This foot switch is ideal for use as a sustain pedal
on any keyboard. Unlike other pedals that tend to never stay put, this one has a rubber
"gripper" bottom that keeps it in place. Some keyboards need a "normally open" switch
pedal, others need a "normally closed" switch - which is why a Roland pedal works
backwards on an Ensoniq keyboard, for instance. This new pedal has both! Just slide the
switch on the back to whichever setting your keyboard needs. Solid metal construction.
