"Serial Nº 21196

Italian-made CRB “Diamond” Cavendish Combo 30 in remarkable condition for its age. Classic combo-organ tones plus a built-in “mini-band” (bass + drums) make it a fun, self-contained writing and performance machine. Built in Ancona under CRB’s Diamond/Cavendish line.

Organ section: Flutes, Clarinets, Reeds, Strings

Presets: Piano, Spinet, Harpsichord

Effects: Sustain and Vibrato (both sound great)

Mini-band (auto-accompaniment)

Drum patterns: Waltz, March, Tango, Bossa Nova, Samba, Slow Rock, Boogie, Disco — all with variable tempo/volume; very much in the vein of early CR-series drum machines.

Bass accompaniment with automatic chords, Free 1-Finger, Memory, and chord quality switching (Major default; Minor/7th via yellow/green buttons).

External output, headphone out
Expression pedal input
Built-in speaker that’s quaint yet surprisingly punchy
UK mains power - we can include a step-up/step-down transformer on request so you can use it in your country without modification, just ask for details."
