Marsona 1200a Analog Noise Generator

This Marsona 1200 (Alternately branded as the Invento Sound-x) is fully functional and in good condition.

The Marsona 1200a is an analog noise generator with a simple filter to create different noise colors (white to pink), as you would find on an analog synthesizer. The noise is modulated to simulate rain, waterfalls, and surf. There is a knob to select between these sounds, as well as knobs to change the surf rate, surf range, tone, and volume. There is an on-board speaker or the sound can be amplified through the 1/4" output. Start a noise/drone band or catch some Z's!
