As a guitarist, I’ve spent more years than I care to admit on a quest. It’s a familiar journey for many of us: the search for the perfect ambient texture. We chase that elusive combination of echo and atmosphere that can turn a simple chord progression into a cinematic soundscape. For years, my solution was a sprawling pedalboard, a complex tapestry of individual reverb and delay pedals, each with its own power supply, patch cables, and quirks. It was powerful, yes, but also cumbersome, prone to signal loss, and an absolute nightmare to transport. The real problem was the “tap dance”—trying to engage a specific delay time and a lush reverb simultaneously mid-song. It was a constant battle between creativity and practicality. This struggle is precisely why a high-quality, dual-effect pedal isn’t just a convenience; it’s a creative liberation, promising to deliver that expansive sound without monopolizing precious pedalboard real estate.

What to Consider Before Buying a Combined Reverb and Delay Pedal
A dual reverb and delay pedal is more than just an item; it’s a key solution for streamlining your signal chain and unlocking new creative possibilities. It solves the fundamental problem of creating depth and dimension in your guitar tone by combining the two most essential time-based effects into a single, cohesive unit. The main benefits are efficiency—saving space, power outlets, and money—and synergy. A well-designed dual pedal ensures the reverb and delay voicings are crafted to complement each other, eliminating the guesswork of pairing disparate units. This integrated approach allows for the creation of complex, layered soundscapes that might be difficult to achieve otherwise, from subtle slapback echoes with a hint of room reverb to vast, shimmering ambient washes.
The ideal customer for this type of product is the gigging musician, the home studio enthusiast, or any player looking to maximize their sonic palette while minimizing their setup’s complexity. If you play ambient, post-rock, worship, or any genre that leans heavily on atmospheric textures, a pedal like the Keeley Caverns V2 Reverb and Delay Pedal is a game-changer. However, it might not be suitable for sonic purists who demand a separate, highly-tweakable analog delay and a genuine spring reverb tank. Additionally, players who require advanced features like MIDI control, extensive presets, or stereo inputs/outputs might need to look at larger, more complex digital workstations. For those on a tight budget or just starting, a pair of more affordable mini-pedals could be a viable entry point into the world of time-based effects.
Before investing, consider these crucial points in detail:
- Dimensions & Space: Pedalboard real estate is invaluable. A dual pedal’s primary advantage is its compact footprint. Measure your available space carefully and compare it to the pedal’s dimensions (the Caverns V2 is 6.75 x 4.3 x 3.25 inches). Consider not just the width and length, but also the placement of jacks—top-mounted jacks can save significant space compared to side-mounted ones.
- Capacity/Performance: This refers to the sonic capabilities. For delay, what is the maximum delay time (the Caverns V2 offers 650ms)? Does it have modulation? Is there a tap-tempo feature? For reverb, how many algorithms are included? The Caverns V2 offers three distinct modes—Spring, Shimmer, and Modulated—which provides significant tonal variety.
- Materials & Durability: Gigging musicians need gear that can withstand abuse. Look for pedals with a sturdy metal enclosure, like the aluminum alloy housing typically used by Keeley. High-quality footswitches and firmly-seated knobs are also indicators of a well-built pedal that will endure years of stomping and travel.
- Ease of Use & Maintenance: A great pedal should be intuitive. Can you dial in a good sound within seconds, or do you need to spend hours with a manual? The Keeley Caverns V2 Reverb and Delay Pedal features a clear layout with dedicated knobs for each function, making on-the-fly adjustments simple. Also consider power requirements; the standard 9V DC center-negative input is crucial for compatibility with most pedalboard power supplies.
Understanding these factors will ensure you choose a pedal that not only sounds great but also integrates seamlessly into your existing rig and workflow, providing a reliable creative tool for years to come.

First Impressions: Studio-Grade Ambience in a Road-Ready Box
Unboxing the Keeley Caverns V2 Reverb and Delay Pedal is a satisfying experience. The pedal arrives in a sturdy, well-designed box, and upon opening it, the unit itself immediately feels substantial and professional. The crisp white finish is clean and modern, providing excellent contrast for the black text, making the controls legible even on a dimly lit stage. Weighing in at just over a pound, it has a reassuring heft without being overly heavy. The knobs turn with a smooth, firm resistance that inspires confidence—there’s no wobble or cheap plastic feel here. It’s a testament to Keeley’s reputation for high-quality construction.
Compared to its predecessor, the V1, this version feels more refined. The layout is intuitive, with the delay controls on the left and reverb on the right, each with its own dedicated footswitch. This simple separation is a huge ergonomic win. Plugging it in for the first time, what struck me was the silence; the pedal is remarkably low-noise, even with a high-gain amp setting. The internal switch for True Bypass or Trails mode is a professional feature we expect at this price point, and it’s a crucial addition for players who want their effect tails to decay naturally after switching the pedal off. It’s clear from the first five minutes that this isn’t just another effect pedal; it’s a thoughtfully designed musical instrument, ready to inspire new sonic explorations right out of the box.

