A plain sheet metal underside to attach your own mounting material.
The Fulcrum pedal comes with a plate mounted to the underside that sports a special kind of rubber which makes the pedal stand firmly in place. Some players however prefer to mount the pedal to a pedal board by use of dual lock, screws, special mounting brackets, etc. In that case please get this option and feel free to modify as needed without touching the very pedal.
The blank is made from 3mm aluminium with all the right cutouts. Of course it’s deburred and countersunk holes to attach the pedal.
