Master fuzz, turn the bias setting down pretty low, it will get that kind of splatty/velcro tone
Play with your volume pot on your guitar,vary your pick attack too, fuzz tones are very dynamic in that regard
Its tough to get a perfect fuzz tone on the Axe, because a fuzz circuit is so dynamic and depends so much upon pickups, volume, tone, attack, even temperature on same transistors, but the Axe can get pretty close. Even to do the job
There are some fairly inexpensive hardware fuzz pedal options on the market too, like the EHX Satisfaction fuzz, which was designed to mimic that tone, probably find one for like $50 used
