an experiment with diy kalimba and zoom guitar fx processor.
the kalimba lays on a piezo pickup pad which sends the signal through two  plague bearer module linked together (they provide the filtering and self-oscillations). the fx pedal is set to remove the attack of the kalimba and delay the signal in an almost looping mode. there's also some compression to amplify the decaying notes and some reverb.
for more info on plague bearers look up plague bearer and flight of harmony. it is literally a beastly module.
