Keeley Caverns review | 2 incredible pedals in 1

The Caverns V2 isn’t a reverb pedal or a delay pedal, it’s both. Welcome to the ultimate Keeley Caverns review.

Keeley Caverns review

The Caverns V2 isn’t a reverb pedal or a delay pedal, it’s both. From traditional spring reverb sounds to an all-out psychedelic odyssey, this pedal can do it all. And all with beautiful sound quality.

I’ve had the pleasure of owning one for over a year now, and I wanted to share my experience with the pedal and create the ultimate Keeley Caverns review.

It’s highly intuitive and has a huge abundance of usable sounds in one, expertly built box.

Developed by Keeley Electronics, a company known for its dedication to creating top-tier guitar gear, this pedal has garnered widespread acclaim, becoming a favorite among guitarists seeking ethereal soundscapes and captivating textures.

I’ve played guitar for over 25 years, and I’m a massive fan of reverb. And yes I’d class this as a reverb pedal. But a unique reverb pedal. Yes, it can be treated as a tape-style delay pedal, and potentially save space on your pedal board, but it’s when combining the delay channel with the reverb that the magic really happens.

Rise of Combined Reverb & Delay Pedals

Around 2017/2018, when the Caverns V2 came out, the music gear industry witnessed a surge in the creation of combined reverb and delay pedals. While the concept of having both effects in one unit wasn’t entirely new, it was the Caverns V2, that could be credited with starting this off.

This pedal’s success encouraged other companies to follow suit and create their own versions, sparking a trend in the market.

What is the Caverns V2

The Caverns V2 is a remarkable reverb pedal and delay pedal that combines versatile reverb modes and tape-style delay.

It offers three reverb modes: Spring Reverb mode for vintage Blackface-style reverb with two other reverb modes. Shimmer Reverb mode adds octave-up voices to the effect. While Modulation Reverb mode adds a chorusing effect to a cavernous reverb.

And on the delay side, there’s an increidble tape-style delay with wow/flutter modulation and up to 650ms of delay time.

I’m a huge fan of Keeley products, never having owned one that disappointed me. And the Caverns is no different. It delivers exceptional sound quality and control, making it one of the best reverb pedals I’ve ever played.

My personal Keeley Caverns review

The headline news is the sound quality. While the pedal is entirely digital, its sounds are studio-quality and so close to analogue that if anyone said they could tell the difference, they’d probably be lying. And that’s good enough for me, and for anyone else not wanting to carry a real spring tank around with them.

I love how it takes seconds to dial in a great sound and how intuitively you can tweak the pedal to adjust to what’s in your head. This experience means that I’m always focussed on the guitar part I’m playing, and not overly distracted by the pedal and it’s settings.

User-Friendly Controls for Easy Navigation

Despite boasting eight knobs, two ports for footswitches, and two 3-way toggle switches, the Caverns V2 remains remarkably user-friendly. With the reverb controls on the left and delay controls on the right, navigating the pedal’s settings becomes intuitive, allowing guitarists to find their desired sound with ease.
