You've heard this famous effect in hits and live concerts, popularised by Peter Frampton, Joe Walsh, Slash, Aerosmith, Alice In Chains and others. The sturdy metal casing houses a phenolic diaphragm speaker, powered by your amplifiers external speaker jack. (Place it in line with your external, speaker, which can remain connected).
A 6 1/2 foot surgical tube carries the diaphragm speakers sound to your mouth. The tube end is placed near a voice microphone. By shaping sounds (or even "words") with your mouth, you immediately achieve startling vocal-like sounds that you can manipulate into incredible organic tones. The effect's blended signal is the output of your voice microphone.
Controls: Footswitch toggles unit active/inactive • Surgical quality plastic tubing allows natural "voice" modulation of played notes.
