Description

PDF
  • Bottom plate is slightly thicker
  • Bottom plate screws are countersunk
  • Bottom plate screw holes are the same size
  • Sleeve bushings are tighter in pedal and hinge holes
  • Top pedal plate is plain/flat, with only mounting holes
  • Top pedal plate filet replaced with a chamfer
  • Replaced slotted linkage with double linkage for linear output

Added a strain cable strain relief to replace qtpy mount, for pedals used as simple potentiometer pedals.

The sliding linkage on the potentiometer causes non-linear output, since it slides more at the beginning of travel than at the end.

I replaced this with a double linkage instead to make output more linear.
