The Non-Human Audio Slow Loris is a dynamically driven lo-fi modulated slapback pedal: a very short delay whose delay time is tied to your picking envelope. On That Pedal Show, Chris Benson described it as "like a modulated slapback so it's a delay very short delay but that delay time is tied to the envelope"1. Non-Human Audio says with its unique control set it "will go anywhere from a subtle atmospheric vibrato/chorus to a delayed sea-sick warped vinyl lo-fi sound"2. It sits in the wider family of delay pedals, but its character comes from that dynamic, envelope-driven wobble rather than from long delay times.
How it plays and what the controls do
The pedal has two knobs3, and the control knob is the heart of it. Non-Human Audio describes its behavior this way:
"With the control knob up it becomes more sensitive and instable, play lightly and you'll experience a more subtle modulated slapback, but dig in and hit the pedal harder and you'll trigger a deeper vibrato"
In practice that means the pedal responds to how hard you play: light picking stays in subtle modulated slapback territory, while harder attack pushes it into deeper vibrato and more instability. Players who like touch-responsive effects will find the picking envelope, not just the knob settings, shaping the sound21.
Noise: what is normal and how to tame it
The Slow Loris is deliberately lo-fi, and that comes with audible texture. Non-Human Audio is direct about it2:
"Because of the nature of this circuit there is an inherent small amount of noise in the effect. There is some static and crackle, and that's normal"
- The static and crackle are described by the maker as an inherent part of the circuit, not a fault2.
- You will probably notice it more with hotter or more bassy pickups; humbuckers tend to bring it out more frequently2.
- The maker's workaround: "Usually if you dial back your guitar volume a tiny bit it'll clean it up"2.
If your Slow Loris crackles, that is the circuit, not a defect, according to the maker. Rolling back the guitar volume slightly is the recommended fix2.
Where it came from and the Florist connection
Non-Human Audio introduced the two-knob Slow Loris Short Delay Line Dynamic Modulator about a year before July 2024, and Guitar Pedal X's Stefan Karlsson reported that it was "incredibly enthusiastically received" on release. He described it as slightly reminiscent of delay line modulators like the Fjord Fuzz Loke and Spaceman Effects Meridian, but hugely simplified, with a slightly dissonant nature to the output overall3.
The Slow Loris arrived quietly and found its audience by word of pedalboard. Non-Human Audio introduced the two-knob Slow Loris Short Delay Line Dynamic Modulator about a year before July 20243. The pedal's behavior is deliberately touch-sensitive: "With the control knob up it becomes more sensitive and instable, play lightly and you'll experience a more subtle modulated slapback, but dig in and hit the pedal harder and you'll trigger a deeper vibrato," the maker explains2.

Questions
How much does the Non-Human Audio Slow Loris cost?
The Slow Loris is listed at $175.00 USD on Non-Human Audio's product page, as of 26 October 2026. It is a compact two-knob pedal, and the maker also offers a free PDF manual download for it from the same page.
Is the static and crackle on the Slow Loris normal?
Yes. Non-Human Audio says that because of the nature of the circuit there is an inherent small amount of noise in the effect, and that some static and crackle is normal. The maker also notes you will probably notice it more with hotter or more bassy pickups, and humbuckers tend to bring it out more frequently.
Do humbuckers make the Slow Loris noisier?
The maker says the noise is more likely to show up with hotter or more bassy pickups, and that humbuckers tend to bring it out more frequently. It is described as an inherent part of the circuit rather than a fault.
How do I reduce the noise on the Slow Loris?
Non-Human Audio suggests dialing back your guitar volume a tiny bit, which usually cleans the noise up. The maker also mentions using the pedal in conjunction with a lot of another element, though the full recommendation is cut off in the published text.
Where can I find the Slow Loris manual?
Non-Human Audio links a Slow Loris manual download as a PDF from its product page, hosted on Google Drive. The link was live on the maker's page as of 26 October 2026.
