We offer a wide  range of services on vintage synthesizers and keyboards from basic cleaning, tuning and maintenance to full service repairs, refurbishing, and restorations. We offer free estimates and can contact you with several repair options, usually within a week of getting your instrument in the shop.  We will consult with you before doing any repairs. We use factory and original parts whenever available.

“ Being a vintage synthesizer player and enthusiast myself, I am very much into the repair and restoration of these instruments. With over 30 years of experience with them, I have been around most of these instruments since they were new, and I understand how they should sound and feel.

Servicing these instruments can be very challenging due to age problems and parts availability, but a properly restored and calibrated vintage synthesizer is worth every effort.......”
