Right I have a Boss GT8, and I have found something that is annoying the crap out of me.
I have a patch set-up that I want to have reverb assigned to the CTL pedal. The probleme is that every time I push the CTL both reverb and delay come on. I have tried to turn the delay off but this only seems to swap from "Delay off, Reverb on" to "Delay on, Reverb off".
The only solution I have found is to turn the delay setting down. But the fact the light is still there is annoying

. It's like it's mocking me

.
Before anyone asks I have read the novel of a manual, to no avail.
Any Ideas???????
