The Grace Speed Control
The Grace Speed Control is a universal foot pedal replacement. It works with many machines on the market. The easily accessible setting adjustment allows you to have compatibility with multiple machines. With Grace Speed Control, when you switch machines it will too! The Grace Speed Control is compatible with many DC-powered machines that have a single prong foot pedal plug-in. D.C.-powered machines usually have a separate foot pedal plug-in and a power cord plug in.
(AC-powered machines combine the two cords into one plug--these types of machines are generally NOT compatible with the Grace Speed Control).
