KavernPlate Reverb / Freeze
Kavern is a stereo plate reverb voiced after the great studio plates: lush, dimensional and bright, with every part of the tail in your hands. Then the Freeze footswitch turns the reverb into an instrument, holding chords and notes in suspension for drones you can play over.
Switch 2 · Size
Pick the size of the plate
The Size switch sets how big the virtual space is. Flip it to see the same note bloom into a tight room or a long, open tail.
Select
Half the standard size. Tighter and more focused, for reverb that sits close to the note.

Every Keystone pedal shares the same small enclosure, MIDI control, APEX expression and free firmware updates, so they work together on one board. Its LED glows dark blue, its signature color.
