CRB Elettronica was an Italian electronic instrument manufacturer based in Ancona, in the Marche region. The company operated primarily through the 1970s and early 1980s, producing combo organs, synthesizers, drum machines, and auto-accompaniment units for a domestic market where Japanese and American imports were made scarce by a weak lira and steep import duties.

The brand is best known among collectors for its Diamond series of combo organs (including the 600, 700, 701a, 702, 730, 750, and flagship 800), and for a small catalog of rare synthesizers such as the Oberon dual-oscillator monosynth, the Voco Strings (an Italian take on the Roland VP-330 string/vocoder), and the Uranus 2.0. On the rhythm side, CRB built the Computer Band 2000 analog auto-accompaniment unit, the Computer Drums stand-alone drum machine with nine analog voices, and the earlier Rhythm Boy 480.

Production runs were small, and surviving units are uncommon. Several CRB instruments are preserved in the Museo del Synth Marchigiano, and the brand has a niche following in the vintage Italian synth collecting community. Schematics for the Cordovox CDX organ line also bear the CRB logo, pointing to OEM manufacturing relationships with other keyboard brands of the era.

CRB has 2 products cataloged on Equipboard, including Guitar Amplifier Cabinets and Synthesizers. Their gear is featured by 1 artist, with the strongest followings in Rock. Notable users include James Edward Bagshaw.
