The Prophet '08 PE Module Conversion Kit from Dave Smith Instruments is an upgrade from the standard Prophet '08 to the PE Prophet '08 Potentiometer Edition. This kit is a direct replacement card for the standard panel board. This board features analog potentiometers to replace most of the rotary encoders of the standard Prophet '08. The main board may need a minor modification, but anyone with basic soldering skills should be able to do it.
This kit does not include replacement knobs, but a Prophet Keyboard-style knob kit is available separately.
