Bass guitar Fuzz pedal. The Almighty Bass Fuzz is an original design circuit, not a variation of some other pedal. The gain is biting and thick, with enough tonal options to cover a lot of ground. Great for blending with your d.i. signal or stacking with your normal amp gain. There is a lot of volume and gain on tap, and it has a big low end. TONE Control – contours between a scooped mids EQ turned CCW, and full range with boosted upper mids turned CW. Your effect is designed to run on a 9V DC power source, negative pin (ground). This pedal is true bypass.
