Plug a guitar in and rock it :) Because there are many questions: This is NOT a good speaker to _play_ music but likely a good one to _make_ artful music. This is, how music instruments work: You stroke a string on your guitar and what you will get to hear is mostly imperfection in the amplification of the vibration of that string. That's why pianos sounds different from guitars or trumpets. A perfect music instrument with no imperfections would only sound sine waves with no overtones. A simple school flute or smoke alarm is very close to that. And the same is the case here: The "music instrument" you see in the video consists of two parts: 1. Some simple playback mechanism (likely like the audio chip from a cheap 80's fake-pendulum battery wall-clock which uses square-wave oscillators) 2. This (judged by fidelity) horrible box of warning horns totally wrecking the audio signals into this unique chime sound. :-) I think, it would do a good guitar amplifier.
Ladies and gentlesirens, due to no visual site of the MC controller being present, the 6 horned speaker must only do with an old ass radio amplifier until further notice. We apologize for the inconvenience. We'll keep you all updated as soon as we hear anything more from the current status of the MC. Thank you all for your patience.
