Zipper noise with Wah and

CorOS Version: 1.0.1

When using a Source Audio SA161 Dual Expression Pedal to control a Wah block I get what sounds like zipper noise when approaching the toe down position (treble end of Wah). This happens when using either Expression input 1 or 2, and it’s with both the Bad Horse and Bubba Wah models. The Bass Wah works correctly with no noise or issue. I tried different cables too, and it wasn’t a cable issue.
