Hi. I've had my Helix less than a year so I'm still learning. I'm playing a song that requires a small boost in the chorus. I have a Snapshot called "chorus" that I'd like to be able to boost. I'd like this to be assigned to a foot switch for momentary use. So basically when I'm jamming through the chorus and the hold the boost foot switch until the riff is done, and it returns back to the chorus setting. I'm struggling. Any help is much appreciated. Thanks in Advance.
