Key Points
Klowra's Rilum Stereo Multi-Head Tape style Delay, Chorus, Flanger and Vibrato is a stereo, tap‑tempo delay with 3 playback heads. Secondary heads are set relative to the main via Spawn, Heads Volume, Groove and Sum‑Invert. Lag Time covers short (flanger/chorus/vibrato) to longer delay; Modulation RATE and Mod Depth can be extreme; Lo‑Fi applies a filter.
I/O: 1/4" TS L/R in & out, 1/4" TRS expression/control, USB‑C, 9V DC [-] 250mA. Alt LEDs: WHITE/BLUE (Tap/Twisted), ORANGE/VIOLET (Ramp). Power‑up: True/Buffered Bypass (Trails), Tap/Twisted Tempo, Ramp Lock, LED Brightness.
Available from the Klowra Webstore, select dealers and Amazon.com. As of 2026-07-13, the price was £95.
This is such a smart pedal - it took me a while to figure out all the controls and their impact - but it’s mostly second nature now. I had to do a lot of experimentation for it all to slot into place for me. Klowra’s Jinbo was very helpful in getting me to understand the interplay between the main variable playback head - and the further fixed relative playback heads - which you can dial in and out of action or accentuate - by using the [Spawn], Heads Volume, [Groove] and [Sum-Invert] parameters in particular.
Those all impact on the secondary heads - which you can dial out entirely if you wish to simplify things or use them in combination courtesy of the Groove parameter - which controls 3 different heads at set timing intervals.
It functions very uniquely compared to my dozen or so other Multihead Tape-style effects - mostly punctuated by Strymon’s Volante - and a number of Boss delays - all the Space Echo ones in particular.
The Rilum Multihead tape style delay / delay line is an entirely new and distinct tape style effect - it has 3 playback heads which puts it kind of adjacent to an Echoplex - while this design is entirely original, and as conceived by those super smart Klowra engineers.
As a Delay Line Manipulator it deliver short delays - for Flanger, Chorus and Vibrato sounds, and longer timings for classic delay sounds. The Modulation - RATE and Depth can get incredibly wild - and I found myself dialling that down constantly - and a number of the secondary controls in particular accent or soften those other playback heads in a variety of ways.
This is an absolutely killer Delay Line Modulator - which delivers Classic, Weird, Wobbly, Otherworldly, Vintage and Modern sounds. It’s not always the easiest to dial in - but it really does deliver the goods with a little due diligence.
A really smart and unique pedal - which is of course fully stereo, and has a couple of different Tap Tempo Effects, alongside Ramping. This is another killer pedal from Klowra - it might even be my favourite to date!

The Controls - LAG TIME [Spawn : Randomised Heads Volume : more accentuated CW], FEEDBACK [RampATK], MIX [RampRLS], (Modulation) RATE, [Mod Depth], relative HEADS VOLUME [Groove : .8th > .8th + 8th > 8th > 8th + Quarter Triplet > Quarter Triplet], LO-FI [Sum-Invert : Relative Phase of Other Heads : In Phase CCW and Out of Phase CW].
Ports - 1/4" TS Left In, 1/4" TS Right In, 1/4" TRS Expression and Control, USB-C, 9V DC [-] 250mA, 1/4" TS Left Out, 1/4" TS Right Out.
As mentioned - you have one main fully variable Tape Head, where you can adjust the secondary heads in relation to that - using the Spawn - which randomises the Volume of the secondary Heads - I tend to have that dialled out - so that the Volumes are more regular (anti-clockwise), Heads Volume lowers the Volume of the secondary Heads, and 'GROOVE' determines which heads are active - in addition to the main variable head - you sweep through .8th, 8th, and Quarter Triplets individually and in combination - as detailed for the main controls segment - [Groove] : .8th > .8th + 8th > 8th > 8th + Quarter Triplet > Quarter Triplet].
Finally Lo-Fi applies a filter - which softens the output and makes it more aged and vintage sounding. The [Sum-Invert] setting sets the relative Phase of the other / secondary Heads versus the main head - whether those are In or Out of Phase with the Main Head.
So each of those controls adjusts the relative output of the secondary Heads - you can pretty much dial those out in various ways - which is not possible with the Main Playback Head.
The Lag Time adjusts the Delay Line Range - where the first hemisphere is shorter delays for Flanger, Chorus and Vibrato, while over the mid-way point you move into longer Delay style timings.
I found myself adjusting the Mod Rate and Depth a lot - for every one of me Presets - that was a core part - dialling the depth Down in particular.
You can see from the Demos that a huge variety of special effects is possible by manipulating all those controls - the Rilum really leans into the wobbly and otherworldly - while it's capable of amazing Classic Sounds too - per my suggested Presets.
As with every Klowra Pedal you have a number of Alt Button effects
And you of course have a number of Power-Up Modes / Options too as always :

