Whew! Thank god it’s Not the Bass version. One thing of note. I would imagine a fully functional unit is rare considering the fragility of the electronics. There was /is a guy making replicas so I’d go over that one with a fine tooth comb. It’s only 140 miles down the road but i do not want the guitar version. Around that time (early 70’s) I bought the Lite Box version from Radio Shack. I think the circuitry was similar. One color pulsed with the treble frequencies, another color for midrange, and a third color for bass. Did the Ricks flash randomly or were they frequency-specific?
