We repair all synthesizer makes and models listed in the museum. We also calibrate models with available service manuals. Our bench charge is $64/hr (one hour minimum). Turn around time depends on the problem (complexity, parts, etc) and our backlog. We are a member of MITA (Musical Instrument Technicians Association) International and a Yamaha authorized service center. Contact us at firstname.lastname@example.org, describing the ailing synth, for more specific information.
