Yes I have and while it does sound wicked I find you have to tune the amp to the pedal, not the other way around. It may just be that the KSR is tight enough on its own that it just needs a tiny push instead of a big one, but I find I have to dial my KSR to sound flubby to make it good and at that point it’s unuseable with the boost off.
But in the words of the dude “that’s just like, my opinion man”
