Block Diagram Error

I just spent an hour trying to diagnose why no sound was coming out of my Tube Amp Expander. As it turns out, it was a hardware problem: A defect in the processing unit that controls the notes played on the guitar caused the volume pedal to be rolled all the way back. It’s a glitchy system that is prone to ill-timed &$#%-ups. But in trying to diagnose the issue, I discovered that while my TAE is working just fine, there is actually an error in the block diagram printed on the top of the TAE and in the user manual.There are two volume control inputs on the GA-FC foot controller, “Pre-Effect” and “Main”. I use the Pre-Effect input which comes earlier in the signal path. The block diagram shows the Input Sig/Peak light coming before both volume control inputs in the signal path. If that were true, then the Input Sig/Peak light should have been lighting up when I played, even with the volume pedal rolled back. But it didn’t. And that threw me off when I was trying to sort out the prob…
