PedalPusher is a family of extremely light-weight yet rugged extended-range pedals.  Expression and Volume variants are available; this is the Expression Pedal page.  An expression pedal is a data entry device; your signal does not pass through it.  It is used for controlling the internal parameters of the device it is connected to.  It has a single 1/4" TRS jack for connection to any expression pedal jack on the back of your keyboards or stomp boxes.

PedalPusher rotates through a full 30 degrees, so you can make small changes more accurately, or large changes more smoothly.  Most other expression pedals rotate through only 15 degrees, or even as little as 10 degrees.

Made of 3/16" and 1/4" thick aluminum , it is extremely rugged yet weighs just a little more than a pound.  You can install several of them on your pedal board without excess weight.  It has a medium form factor of just under 8" long, and it features recessed jacks to conserve space on your pedal board.  You can even run the cable out the bottom for an "underground" connection. 

PedalPusher uses an aluminum 2-stage gear train for coupling the physical footplate to the potentiometer.  This linearizes the angle-to-resistance curve for ideal smoothness and consistency.  And of course you'll never have to replace a string. 

Plug it into any expression pedal jack on the back of your audio equipment.  It has both 1/4" and 1/8" connectors, so you can choose your cable type and length.  It has a compatibility switch so you can swap tip and ring for compatibility with the broadest range of 3rd-party devices.  It also has a hidden polarity switch that swaps heel and toe.  It features a 10 kOhm linear-taper potentiometer.

Spring-to-Center Option

The spring-to-center option adds torsion springs that cause the pedal to relax back to its center position when your foot is removed.  This is useful for foot control of MIDI pitch bend, for example.  You'll need a 3rd-party product to convert the output of this pedal into a MIDI pitch bend message.  A hardware solution example would be the Doepfer Wheel Electronic circuit board.  Here's a customer-supplied video (thanks, Glenn!) that shows it in action.  A software solution might be the Bome's MIDI Translator app.  The spring-to-center option will be supported directly by future Amelia's Compass electronics products.