Like a lot of the Klowra devices - this one has much to do with the balancing of the output of those various controls. It's not always the easiest pedal to dial in - but patience and due diligence is well rewarded - and it didn't take me too long together the hang of the Rilum.
Unlike some of the other Klowra pedals - where I don't use the Secondary Options that much - for this one I was all over those controls all the time - both layers.
Part of me wishes these could be dual-concentric controls - as it's so easy to forget where you set the secondary parameters - you soon forget exactly where you set it - and I spent a lot of time figuring out where the secondary controls were pointing. We really need some visual cues to make that recall easier - where the Bixonic line of pedals uses lots of tiny LEDs around each knob - to easily show you where those parameters are set.
I spent so much time with the Rilum figuring out the relative positions of the secondary parameters - and then you move the knobs to adjust those - and you forget exactly where the primary is set. I have had that issue with a lot of pedals which have secondary and even tertiary options on the same knobs / controls. That can all get very confusing and frustrating at times.
The relative nature of all those playback heads means that there is a learning curve here - this one works very uniquely from every other Tape-style delay I was previously familiar with - but I actually really like how it works once I became better acquainted with all the controls and exactly how those impact.
The pedal can get very wayward and wobbly at times in a cool way - but you can temper it amazingly for a series of gorgeous classic sounds too.
I love how potent the Rilum is - but wish that the control topology was a little more logical and recallable. I kind of have a pet peave with secondary controls effects - as you are forever adjust those controls back into place - and you're never entirely sure you've hit on exactly the same spot again. There has to be some way to make that side of the pedal more accessible - where there is no doubting how smart, potent and capable this pedal is. It really has an extraordinary array of useful outputs.
I have a number of delay-line manipulators - like say the Fjord Fuzz Loke - which is rather more straightforward in use. I also tend to prefer pedals where you flip to secondary mode and adjust all those secondary controls in a broad sweep - while for the Rilum you spend a lot of time holding down the LED alt button, and individually adjusting all those secondary functions which is a little clunky.
The Rilum definitely has its own logic - and once you've cracked that it's more starightforward - while I kept on being frustrated by trying to figure out what other settings I had assigned to each particular knob. They often looked out of position unless you remember to dial them back again after every secondary tweak. In any case I really wished for fully independent dual-concentric knobs - so that the relative parameter settings - primary and secondary - could always be clearly referenced.
There is so much going on here at times - that it can get a little challenging - while I was delighted with the range of patterns, tones and textures I was able to create with this pedal - my Vintage Tape Style setting - is just gorgeous - and beautifully softened by the Lo-Fi control.
My mood determines what settings I go for - and for this pedal I was largely in a classic timeless mindset - and my recommended presets reflect that!

As you can see from the nature of my presets I was definitely in a classic and vintage state of mind. I spent a lot of time getting the Modulation part to sound just right - where most of the time I lost touch with the respective secondary settings - I kept forgetting where the secondary parameters were set - and had to come back to those several times and make several tweaks. Generally for this kind of pedal I'm mostly dialling things by ear - and I don't always look down to see where the knob has landed - so recalling secondary parameters is somewhat challenging for me.
Part of the process of dialling those controls in - was a little frustrating, but I was always very happy with the event results. Basically the Flanger had the most modulation dialled in, the Chorus was somewhat tempered, and the Classic Delay more refined still on the Modulation side.
Overall I'm really delighted by this pedal - surely my favourite Klowra to date - I just wish the dial-in could be a little easier and more regular!

The Klowwa Rilum is exceptionally well priced at $129 / £95 and equivalent from the Klowra Webstore, also at select International Dealers, and available on Amazon.com.
