Bathe your sound in spacious reverbs and rich tremolos!

The HYDRA combines high-fidelity Reverb and Tremolo to add space and dimension to your signal.

Bathe your sound in Spring, Plate or Room Reverb, then add Harmonic, Vibrato, or Sine Wave Tremolo with the press of a button.

You can easily change the order of the 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 the pedal's 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!
