Cable checker

Use it as a cable checker I/O. Turning down the volume so that lovely crackling noise don’t get you everybody’s gritty attention, and checking the screen to see that the signal output reacts :boom:.
Minding also the guitar tech here (who should be the absolute only other person getting near your QC. Especially don’t let the smacked xylophone player near it :sweat_smile:).
No use for another very handy gadget.
