Fridgebuzzz, an Electronic manufacturer created a one of a kind synthesizer. Using an old Atari400 case completely strip it, and fill it with new electronics. Now it is a 12 oscilator and 3 modulator square wave synth. The fact that the keys are old-style arcade push buttons make my heart skip a beat.
Unfortunately it is a one of a kind, but they are working on a portable version. Frankly I couldn’t care less about the synth specs in there. I’d just create a little shrine in my studio and put this behind bullet-proof glass.
