Swoll Jeorge Tripps' is a (way) huge name within pedal builder circles, his approach towards pedal designs plus his great guitar playing allows him to find the tones he desires for his own use. So when it came time for him to design a big muff style pedal he designed it to work in a number of situations which is why it's one of the more popular modern fuzzes on the market today.With 5 easy access knobs plus 2 internal trim pots, it's unusual to hear two of these set in the same way. The Scoop control is really a mid knob which has the effect of changing how present you are in a mix, scoop to sound further away and push to sound front and centre for a lead tone for example. Crunch changes the clipping type and sustain increases/decreases how much clipping there is. Compare this to other Big Muff style pedals to see just how much more Swoll this beast of a pedal really is.
