Excaliber 96 bass chromatic accordion, 68 treble buttons, C system. Three sets of treble reeds with musette, 7 treble side register switches. Two bass side register switches. Comes with hard case on wheels. This is a very good accordion in good condition and has been checked over and tuned up recently. I play piano accordion and just don't have the time to learn and play the chromatic. Located in Sidney on Vancouver Island.
