Hand wired “piezo pre-amp” with custom made piezo element. This is a great way to get into electro acoustics and surface sound experimentation.
Amplify just about anything that vibrates. Drop the piezo element in water for hydrophonic sounds and effects. Put it in your mouth and get weird with it. Endless possibilities await.
Comes with a waterproof piezo element wired to a 1/4″ Hosa brand cable, approx. 2.5 feet long.
Knob controls gain.
LED is a Blue Super Bright.
9 volt, center negative – battery to 2.1 included.
(most guitar effects power supplies will work).
