Bell Tone Synth Works – Philadelphia

Bell Tone Synth Works LLC was established in Philadelphia, PA in 2016 by owner and senior technician Alison Stout. In just a few years, Bell Tone Synth Works has developed a reputation as one of the best synth tech shops in the country. We are committed to providing thorough, detail-oriented repair and restoration work combined with friendly, responsive and transparent customer communication. Thanks to the value we place on truly understanding how analog and vintage digital systems work and the time we constantly invest in expanding our knowledge, we have also become known for succeeding in fixing troublesome issues where other techs have failed.

On the company’s website you can read a blog about recent repairs and projects, such as Sound Selection on a CS80, restoring the saddest Minimoog in the world, EML 101 and EML 100 V/Octave mods, and many more.

Besides synth repair services, Bell Tone Synth Works also has a shop with modification and protection kits for your synths, and they have vintage synths for sale too …


Alison Stout, owner and technician is a classically-trained musician with over 10 years of electronics repair experience.  After graduating from college with a B.A. in music composition, her interest in orchestration led her to an interest in synthesis and a love of classic analog sounds. Finding herself increasingly fascinated by analog electronics theory, she devoted much of the next decade to its study before opening Bell Tone Synth Works in 2016.

Darian Scatton, technician began studying electronics, restoring combo organs and building modular synths in 2013. Looking for a change in direction after years of working as a web developer and programmer, he joined Bell Tone Synth Works in 2017.  He is also a lifelong musician and classically-trained harpist.

Joe Alesi, technician joined the team in 2018 after having previously worked for local effects pedal company Smallsound/bigsound, and is also an experimental electronic musician active on the Philadelphia music scene.
