Amidst the hype, Walrus Audio quickly realised that limiting the production run to 600 units might have been a bit naive. Good news: The Lüm Texture Engine is back! And now permanently available!
Lüm Texture Engine now available: Matte Black and Guava Gloss
Two new colour options for the pedal are now available at Thomann: Matte Black and Guava Gloss. Each model costs €299.00, the same as the original version.
Walrus Audio Lüm Texture Engine
[September 16, 2025] Walrus Audio loves creating ambient effect pedals, and this latest release takes some of their previous designs and adds some elements to the Lüm Texture Engine.
They also took inspiration from the algorithms of Fable, Lore, and Slö, combining elements of all three to create a new ambient sound.
Three Modes
There are three effect modes available, and each has something different to offer.
- Grain Cloud: Granular cloud with two granular taps fed into a feedback delay line.
- Grain Verb: A granular reverb, this one “reads” two granular taps from the reverb effect. It’s great when combined with distortion.
- Forward-Reverse Verb: A forward reverb algorithm that transitions into a backward reverb algorithm.
Use the three-way switch in the middle to select a mode, and then use the five controls to adjust the detailed settings.
Automation
The Lüm offers a wide range of sounds just with its three modes, but it also has a trick that’s rare for a pedal: you can automate each of the five controls between two different settings using the Moment footswitch.
Controls
Decay controls the reverb time, Filter dampens peaks in the signal, and Mix adjusts the blend of dry and wet signals.
The X control changes depending on which of the three modes you’re in. In Grain Cloud and Grain Verb, it adjusts the size and frequency of the grains. In Forward-Reverse Verb, it lets you set the reverb time for the reverse reverb. Finally, Stretch continuously adjusts the sample rate from half to double.
You can set a starting value for a parameter, such as the Mix control, and then a final value. When you press the Moment footswitch, the Lüm will automatically shift the parameter from the start to the end value. You can also control the speed of this transition with options for 10 ms, 1000 ms, or 5000 ms.
For a smoother sound, the optional Trails function lets the reverb tail fade out naturally even after you bypass the effect.
Price & Availability
You can get the Walrus Audio Lüm Texture Engine for $293 /£263/€299 at Thomann. And you’d better act fast, because the pedal is limited to 600 units worldwide.
If you enjoyed the Slö Reverb, Lore Reverse Reverb, and Fable Granular Generator, then this pedal is probably for you.
