I know this is a long shot, but does anyone have any idea what fuzz pedal she is using? I have watched a few of their videos and looked through a bunch of pictures. Looks like she has a Boss TU-2 going into a very large orange and black pedal (I have no idea what this is).
It's hard to tell just from audio exactly which fuzz is in use. Even if I had that good an ear and that much experience with pedals, each one is adjustable to a lot of different tones and what amp, bass, and other pedals are in use will all affect it. Orange and black - might it be a Malekko B:Assblaster?
