Allow JustPedals to introduce the Keeley Electronics Hydra Stereo Reverb & Tremolo Pedal

The Keeley Hydra combines two tone-enriching effects in one simple, pedalboard-friendly package. This feature-packed sonic workstation offers a range of high-fidelity reverb and tremolo algorithms that can add both space and dimension to your guitar, bass or synth sounds.

Following in the footsteps of their acclaimed Eccos 2-in-1 delay/looper, Keeley’s versatile Hydra pedal is the perfect companion for vintage aficionados who adore old-school ambient reverbs mixed together with traditional tremolo tones.

2 Effects in 1 Pedal

Hydra is split into two sides to reflect each of its sound engines, with independent Reverb and Tremolo footswitches making it easy to engage each of these effects or use them simultaneously. To alter the response of this killer tremolo/reverb combination, you can change their order to suit your specific tonal needs.

In addition, the Keeley Hydra’s ‘Alt Controls’ let you access in-depth parameters to shape the character of both engines. The pedal also offers an infinite reverb trail that’s perfect for creating dreamy soundscapes with, while the tremolo side’s footswitch doubles up as a tap-tempo function for syncing-up with a drummer or any musical accompaniment.

Reverb

A reverb pedal is like the rich sauce that ties every flavour on the plate into one smooth experience. It adds depth, warmth, and atmosphere — the sonic equivalent of a perfectly reduced glaze that lingers on the tongue. Whether you’re after the subtle ambience of a cosy café (spring or plate reverb) or the grand echoes of a cathedral (hall or shimmer reverb), this is where your tone breathes and expands. A touch of reverb can turn a dry sound into something lush and inviting — but pour on too much, and it’s all you can taste. Used with finesse, it’s the finishing touch that transforms your tone from plain to unforgettable.

Tremolo

A tremolo pedal modulates the volume of your guitar signal up and down in a rhythmic pattern, creating a pulsing or wavering effect that can sound vintage and hypnotic or sharp and choppy depending on the settings. It’s one of the oldest effects in guitar history, famously used on classic amps from the 1950s and ’60s.

Most tremolo pedals let you control the speed, depth, and wave shape, allowing you to go from smooth, subtle swells to intense stuttering tones. It’s a simple but expressive effect that adds movement and character to your sound.
