Glowfly Pedals Glitchwave567 Chaos Engine Review & Demo

This is a glitchy, lo-fi pedal that is meant for pushing the boundaries of guitar signal, in a good way.

Our 2025 review season continues to get off the ground with this so called Chaos Engine, which follows up on the Dalliter Fuzz from a few weeks ago. This pedal is the Glitchwave567 from Glowfly Pedals and it is quite the opposite of the aformentioned vintage inspired fuzz.

The Glitchwave is a filter pedal that serves to warp and distort your guitar signal in a variety of synth-inspired ways. It features a very powerful volume knob, which is really a wet volume, plus “fizz”, “freq”, and “dry” controls. “Freq” does what you would think, it really controls the frequency of the synthy, glitchy signal. Meanwhile, “dry” works well with the “volume” knob to blend in different amounts of the original guitar and pedal signals. And lastly, the fizz is another sort of filter control that provides a wide sweep of tone and EQ flavors.

Demo Time

In this demo you’re hearing my Fender Mexican HSS Stratocaster running into the Dalliter which is then hitting a Donner White Tape stereo echo, and my a relatively clean Fender Deluxe Reverb-flavored amp (UAFX Dream Amp Sim). All of that hits a Walrus DI box and then the audio interface.

My Thoughts

This is a brilliantly fun pedal, but it isn’t going to be for everyone. You really have to take time to sit down and sort out how the knobs interact together. That is usually NOT my cup of tea, however for this kind of a pedal I didn’t really mind sinking extra time into it. A big part of that is because once you turn this on, it’s really good fun. It smacks you in the face, and just doesn’t sound like a lot of other stuff on the market.

Obviously the Glitchwave567 is not the first pedal of this type to exist, but it is one of my first few experiences with one. So for me, it was an impressive learning experience. The Glitchwave567 can go off the rails incredibly quickly, but the knobs are very sensitive. So once you dial in a more usable sound, you can fine tune it within a reasonable amount. I found that the pedal produced a ton of volume, I rarely moved the volume knob past noon. That’s not really a drawback, but more of a warning. However, ever rig is different, so perhaps my guitar’s humbucker was just too much for it.

How am I going to use this? This will probably be a studio tool for me, mostly. It’s a great way to shake up a punk solo, as it’s a lot more distinct than just hitting a Whammy or octave pedal. It certainly cuts through, and I think the Glitchwave absolutely popped with some delay on top. I won’t say this is a pedal you’ll need every day, but when you’re in a rut or bored, this is will be a game changer. Also, if you wanted some synth sounds on your track or in your band, but don’t have a synth player, I could see this coming in super handy. And the best part is that the pedal is £80 (GBP), so even accounting for exchange, that’s a great price for a unique pedal like this.

TLDR: Very fun, but noisy and takes time to actually dial it in, super affordable.
