I have access to a Guitar Effects Pedal G2 by Zoom (https://www.zoom-na.com/sites/default/files/products/downloads/pdfs/G2.pdf) and I've been perusing the manual for a distortion-free volume amplification (and reset) via one of the buttons. I want to press the button to increase volume for a solo then press again to return to the previous volume.
I'm either missing something very obvious or the G2 is too advanced for such a simple operation. I know I could just buy a volume pedal but I'm trying to make do with what I have.
