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.

6 Sounds in Total!

Keeley’s Hydra pedal comes equipped with gorgeous Spring, Plate and Room reverb algorithms, plus tap-tempo enabled Harmonic, Vibrato and Sine wave tremolo sounds. All of these effects are accessible at the press of a button, and Hydra even allows you to save and store 3 of your favourite presets for instant recall.

Additional Features

With expression pedal control, remote bypass, analog-dry-through, kill-dry and a ridiculously low power-draw – the Keeley Hydra is sure to add immense flexibility and stunning sounds to any rig.

Keeley Electronics

In the current JustPedals catalogue, Keeley Electronics is represented by Overdrive Pedals, Compressor Pedals and Fuzz Pedals. Current listings include Keeley Fuzz Bender, Keeley Katana Mini and Keeley Compressor Pro. That makes the range relevant to players looking for drive, gain and clipping, plus time-based effects and ambience. Check each model for its exact circuit or processing platform, controls, power requirements and connections, particularly where the catalogue includes both pedals and supporting gear.

Tremolo & Vibrato Pedals

Tremolo and vibrato pedals create movement by changing amplitude or pitch. Tremolo varies volume, while vibrato varies the pitch of the signal; combined units may add harmonic, bias or rotary-style voices. Rate, depth, waveform, phase, mix and tap tempo shape the feel, from gentle pulse to pronounced rhythmic interruption. Check whether the effect is placed before or after drive, whether it preserves the dry signal, and whether stereo or expression control is available for a more animated setup.

Bass

Bass products are designed or voiced to retain low-frequency information and usable headroom with bass guitar or other low-register sources. Controls may centre on clean blend, low-end EQ, compression, crossover points or drive character. A guitar pedal can sometimes work well on bass, but it may remove the fundamental or compress the transient. Check the frequency response, input impedance, output level and dry-signal path with the intended tuning and amplifier.

Reverb

Reverb creates a field of reflections around the dry signal to suggest a room, plate, spring, hall or other space. Decay controls length; pre-delay separates the attack from the ambience; damping, tone, diffusion, modulation and mix shape size, brightness and movement. Short settings add depth without washing out a part, while long tails become a deliberate texture. Check trails, spillover, stereo routing, presets and headroom when placing reverb after gain or delay.

Stereo

Stereo products provide separate left and right audio paths, which may widen modulation, preserve independent delays or route a pedalboard into two amplifiers or a mixer. Input and output behaviour is not always symmetrical: some units sum a stereo input, while others create stereo from a mono source. Check whether the effect collapses safely to mono, how the dry signal is routed, the socket format and the destination’s panning and phase requirements.
