Beetronics Swarm Fuzz Harmonizer Pedal - Royal Series Analog Fuzz Guitar Effect Pedal with 9 Harmony Intervals - Reactive Modulation Controls Unique Guitar Tuner Pedal

It's like a PLL merged with a fuzz - classic setup. for a fuzz, it's pretty good, nice fuzz sounds out of the pedal without the pitch stuff, however, get a different fuzz for that tone. When you add pitch though it is so bad at tracking that you would want that going in. Want an octave down insanely huge fuzz tone? - nope. Want a nice octave-up fuzz sound? - also nope. It only does "I beat my nintendo with a sledge hammer and this is what I got" sounds, which may be what you want, not for me, though.
