HYDRA STEREO REVERB & TREMOLO
THE KEELEY HYDRA - STEREO REVERB & TREMOLO
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, and we did just that with our new, feature-rich
blue box. Bathe 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!
