I'd seen modular synths on the net but never really used one or understood how they worked when I built this. Its got a 4 channel audio mixer, ring modulator, 555 oscillator, light controlled oscillator, tape recorder with pitch control, fan oscillator and an audio splitter. It taught me a lot about audio circuits and I still use it today.

The 9VLT was a one off creation. If you would like to talk about commissioning me to make something similar please shoot me an email at firstname.lastname@example.org.
