Can't afford a new expression pedal after buying the TimeFactor, so I made one using an old Boss FV-50L volume pedal I had. It has a 20K dual gang pot inside. I just desoldered the pcbs from the pot and the tuner out jack, and then tucked the pcbs out of sight incase I wanted the volume pedal back. Then I just soldered new leads from the pot to the tuner out jack. It has the same sensitivity concerns as the VP Jr., but for not spending any more money, it works just fine for me.
