hello
I am thinking of putting 2 a/b's in one box with output B of them going to the same output.
Unsure if this can be done with out massive hum.
Background: I play bass and guitar in a band using a doubleneck. I want to have an a/b for each neck to send the signal to a common output tuner (tu2). This will also act as a kill switch for each.
I modified an a/b to show what I am thinking.

There is individual outputs for the doubleneck and there is a neck selector so only one signal will be going to the tuner at a time. This way I can be playing bass and then mute it for tuning. No need to have two tuners.
I would be looking at using bi-color leds and power socket not battery.
Please let me know what you think.
Thanks, Steve
