Just wondering as I’m looking to use an Aux Switch with an expression pedal as well, is there an Aux Switch that you can recommend? I was looking at one online, and

I would suggest that you look at the “Documentation and Downloads” section on the H9 Web Page. You may find “Using both an Aux switch and an Expression pedal with H9” interesting.

I did look at that section, as well as go through the support forum. I was just hoping that there were other alternatives other than the Boss aux switch, and I was wondering about the issue that someone told me that by using the expression with the aux, and only getting toe/tip down position- so my understanding is that it’s either 0 or 100. 

Thank you!
