Glitchy arpeggiating bass fuzz heaven.
Bias sets the intensity (good spot there, further to the left, about the halfway point, makes it behave more like a high pass filter)
Resonance will set how often it glitches around.
FM will also control how pronounced the glitch effect is.
Gain 3 can be turned up for more fuzz altogether. Don't touch Gain 2, I find it makes everything sound like shit.
Frequency changes the sound altogether. Adjust to taste, but a distinct possibility you take out this glitch arpeggiation with it (I left it there).
Keep the Tri/Pent switch set upwards. Downwards takes out the effect. Same with the FM switch, needs to be downward.
