OK, that's what I suspected. You're probably wondering: Why do that…just hit the preset switches on the PF. Answer: I have the PF set up in an effect chain in the back line (not at playing position on stage). It would be nice to use a simple and small foot switch to toggle between presets. This would take up less pedal board real estate than the PF itself. So I'll throw this in the suggestion box: an AUX SW destination that toggles presets. Thanks.
