"According to our research, this Made In Italy piece was named the Crumar Bit 1 overseas."

this post:
"The Unique DBE was an American released version of Crumar's revered Bit 01 rack. Everything is exactly the same. 6 voice polyphonic analog synthesizer, stereo outs. So warm and such crazy, crisp fast envelopes. It is way warmer and phatter, and easier to program then let's say a Matrix 6. Lots of MIDI treats can affect many parameters with velocity and aftertouch like LFO, Pulse wave modulations and of course envelopes. Anything you see on the little matrix that has an extra frame around it is velocity sensitive. S/N is 0017. There can't be more than a few hundred of these. Much more rare than the Bit 01. These were available like for a few months back in the 80s."
