Hi Tony,
The only way to switch presets with Knife Drop is using an eternal aux switch, using MIDI, or the H90 Control app.
Normally, with our other dot9 series pedals, the right footswtich can be used to search through presets. But since Knife Drop was designed in collaboration with Third Man and Jack White, he requested the right footswitch be used to only go to his favorite preset, the first one.
