Keeley Caverns V2 Delay and Reverb Effects Pedal
Two of the most essential time-based effects — tape-voiced delay and three distinct reverb modes — in one hand-built, pedalboard-friendly package from one of the most respected names in boutique effects.
Who This Is For
The Keeley Caverns V2 was built for guitarists who want serious ambient capability without dedicating half their board to it. Whether you are a gigging guitarist looking to simplify your signal chain, a bedroom player building a first effects board, or a seasoned tone-chaser who knows the Keeley name and what it means — this pedal earns its spot. The delay side draws from Keeley's acclaimed Magnetic Echo circuit, delivering warm, tape-style echoes that sit naturally in a mix at any gain level. The reverb side gives you three genuinely different textures: the cluck and wash of a vintage blackface spring, the movement of a choral modulated hall, and the ethereal quality of shimmer — octave-voiced trails that open up under sustained notes in a way that few pedals can match. It is a used unit being offered here, so you are getting boutique American craftsmanship at a smarter price point.
Key Highlights
- Dual-effect design — independent delay and reverb engines in a single compact enclosure
- 650ms of analog-style tape delay based on Keeley's Magnetic Echo circuit
- Three reverb modes: Spring (blackface-style with tremolo), Modulation (choral/cavernous), and Shimmer (octave-up trails)
- Three-way delay modulation switch for adding Wow, Flutter, or clean repeats
- Switchable True-Bypass or Trails mode — tails ring out naturally after disengagement
- Top-mounted jacks keep your board layout clean and compact
- Hand-built in the USA by Keeley Electronics
- Powered by standard 9V DC center-negative supply
The Delay
The Magnetic Echo-derived delay circuit produces warm, slightly softened repeats that mimic the character of analog tape delay lines. The three-way modulation switch lets you run the repeats clean, add gentle wow and flutter for a vintage tape machine feel, or push into more dramatic pitch movement. Up to 650ms of delay time gives you plenty of range from tight slapback to long ambient trails.
The Reverb
Spring mode captures the drip and bounce of a 1960s blackface combo, complete with F-style tremolo for classic surf and country tones. Modulation mode wraps the reverb tail in choral movement, filling space with dimension. Shimmer mode layers octave voices into the decay — the kind of sound that can make a single held note feel like it is expanding into something much larger.
The Build
Keeley Electronics builds every pedal by hand in Edmond, Oklahoma, using high-quality components selected for tone and long-term reliability. The enclosure is compact without feeling cramped, and the top-mounted I/O jacks make it genuinely easy to drop into any pedalboard layout. The switchable Trails mode is handled via internal dip switch, giving you a clean exterior with real functionality underneath.
A Great Fit For
- Guitarists who want delay and reverb covered by a single trusted pedal
- Players building a fly rig or small board where space is at a premium
- Ambient, shoegaze, and post-rock players who need shimmer and modulated reverb textures
- Country and surf players after authentic spring reverb with tremolo built in
- Tone-conscious players who want boutique-quality effects without boutique-new pricing
- Anyone upgrading from a basic reverb/delay and ready for real control over their wet sounds
Sound and Use Case
The Caverns V2 is designed to sit at the end of a signal chain — after drives and modulation — where it handles the space and depth side of your tone. The delay repeats are voiced to blend naturally rather than cut through, which means they support your playing without competing with it. This is particularly valuable when running the delay and reverb simultaneously, since both effects are balanced to stack cleanly and create depth without turning into wash.
Trails mode is the right call for most live applications, letting reverb and delay tails decay organically when you stomp the effect off mid-song rather than cutting abruptly. True-bypass mode is there for players who prefer the cleanest possible bypass signal. Either way, the Keeley buffer is engineered to maintain signal integrity throughout the chain.
Specifications
If you have spent any time chasing ambient tones, you already know that reverb and delay together can be either magic or a muddy mess — and the difference usually comes down to how well the two effects are voiced to work with each other. That is exactly what Keeley spent two years getting right with the Caverns V2, and it shows every time you engage both sides at once.
This is a used unit, which means you get the full quality of a hand-built American boutique pedal at a price that just makes sense. Whether it ends up as your board's anchor or the piece that finally frees up space for something else, the Caverns earns its keep.
