The HYDRA combines high-fidelity Reverb and Tremolo to add space and dimension to your guitar, bass, or keyboard signal. After the team at Keeley completed the ECCOS, we wanted to craft the perfect companion pedal, the tone of which had to make it impossible to turn off.

Keeley Hydra Stereo Reverb TremoloBathe your sound in Spring, Plate or Room Reverb, then add tap-tempo enabled Harmonic, Vibrato, or Sine Wave Tremolo with the press of a button. You can easily change the order of effects or the character of the Tremolo or Reverb with the HYDRA’s smart Alt Controls. You can even create an Infinite Hold Reverb Trail!

Save up to three presets with ease using our intuitive save feature. Engage Reverb Trails on the fly, no more internal dip switches. The Hydra can be used with pro remote switching systems and offers both TRS Expression Pedal and External Tap-Tempo inputs.

The HYDRA is a complete end-of-pedalboard solution that fits perfectly in any musician’s rig, regardless of genre. Experience next-level processing power in this pedalboard-friendly enclosure. The sky, or more appropriately, the ocean floor, is the limit with the new Keeley Electronics HYDRA!

  1. gordon

    This thing is amazingly powerful. Not does it have 3 types of modulation AND 3 types of stereo reverb, but it also has 3 storable presets, expression pedal input, but it also has tap tempo, the ability to do wet/dry outputs, and lots more parameters. Sounds great too!

    The Stereo Reverbs are something easy to get lost in, in a good way, while I haven’t even explored all it can do, tap tempo tremolo, presets, everyone that tries it is impressed by the sound, especially my FIL who always asks “what is that?” He likes playing surfy stuff, and I ordered a Keeley custom shop version, with just a photograph I chose, they laid it on the pedal for a custom 1of1 Hydra. Friends have also said that they were able to move about 3 pedals off their board with all the features this hydra provides and its size.
