I've got a stand alone volume and stand alone wah on the right.
Dunlop expression in the left.
Would normally be a subtle wah or pitch.
As its a wet weekend here in England I might do some tweaking later 😉
I generally use the button for morphing rather than a pedal. I havent got much kemper time in for the last 6 months and I have spotting some interesting delays and reverb that are prob worth experimenting with pedal morph.
I've always felt that the kemper users and groups etc are 95% amp and cab orientated, which I guess should be expected.
But is always interesting to find great rigs which are based around effects.
Theres some really interesting stuff around
