I've been using my Mackie Onyx Blackjack as an electric guitar interface for a few days and it all seems to work well.
Today I noticed that even when the Input Gain knob is all the way to the left (-15dB) I can still hear the guitar. In fact the knob now has little effect until about 'midday' on the dial. I'm sure earlier today if I set the Input Gain knob is all the way to the left it effectively shut off the signal.
By the way it's not the TO MON channel which allows you to hear 'pure' input signal, that's still set to off.
What's going on?
Any help appreciated!
