We are a custom effects shop located in
Boston, Massachusetts, USA and specialize in building and modifying guitar pedals. Our blog includes some additional information on the projects we've worked on that didn't quite have a place on our main page. The gallery is quick glimpse of our favorite past projects. Follow us on Facebook for more frequent updates of things that may not make it on the official FXdoctor page and join our newsletter for promotions and sales.
