At Bell Tone Synth Works, we specialize in vintage synthesizer repair, restoration and service, and also work on vintage sequencers and drum machines, vintage analog effects units including tape echos, electronic “combo organs” and certain other keyboards, and vintage electric pianos (Rhodes, Wurlitzer, Clavinets, etc).  We work on vintage instruments only and in general, we do not work on any instrument made after 1990. We also do not work on console or theater organs.

One of our core values is that we aim to take all of our repair projects as far as possible in the direction of restoration. That means that we strive to go the extra mile to improve the long-term reliability of your instrument in addition to fixing the issues that it may have now. However, we do what we can to work with you to come up with a plan for your instrument’s service that works with your budget.

Our available services for vintage instruments include:

• troubleshooting and repairs
• routine service/maintenance
• calibration and tuning
• power supply upgrades
• MIDI retrofit and other upgrade kit installations
• cosmetic restoration

Brands of equipment that we work on frequently include:

We also offer design services for custom analog interface devices and synth modifications, while also working on our own synth modification, upgrade and design projects.

Here are some of the custom and design projects we’ve been working on lately.
