Three oscillator "synth". Construction by Audun Eriksen.
Circuit drawing by me, but I have loaned some pics from Worthekik.

The cd box to the right is made at a workshop with Audun in 2006, and the butter box is made 14th of May, 2010.

Note: with this setup, the potentiometers have the following oscillator settings, from left to right: midrange, bass, treble.
It is also possible to change the potentiometers to whatever you want to use,
like LDR. I'll recall that Audun used rca-contacts for switching between different controls.