Performance Deep Dive: Crafting Atmospheres with the Keeley Caverns V2
After spending considerable time with the Keeley Caverns V2 Reverb and Delay Pedal, both in our studio and integrated into a live performance rig, we can confidently say it’s a powerhouse of ambience. This is not simply two separate effects crammed into one box; it’s a cohesive ecosystem of sound that encourages experimentation and rewards thoughtful tweaking. Its true strength lies not just in the quality of the individual effects, but in how beautifully they interact to create deep, immersive, and musical textures.
The Analog Heart: Exploring the Tape Delay Engine
The left side of the Caverns V2 is dedicated to its delay circuit, designed to emulate the warm, slightly imperfect character of a vintage tape echo machine. With controls for Time, Repeats, and Level, dialing in a basic echo is straightforward. The magic, however, lives in the fourth knob: Modulation. Engaging this control introduces a gentle, shimmering pitch-shifting to the repeats, perfectly mimicking the “wow and flutter” of an old tape loop. We found that keeping the modulation subtle (around 9 o’clock) adds a gorgeous, three-dimensional quality and movement to sustained notes, making them feel alive. This was echoed by one user who praised its “killer old school slapback/tape delay w/ wow&flutter.” Pushing the modulation further ventures into seasick, chorus-like territory, which can be fantastic for experimental or lo-fi textures.
The 650ms delay time is more than enough for classic slapback, rhythmic rockabilly echoes, and Edge-style dotted-eighth note patterns. While some ambient players might wish for multi-second delay times, we found the 650ms range to be a musical sweet spot that prevents the sound from becoming an undefined, muddy wash. It forces a certain discipline, encouraging the creation of rhythmic patterns rather than just endless pads. We were particularly impressed with how the repeats degrade. They don’t just fade in volume; they lose a touch of high-end fidelity with each echo, just like real tape, which helps the delay sit perfectly behind your dry signal without ever overpowering it. This authentic analog character is a feature that truly sets it apart from sterile digital delays.
A Trinity of Ambience: Spring, Shimmer, and Modulated Reverbs
The reverb side of the Keeley Caverns V2 Reverb and Delay Pedal is where its versatility truly shines, offering three distinct and beautifully voiced algorithms selected via a small toggle switch. Each mode transforms the character of the pedal, making it feel like three different reverb units in one.
- Spring Mode: This is a fantastic emulation of a classic tube amp spring reverb tank. It has the characteristic “drip” and “splash” that surf and blues players adore. We found it incredibly dynamic; play softly and you get a subtle sense of space, but dig in hard on a note and the springs react with a satisfying crash. The ‘Warmth’ knob is key here, allowing you to dial in the bright spank of a 60s amp or a darker, more mellow tone. It’s an authentic and highly usable spring sound.
- Modulated Mode: Switching to this mode adds a rich, chorus-like effect to the reverb trails. This is the secret weapon for creating deep, lush soundscapes. We used it to turn simple arpeggios into swirling, orchestral pads. The modulation is elegant and never overbearing, adding a constant sense of movement that prevents the reverb from sounding static. It’s perfect for adding a touch of 80s nostalgia or for modern worship and ambient styles.
- Shimmer Mode: This is arguably the crown jewel of the reverb section. The Shimmer effect adds octave-up harmonics to the reverb’s decay, creating an ethereal, angelic choir-like sustain that hangs in the air. This effect can be overdone on lesser pedals, sounding thin and synthetic. Keeley’s algorithm, however, is stunningly musical. One user perfectly described the sound as “angelic” and “beautiful,” and we wholeheartedly agree. By carefully balancing the ‘Blend’ and ‘Decay’ knobs, we could create subtle, halo-like textures or go full-on for immense, synth-pad swells that felt like they could sustain forever. It is an inspiring sound that practically writes song parts for you.
Intuitive Control and On-Stage Practicality
For all its sonic complexity, the Keeley Caverns V2 Reverb and Delay Pedal remains incredibly easy to use. The decision to give each effect its own footswitch is brilliant. You can use the delay by itself, the reverb by itself, or engage both simultaneously. This independent operation is a massive advantage over pedals that force you to use both effects at once. The layout is clean and logical, with no hidden menus or confusing multi-function knobs. What you see is what you get, which is a blessing in a live performance setting where you need to make quick adjustments between songs.
The internal switch for True Bypass or Buffered/Trails mode is another crucial pro-level feature. In True Bypass mode, the pedal is completely removed from your signal chain when off, preserving your pure guitar tone. However, switching to Trails mode was our preferred setting. This allows the reverb and delay tails to decay naturally even after you switch the effect off, preventing abrupt, unnatural cutoffs. This is essential for smooth transitions and creating seamless ambient washes. This level of professional consideration demonstrates that Keeley understands the real-world needs of performing musicians, making this pedal a reliable and practical tool, not just a studio toy. You can see its full feature set and user reviews to appreciate the thoughtful design.
What Other Users Are Saying
After our own extensive testing, we explored feedback from a wide range of users, and the sentiment is overwhelmingly positive, confirming our findings. Many players, like one who noted the pedal had “ridiculous versatility and gorgeous sounds,” are blown away by the sheer quality and variety of tones packed into such a small enclosure. The praise for the individual effects is specific and consistent; the “killer old school slapback/tape delay w/ wow&flutter” and the “clear, warm spring reverb” are frequently highlighted.
