Fulltone Ultimate Octave
The fulltone ultimate octave is fuzz pedal with a foot switchable upper octave effect.

The pedal has controls for volume, tone, and fuzz as well as a fat/bright switch.
The "fat" setting has more mid range while the "bright" setting is scooped out with tons of bass and treble. It can be run from a 9 volt power supply by using the rear DC jack or from a battery.

There are two stomp switches one being the true bypass and the other is for the upper octave.


Setting this pedal up is simple as everything is clearly labeled. You plug your cables in then put some power to it and kick it on. The manual explains everything well and gives some tips on how to make the most of the octave effect.


I used this pedal in a guitar set-up mostly into a fender champ and a Framus tube amp. The pedal is true bypass so it does not change your tone when off. I bought this pedal looking for a mean sounding fuzz with an upper octave but it fell a little flat on my ears. It was not bad but also was not anything special. The fuzz was rather tame for my liking and was very picky about the amps it was being run into. I could not get it to sound good into a clean amp and had trouble getting good sounds when run into my main amp's light crunch channel. Running it into a tube amp with a slight break up yielded the best results. Another annoyance was any time I got a good sound then tried it with my band it would not cut through the mix. Then I would adjust the tone knob but when I got to a point that it could be heard it sounded brittle. The octave effect was also not very prominent and I wish there was some sort of dial to control the intensity of it. It should also be known that hitting the octave switch makes the sound drop for a brief moment before coming back in with the octave effect. I think this is the same with all analog upper octave pedals.

I do not want to completely bash this pedal because there were some times where I could get a great sound out of it. Mostly in a recording environment where things can be further processed. It also sounded pretty good into older amps on the verge of break up.


I think at the 200$ range there are better options out there.I also had problems with the switches on my pedal and was not greeted with the best customer service.
There are many people who love fulltone pedals but for me it just was not too inspiring to play.

Fulltone Ultimate Octave
The Fulltone Ultimate Octave is a stomp box designed for use with electric guitar.  It can be used with any electronic instrument, but I've only used it with guitar.  The pedal is standard as far as its characteristics go, since it has a 1/4" inch, output, and a nine volt power supply jack.  This isn't rack mountable as it is a foot pedal.


The make up of the Fulltone Ultimate Octave is fairly simple, and at the same time there is a lot to work with here.  The pedal has parameters for volume, tone, and fuzz, along with a switch to select either a bright/fat mode.  It has two foot switches - one for bypass (on/off) and one for octave up.  You don't need to know all too much about overdrive or octave pedals, but it will help to have a little bit of prior experience.  I've never had a need to look at the manual for the Ultimate Octave pedal, and don't think that one is really necessary.


The sounds that are possible with the Fulltone Ultimate Octave are pretty unique to all get within one box.  The octave features are limited, as I would really consider this more of an overdrive/fuzz pedal with an octave up feature, so the name is a bit misleading.  I have used the pedal for a few recording sessions with a Gibson SG and a '65 Fender Deluxe Reverb, as I felt the SG was a good choice to work in tandem with this pedal.  I do wish that this pedal with a bit more transparent sounding with its overdrive, but will do the job for times when you are looking for more thickness rather than transparency. 


Being that the Fulltone Ultimate Octave is a pretty unique pedal, I wouldn't recommend it as your first or only overdrive/fuzz pedal.  Rather, it is the kind of pedal to use in tandem with more traditional overdrives and distortions to lend support.  However, every player is different so while I look at in this way, I wouldn't be surprised to find someone else who uses this as their go to distortion pedal.  The price isn't the cheapest, but Fulltone puts a lot of care into their pedals, so you're paying for this upper end quality, which is worth it in my opinion if you're interested in this pedal...

Fulltone Ultimate Octave
The Fulltone Ultimate Octave is really two effects in one pedal. It's a silicone-based fuzz pedal and a octave-fuzz pedal. You can turn the octave effect on and off when the fuzz is on, but when the octave effect is on it changes the fuzz tone pretty significantly, so it's probably best to think of them as two separate effects, except that you can't have the octave effect on when the fuzz is not.

There are three knobs (volume, tone, fuzz), a toggle switch (fat/bright - it cuts or boosts the mid range), and two foot switches (on/off and octave up).

Unlike some fuzz pedals there is a jack for a 9v adapter which I believe accepts the normal Boss-style power thing.


This pedal is pretty straight-forward. Everything does what you'd expect it to do.


Let me say first that every sound you can make with the toggle switch on "Bright" is useless. This setting gives you a scooped mid-range, and while this would seem to be useful for certain kinds of music, particularly metal (which, I should be clear, is not my thing), I can't see even metal heads finding the sound of this pedal on "Bright" to be good for much. It just sounds tinny and yucky.

With the toggle switch on "Fat" you get two usable effects. The fuzz alone is a nice silicone transistor sound. Pretty abrasive sounding, and no, it does not clean up much at all, but this kind of buzzy distortion certainly has its honored place at the table. With the octave up feature on you get a very nice, though by no means polite, octa-fuzz type sound. Extremely biting, great for cutting through the mix, and with, at the same time, a lot of body behind it (as long as the toggle switch stays on "Fat").

As with most octave-fuzz pedals, chords sound pretty much like a car crash, and fourths give off that weird ring-modulated sound that makes every day seem like halloween. But playing lead riffs, particularly up around the twelfth fret, gives you the searing '60s sound that you want.


It's strange, I like this pedal a lot, but I almost never use it. I feel like the only time I'd want to present my own songs with this guitar sound would be if I a) wanted to scare the crap out of people, or b) wanted them to make direct comparisons between me and Jimi Hendrix. I'm not really attracted to either of those possibilities.

Still, it's a lot of fun to play with at home. Probably the best pedal of the octave-fuzz genre I've used. And like all Fulltone stuff it's built to last.

Fulltone Ultimate Octave
It's a fuzz pedals of two modes and Bright Fat (fat = booster) and with the octave suprieure dubbing.


Super simple;
- 3 potentiomtres: Volume (attention: she pushes away !!!), super Tone, Fuzz
- 1 slcteur: Fat (treble boost), Bright (Bass Boost)
- 2 switches: on / off and Octave Up / Off with LED red and yellow LED.
- 2 between In and Out
- Possibility to set 9V battery or battery
- No Manual, as unnecessary
- Casing super stiff
- 2 year warranty by the store
- 5 year warranty by Fulltone


Excellent quality (among other uses by Steve Vai and Joe Satriani) in clear sound in his fuzzy, the octave double the volume of the pedals, it takes a dj max ...

The two switches are invisible, the pedals do not sound at all (just a little bit if everything is back ...)


The PDAL is a good compromise between Axis Fuzz, and a Octafuzz octavia. For a mere $ 240 instead of buying all these dernires ... More and clean sound with a Start, you will be confused with some legends ...
