Cabinets and Cases


Cabinets are available for all instruments, but it is recommended that if you may consider "expanding" your Glass Harmonica's range in the future, you purchase a cabinet only for the larger instrument.

Please note that cabinets, cases and enclosures cannot be accepted for credit at any later time towards larger cabinets, cases or enclosures.

Cabinets are made to order for each individual instrument, and the height of the support legs can be specified to accommodate a player's foot- to - knee height and playing position.

Cabinets vary in length according to the size of the instrument.The support legs are removable and all electronics and mechanical parts are concealed.


Black, foam lined travel cases come with straps that hold down the base panel of a Portable Model, two locking and two padlock hasp locking side pieces, and two recessed end handles. Available in lift-off or hinged design.
An area can also be made to house the speed control and / or accessories such as foot pedals
Prices depend on the size of the instrument and cushoning/shape.
Please inquire when ordering.