The Shimmer effect is a standout feature for many, with one musician calling it “beautiful” and another, who uses it to write reggae, describing the pedal’s overall sound as “angelic.” This feedback underscores the pedal’s ability to transcend genres, proving it’s not just for ambient post-rockers. The consensus is that the Keeley Caverns V2 Reverb and Delay Pedal is a professional-grade tool that inspires creativity and is worth the investment. While we found one user who mentioned a minor issue with a promotional card, their review still concluded that the pedal itself is “totally awesome” and a “great reverb and delay pedal,” which speaks volumes about the product’s core performance.
How Does the Keeley Caverns V2 Compare to the Competition?
The market for dual-effect pedals is competitive, but the Keeley Caverns V2 Reverb and Delay Pedal occupies a sweet spot of quality, versatility, and size. To provide context, let’s see how it measures up against three popular alternatives, each catering to a slightly different player.
1. Donner Reverb Delay Pedal 2 in 1
- [2-in-1 Pedal]: The 2-in-1 Revecho pedal seamlessly integrates meticulously chosen delay and reverb effects, offering musicians a powerful combination of tonal possibilities in a single, compact pedal
- [Instant Precision Control]: Adjustable effect level, delay time, delay feedback, reverberation time, makes it suitable for every music genre
- [Tap Tempo]: The Tap Tempo function provides instantaneous control over delay time, allowing you to effortlessly sync your effects with the rhythm, making it an ideal choice for live performances and...
The Donner Revecho is a compelling budget-friendly option. Its biggest advantage over the Keeley is the inclusion of a Tap Tempo function for the delay, a feature many rhythmic players will find indispensable. However, this comes at a cost to sonic quality and versatility. The Donner’s single “Reverb” mode is a simple digital algorithm that lacks the nuanced character of the Keeley’s Spring, Modulated, and Shimmer options. While the Donner is a fantastic entry point for players on a tight budget or those who absolutely need tap tempo, musicians seeking premium, boutique-quality tones and greater atmospheric variety will find the Keeley Caverns V2 to be a significant step up in every respect.
2. Walrus Audio Slö Multi Texture Reverb

- Rise – this is an auto-swell reverb for beautiful cinematic swells. Don't rush it. Let it breathe and gently wake up. X knob sets the amount of time It takes the reverb to swell in after a note is...
The Walrus Audio Slö is not a direct competitor, as it is a dedicated reverb pedal, but it’s often considered by players in the ambient space. The Slö is a specialist, focusing exclusively on creating vast, ethereal, and experimental reverb textures with its Dark, Rise, and Dream modes. It offers deeper control over modulation and texture within its reverb engine than the Keeley. A player who wants the absolute most immersive and tweakable ambient reverb and plans to use a separate, dedicated delay pedal might prefer the Slö. However, for the guitarist who needs a complete, all-in-one ambience solution with both high-quality delay and multiple reverb voicings in a single pedal, the Keeley Caverns V2 Reverb and Delay Pedal offers far greater overall utility and value.
3. Caline Snake Bite CP-26 Hall Reverb Pedal
- Experience three types of delay: digital, analog, and tape delay modes
- Easily control the delay with adjustable time, repeat, and level settings
- Enjoy high-quality sound with the True Bypass foot switch that ensures a crystal-clear signal
The Caline Snake Bite represents the ultra-budget end of the spectrum and is a dedicated reverb pedal, not a dual-effect unit. It offers a simple, single Hall reverb algorithm with a handful of controls. While it can certainly add a sense of space to your tone for a very low price, it is in a completely different league from the Keeley. The Snake Bite lacks the multiple reverb modes, the pristine audio quality, the robust build, and of course, the entire delay side of the Caverns V2. The Caline is suitable for a beginner building their first pedalboard on a shoestring budget, but any serious player will immediately appreciate the professional-grade sound, versatility, and durability of the Keeley.
Our Final Verdict: Is the Keeley Caverns V2 Worth It?
After countless hours of playing, tweaking, and performing with the Keeley Caverns V2 Reverb and Delay Pedal, our conclusion is unequivocal: this is one of the best dual-effect pedals on the market for players who prioritize pristine sound quality and musical versatility in a compact form factor. It expertly combines a warm, characterful tape-style delay with a trio of stunningly beautiful and distinct reverb algorithms. From vintage spring splash to angelic shimmer pads, the Caverns V2 delivers professional, studio-grade tones that are both inspiring and immensely usable.
While the lack of tap tempo may be a deal-breaker for some rhythm-focused players, we found the musicality and texture of the delay more than compensated for it. This pedal is built for the discerning guitarist who wants to streamline their pedalboard without compromising on their atmospheric effects. It’s for the songwriter who needs an “always-on” touch of space, the ambient artist crafting cinematic soundscapes, and the gigging musician who needs a reliable, road-worthy tool. If you’re seeking to elevate your tone with rich, immersive, and beautifully crafted ambience, the Keeley Caverns V2 is an exceptional investment that we can’t recommend highly enough.
