I use it for 2 years on stage and rpeter, with guitars a high and low outputs. On the tuning part, say nothing, has plutt works well.

on the other hand-out "mute" GNER in noise (audible) when the tuning, which makes its use dlicate in concert. Better to remove it if possible in the chain using an AB box with output mute example.
-The pedals are sold as both true bypass, which is not quite accurate (it is fairly clear, however)
