The Amp Out signals can be muted individually, but the FX loop is still in the signal chain. Regardless if turning down the send control, the FX loop sends a live signal out. Bug?
Allow the send control to fully mute the signal when turning down the control.
Why is this important? If a user is set up using the FX loop in the '4-wire' setup and using the other Amp Out signal for a separate destination and guitar set-up (separate amp, etc.), the user needs the 11R to be able to mute the FX send completely so that signal (which will be connected with the first guitar set-up) is completely bypassed.
