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. 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.
