POLTERBLAST MKI

Concept Art for a spectral amplifier 👻 🎻🔊

It reacts to spectral waves and turns them into colors and sounds. By converting them into humanly comprehensible signals, the PolterBlast™️ MKI gives a voice to beings and things that cannot be heard nor seen.
Here it is designed to make it sound like an ensemble of fretless basses, making it sound like a chaotic, ghostly acoustic concerto.
