The JPTR FX Super Weirdo is a fuzz pedal built around a pulse width modulator, a circuit that chops the guitar signal into pulses so the effect moves and shifts instead of sitting still. JPTR FX describes it as a Pulse Width Modulator Fuzz Pedal with a time-based modulation effect that adds movement and texture to your sound, from subtle noise to warbles and sweeps1. The maker pitches it at noise rock and avant-garde guitarists looking for innovative ways to be creative1.
The pedal is currently offered as a 10th anniversary edition: JPTR FX marks 10 years of the company with a run of 20 pedals only, finished in Analog Magenta1.
JPTR FX produces every model in batches and asks buyers to allow time for order fulfillment; orders go directly from the manufacturer1. The price is listed in pounds sterling on the maker's site.
Controls and the Glitch footswitch
Pedal of the Day's review walks through the panel. The main signal is set with basic Volume and Tone controls, the Tone setting the main signal tone2. The Time Amount knob adjusts the spacing between each of the mod pulses, layering your sound for off-the-wall repeats and exploration, and a Feedback knob adds modulation into the base signal, in essence doubling the effect produced, for otherworldly tones2.
| Control | What it does |
|---|---|
| Volume | Main signal level2 |
| Tone | Sets the main signal tone2 |
| Time Amount | Adjusts the spacing between each mod pulse, layering the sound for off-the-wall repeats2 |
| Feedback | Adds modulation into the base signal, in essence doubling the effect produced2 |
| Glitch (footswitch) | Momentary switch for bursts of glitchy oscillation2 |
The Glitch footswitch is the pedal's signature move. Because it is momentary, it only disrupts the signal while held down: Pedal of the Day calls it a momentary switch that lets you disrupt your signal with bursts of trippy oscillation2, and Delicious Audio's guide to unusual fuzzes says the momentary glitch footswitch allows for bursts of intense glitchy repeats3. An expression pedal input sits alongside it, giving foot control over the modulation while playing1.
What reviewers said
Pedal of the Day reviewed the Super Weirdo in January 2019 and framed it as a deliberate oddity among fuzzes2:
"this one is nothing shy of remarkable in its determination to be different, which we absolutely welcome"
The same review describes the pedal as utilizing a Pulse Width Modulator at its core, saying the Super Weirdo pulses and grooves like there's no tomorrow, and pictures it as a silver and black box that unleashes fury and rage2. Delicious Audio included it in a roundup of crazy, weird and unusual fuzz pedals, grouping it with designs built for glitch and chaos rather than conventional drive3.
Where it sits in the JPTR FX range
JPTR FX is a German pedal maker, and the Super Weirdo is its experimental corner of the fuzz lineup. Players who want a more conventional take on the maker's fuzzes can look at the JPTR FX Warlow, the JPTR FX Silvermachine or the compact JPTR FX WARLOW mini, which follow more traditional fuzz circuits. The Super Weirdo is the one built around pulse width modulation and momentary glitch control123.

Questions
What does the Glitch footswitch do on the JPTR FX Super Weirdo?
The Glitch footswitch is a momentary switch, so it only acts while you hold it down. Pedal of the Day describes it as letting you disrupt your signal with bursts of trippy oscillation, and Delicious Audio's write-up says the momentary glitch footswitch allows for bursts of intense glitchy repeats. It is a tool for short, deliberate stabs of chaos rather than a sound you leave on.
Does the Super Weirdo have an expression pedal input?
Yes. JPTR FX's product page lists an expression pedal input alongside the Glitch footswitch, so you can control the pedal's modulation with your foot while both hands stay on the guitar. A standard expression pedal is connected separately from the guitar signal chain.
How many Super Weirdo pedals were made?
The 10th anniversary edition was limited to 20 pedals only, finished in Analog Magenta. JPTR FX marked the run as celebrating 10 years of the company. The maker produces every model in batches, so availability depends on when a batch is built.
What does the Feedback knob do on the Super Weirdo?
According to Pedal of the Day, the Feedback knob adds modulation into the base signal, in essence doubling the effect produced, for otherworldly tones. It works together with the Time Amount knob, which adjusts the spacing between each of the mod pulses and layers your sound for off-the-wall repeats.
What is a pulse width modulator fuzz?
A pulse width modulator fuzz is a fuzz design built around a pulse width modulator, a circuit that chops the signal into pulses rather than passing it continuously. Pedal of the Day describes the Super Weirdo as utilizing a Pulse Width Modulator at its core, saying the pedal pulses and grooves like there's no tomorrow. The result is a fuzz with built-in movement and texture rather than a static distortion.
How much does the JPTR FX Super Weirdo cost?
JPTR FX lists the Super Weirdo 10YRS EDT at £129.00, with taxes included, as of the maker's product page dated 26 October 2026. The price is given in pounds sterling on the maker's site, and orders are fulfilled directly by the manufacturer.
