I should take a picture, but not currently by my Kemper.
I have the remote and for one of the effects slots, Switch "II" I have Pure Boost selected. So top left is red in colour for the effect. Turning it on and off makes the bottom left led go from off to white....as expected. But the bottom right led is permanently white.
I think it's to do with another effect that it can be programmed for it to control, but I can't work out what it's related to.
How do I find out?
I am currently reading the manual!
Thanks
Andy
