CRB Computer Band 2000 groovebox synthesizer ultra rare prototype 1978? Black

The CRB computer band is one of the rarest instruments ever made. A complete rhythm drum computer with 20 different rhythms (made of presets), a double octave bass line synthesizer and four different sections: one for bass (double bass, bass guitar, and tuba) , two different 'chord' section accompaniment, and an arpeggio presets section. all of them with single decay and volume action. It was made by the Italian company CRB as a full compact musical instrument by itself. 
Very well made (Supposedly by the end of the decade of the '70s) and heavy weight (aprox. 13kg) Only few units made and almost impossible to find in any condition. 

This particularly unit is in excellent cosmetic condition and 95% working condition (Rhythm machine, bass line, chord section) Only the arpeggio mode sounds keep 'on hold'. it may be a contact problem. 

It is sold as it and I will ship anywhere in the European Union.
