Since the technology is there, consider adding Siri (or Alexa) to your guitar pedals. Say that your hands are full because you are holding your platinum album in one hand, and a beer in the other, and for whatever reason, you need to adjust the pedal's parameter because a fan hollers at you to play Freebird. Simply say, "Hold my beer." "Siri, turn up the gain 10%." Bam, you're done.
