The Klowra Everlast is a stereo delay pedal with nine delay types, running from classic analog and tape emulations through digital delays to more experimental echo flavors like granular and reverse. Klowra positions it as part of the Bloom Infinity Series, and it carries that series' exclusive Ramp function alongside Tap Tempo, expression control and multiple stereo output modes including True Stereo and Ping-Pong1. Delicious Audio's Paolo De Gregorio described it as "a feature-rich stereo delay pedal offering 9 distinct delay types"2.
Guitar Pedal X's Stefan Karlsson called it "a 9-mode stereo delay workstation: Tape, Digital, Analog, Reverse, Swell, Granule, Crystal, Sweeper"3, and in his 2025 year-end round-up he grouped it among "just about the best budget pedals you can get for Delay, and Reverb" at a list price of $1294.
The nine delay modes
The Everlast's mode knob selects between nine algorithms43:
| Mode | What it is |
|---|---|
| Tape | Tape echo emulation |
| Digital | Clean digital delay |
| Analog | Vintage analog-style delay emulation |
| Reverse | Reversed repeats |
| Swell | Swelling, volume-fade echoes |
| Granule | Granular delay |
| Crystal | One of the more unusual "modern, inspiring" echo types1 |
| Sweeper | Another of the modern experimental modes3 |
| Modulated | Modulation-treated repeats |
Klowra groups these as "classic analog emulations, versatile digital delays, and modern, inspiring echoes"1, and Delicious Audio summed up the pedal as a "blend of musical delay algorithms and studio-grade signal preservation, catering to players seeking both traditional echoes and experimental sound design"2. Delay time runs from 20ms to 1200ms for precise rhythmic control3.
Controls, tap tempo and ramping
The pedal is powered by what RockBoard's PedalPedia calls a refined algorithmic engine, offering open parameter control and dynamic modulation1. The headline performance features:
- Tap Tempo: real-time control of the TIME parameter, syncing precisely to your BPM, with three rhythm modes35
- Rhythmic subdivisions: quarter note, dotted eighth note, or eighth-note triplet3
- Ramp function: exclusive to the Bloom Infinity Series, it sweeps parameters over time1
- Expression and footswitch: a TS/TRS momentary footswitch or TRS expression pedal connects via the CTRL / EXP port to unlock further creative possibilities13
Pedal of the Day's reviewer highlighted the same set: "Featuring NINE different modes, stereo connectivity, expression control, ramping and more"5.
Firmware updates arrive over the USB-C hardware interface on the top edge. Karlsson noted he had updated his unit twice, including the final launch firmware, calling it "a very simple procedure," though he found the process old-fashioned and clunky next to app-based updaters3.
Power, stereo routing and connections
The rear and top edges carry the connections: Left In, Right In, CTRL / EXP, Left Out, Right Out, and USB-C on the top edge3.
At 250mA, the Everlast draws more current than a typical analog pedal, so it needs a 9V DC power supply output rated for at least that, not a battery or a shared low-current daisy-chain tap3.
Stereo routing is one of the pedal's main selling points. Multiple stereo output modes include Ping-Pong, Dry/Wet Separation and True Stereo Outputs3, and Delicious Audio notes the routing options, including ping-pong and wide stereo, "provide flexibility in different setups"2. With two inputs and two outputs you can run a full stereo rig, use the second input for a second instrument, or split dry and wet signals to separate destinations.
| Specification | Value |
|---|---|
| Sample rate | 44.1 kHz3 |
| Sampling accuracy | 24-bit3 |
| Input impedance | 500k Ohm3 |
| Output impedance | 100 Ohm3 |
| Material | Sturdy aluminum alloy enclosure3 |
| Made in | China3 |
How it compares
Guitar Pedal X's reviewer considers the Everlast an evolved and improved iteration on the core algorithms of the similar ALABS delay pedal, and by December 2025 he rated it among the best budget delay pedals available4. Within Klowra's own line, the company has since released the Klowra Rilum Multi-Head Tape Delay + Modulation, a pedal built specifically around multi-head tape echo and modulation rather than the Everlast's nine-algorithm spread6.
What reviewers said
Published reviewers have been positive. Pedal of the Day's reviewer wrote that Klowra's pedals, including the Everlast Stereo Delay, "have blown me away"6. Guitar Pedal X's Stefan Karlsson, reviewing it at launch in July 2025, framed it as a workstation that "beautifully mixes up classic and more unusual flavours, which you can then ping-pong across the stereo spectrum"3, and by year end placed it among the best budget delay pedals of 20254.
"For sure just about the best budget pedals you can get for Delay, and Reverb!"
The pedal is available on Amazon.com and the Klowra webstore3.

Questions
Does the Klowra Everlast have tap tempo?
Yes. Tap Tempo gives real-time control of the TIME parameter and syncs precisely to your BPM, with three rhythm modes. Rhythmic subdivisions include quarter note, dotted eighth note and eighth-note triplet, so you can match the repeats to the groove rather than dialing in times by hand.
Is the Klowra Everlast true bypass?
It is switchable between the two. You can run True Bypass, where trails cut off when you disengage, or Buffered Bypass, where trails carry on after bypass. Either way the dry signal passes through analog Analog Dry Through, so your untouched guitar signal stays analog from input to output.
How do you update the Klowra Everlast firmware?
Firmware updates are done over the pedal's USB-C hardware interface on the top edge. Guitar Pedal X's Stefan Karlsson updated his unit twice, including the final launch firmware, and found it a very simple procedure, though he described the process as somewhat old-fashioned and clunky compared with app-based updaters.
Is the Klowra Everlast like the ALABS delay?
Guitar Pedal X's reviewer treats the Everlast as an evolved and improved iteration on the same core algorithms as the similar ALABS delay pedal, and in his 2025 round-up called it just about the best budget pedal you can get for delay. So the family resemblance is there, but the Everlast refines and extends what the ALABS unit started.
What power supply does the Klowra Everlast need?
It needs a 9V DC center-negative power supply drawing 250mA. That current draw is well past what a battery or a small daisy-chain output can comfortably supply, so plan on a dedicated 9V output from a pedalboard power supply capable of at least 250mA.
