Take a snarling dog and the rev of a Ford GT, added to distortion, you'll be somewhere near this sound.

I feel sorry for anyone who hasn't tried this pedal. As for me, it is now a must now that I have heard it. The price listed for it, I'll call it generous because even if it was $500, it'd still be worth the money. Whether you're looking to wail on Hendrix solos or just experiment with new sounds, this is the very under-rated candidate to accomplish those needs.

To octave, or not to octave

Fulltone Ultimate Octave was my first fuzz pedal purchase. Greg helped a LOT AS ALWAYS! He allowed me to demo an MXR classic fuzz, a Hendrix fuzz (the funny wedge shaped one), and the Fulltone Octafuzz (reportedly the exact same circuit as a Tycho Brahe Octavia). These were all great, but none of them were excellent. I was set on leaving with a fuzz, so I browsed on the sweetwater website one more time and found the Ultimate Octave. With or without the octave effect, this pedal is completely usable, the tone knob is great, great as in, there isn't really a "dead zone" in the sweep. It is a pretty loud pedal (the volume on mine never goes further than 10 o'clock). The fuzz knob for my personal taste gets a little too hairy past 2-3 o'clock. The only thing not excellent about this pedal is the "fat/bright" switch. I leave it on fat all the time because the bright is just way too bright without any mids, but its ok, because if I need that sort of flexability, I know I have it at the flick of a switch. Excellent pedal with a very dedicated fan base, as I discovered after I bought it.
