This handmade synthesizer is played by touching the large contact and one of the 8 smaller contacts. Each contact plays a higher pitch. It is monophonic and will sound the highest pitch being played.
There is a built in LFO effect that ranges from a slow pitch shift, to a fast modulation, to an almost distorted throaty sound. You have controls for the speed of the LFO and a switch to enable it. A red power light flashes in sync. There is also a volume control.
A fun note, this works by using the human body as a bridge so it can be played with a friend creating a human chain.
The 1/4″ output makes it easy to connect to amps, effects, or recording equipment. It is powered by a 9volt battery.
