The Kodex Audio GFX-91W is a mono digital delay pedal with up to 10 seconds of delay time, five on-board presets, tap tempo and a built-in modulation control. It is aimed at players who want long, adjustable delay in a compact pedal, and both reviews of it appeared in early 2024.12
Controls and how it works
The Time knob sets the delay length, and it works across three switchable ranges so that a single knob stays usable from short slapback to very long repeats: 10 to 400 ms, 100 to 1000 ms, and 500 to 9999 ms.1
| Control | What it does |
|---|---|
| Time | Sets delay time, up to 10 seconds, across three switchable ranges12 |
| Range | Switches the Time knob between 10-400ms, 100-1000ms and 500-9999ms1 |
| Age slider | Adds modulation to the repeats1 |
| Tap Tempo footswitch | Sets delay time by tapping12 |
| Presets | 5 on-board presets, plus Manual mode12 |
For sync'd playing, the pedal offers six note subdivisions: quarter note, half note, eighth note, dotted eighth note, quarter note triplet and eighth note triplet.1
The 1.3" OLED display shows the delay time in BPM or milliseconds along with the other important parameters, like subdivisions, tails status and the active preset.2
The GFX-91W is a mono delay pedal. Guitar Pedal X's Stefan Karlsson, who profiled the pedal, noted: "It's a Mono delay pedal - so not really perfect for my stereo rig."2
Analog dry path
Pedal of the Day's review highlights one practical point for tone-conscious players: "The dry signal path is all analog, meaning your original tone will be left in tact, without coloration, when the effect" is bypassed.1 In other words, the digital processing handles the repeats while the dry signal stays analog.
What reviewers said
One published review describes the GFX-91w as a potent digital delay with smart parameters and controls and a cool form factor2.
- Pedal of the Day called it "a delay-lover's delight" and added: "not only is it a blast to experiment with, but it sounds incredible as well."1
- Guitar Pedal X's Stefan Karlsson concluded: "this is a pretty neat and actually quite potent digital delay with really smart parameters and controls - and that reall[y intriguing and easy to deploy form factor]."2

Guitar Pedal X reports that the GFX-91W is available from the Kodex Audio Webstore and Effekt Boutique.2

Up to ten seconds. The Time knob works across three switchable ranges: 10 to 400 ms, 100 to 1000 ms, and 500 to 9999 ms, so the pedal covers everything from short slapback to very long, ambient repeats.

Five on-board presets, plus a Manual mode. The display shows which preset is active along with the other parameters.

Quarter note, half note, eighth note, dotted eighth note, quarter note triplet and eighth note triplet. The display shows the selected subdivision along with BPM/MS, tails status and the active preset.
