-steel enclosure, roughly 7" x 5" x 2", and Delicious Audio described the pedal as about 8" tall21. Inside are two stacked circuit boards populated with modern micro-components and linked by a ribbon connector, with board-mounted jacks and pots, both boards securely affixed to the enclosure2. It runs a 32-bit processor1.
The pedal is powered by a standard 9V supply, which is not included, though a sealed battery box is fitted2.
What reviewers said
Premier Guitar's 2021 review was largely positive about the sound. The reviewer found the core sounds "terrific: rich, detailed, and convincingly analog-sounding" for a digital pedal, and summed up the pros as fine vintage-style phasing, countless cool and musical variations, and a great price2.
"Aphazing sounds awesome on everything from simple '60s-style phasing to weird, wild wobbles."
The criticism was aimed at the control layout rather than the tone. The reviewer found a confusing, near-random layout: controls not grouped, not visually differentiated, labels in small type that are hard to read, and an enclosure graphic that adds to the confusion. Still, the reviewer concluded it is not a deal-breaker, and that you will learn your way around after spending some time with the pedal2.
Delicious Audio, featuring the pedal ahead of the 2016 Brooklyn Stompbox Exhibit, described it as one of the most versatile phase shifters out there, able to achieve the classic phase sounds loved by guitarists for decades but aimed at players who are not afraid to break new sonic ground1.

Questions
Is the Experimental Noize Aphazing stereo?
No. Both the input and the output are mono only. Premier Guitar's reviewer noted, though, that despite the mono signal path the tones still feel wide and immersive.
Is the Aphazing analog or digital?
It is a digital pedal. Premier Guitar described it as a great-sounding, bargain-priced digital pedal, and it runs a 32-bit processor. The reviewer found its core sounds convincingly analog-sounding.
Does the Aphazing take a battery?
Yes. It runs on a standard 9V power supply, which is not included, and it also has a sealed battery box inside the enclosure.
What do the Aphazing's four modes sound like?
Mode A is a regular phase sound in the Phase 90/Small Stone vein. Mode B blends signals subtractively for hollow tones with more phase cancellation. Mode C adds asymmetric modulation with a Uni-Vibe-like fishhook twist, and Mode D is a thinner subtractive version of Mode C.
How big is the Aphazing?
It lives in a large-format folded-steel enclosure roughly 7 by 5 by 2 inches, and Delicious Audio described the pedal as about 8 inches tall. It is noticeably larger than a standard compact stompbox.
