Addicted to Grunge

depends on the device

some are purely a loop for pedal to move them in and out of your signal path; others can be programmed to activate multiple loops with a single footswitch. they can also include midi switching for digital effects and control your amp channels

the Carl Martin Octa, Joyo PXL or Gigrig G2 are all ways to manage multiple pedals while avoiding the "tap dance routine" of switching lots of button on and off
