Cavagnolo piano accordion with 41 treble Keys and 120 bass buttons.  

Super light reedless accordion with very attractive and distinctive appearance.    This accordion also comes with a radio transmitter so is completely cable free (contains rechargeable batteries).  There is a huge range of accordion sounds available from this instrument and it can also power any midi expander in addition.  The accordion is programmable and data can be dumped to an external device if required.  This model is finished in the expensive Ambiance de Mer pictorial colour scheme.  The instrument has only had very light use.

This kit is extremely portable as the sound module / radio receiver and associated parts are all very compact - you only need to provide the amplifier (will work with many domestic amplifiers also).

All in very good working order - buyers should satisfy themselves as to the description before ordering as descriptions are subjective.
