MacB's review (This content has been automatically translated from French)"Finally a FUZZ for soloists, which illustrates soloist here SLASH!"

MXR SF01 Slash Octave Fuzz
Distortion / Fuzz typed "modern"
Priori analog technology for rendering rather modern
9V battery connector location and 9v


Configuration can not I find easier although opinions on this pedal are in contradiction with this aspect.


Volume: Adjusts the volume of fuzz
Tone: adds more or less acute frequency
Fuzz: add more or less intensity to the effect of fuzz

Now the little specificity

Sub Octave adds low octaves octaver pedal to sound fuzz
In Octave adds octaves above the octaver pedal fuzz sound
+ The boost function: giving more juice to the octave and also the pedal assembly. In my opinion it can be used when the preamp is switched Fuzz, so the master of your amp is not the way.

It generally includes at 5 min how the pedal works.

The edition of the fuzz effect is quite simple, however we feel that this pedal up enormous possibilities, so after actually to reach some think it will take time for your look a little effect, this research will obviously be more " difficult "if you decide to add another effect of fuzz, distortion, but in my opinion it is this approach that it was also designed.

This is a fuzz solo, this is the second point that can be raised, perfect to play arpeggio, however forget the agreements, it is not done because of the rhythm.


Effect éfficace the character "modern" we are between a Zvex Fuzz Factory, Mastotron, MACHINE and supreme in FULLTONE octave, or even a FUZZ GOD RED WITCH from home, in other words illustrious pedal mentioned here, so we therefore understand in the manufacture MXR here is impeccable, the high-end without the price that goes with it. Perfect for Queens of the Stone Age, Muse possibly as Metal, Hard & Heavy to VELVET REVOLVER and other GUNS'N'ROSES.

The fuzz effect is modern, realistic without being too cold for me, there's hotter in the same kind (see HBE UFO Fuzz example but more typical year 60).

The boost function is excellent, even too much sometimes, it really should manage something if you combine it with other pedals.

Pros: robustness -
power -
good distortion/fuzz- good manufactory Look "wild" a little hard tag is excellent I like! -
This is the Fuzz guitarist in a band, rhythmic go your way! - The octaver is rather mild, less marked than on other pedals of the same type (eg fulltone ultimate octave, or visual sound angry fuzz) -
knobs interact well with each other (which gives a lot of opportunity)
Offers a wide range between the modern distortion and fuzz may also be associated with a BIG MUFF for example drool even more, do not worry, I would say it is likely that interest in it was designed.

The -: Can not be used in agreement (rhythmic), only for a solo arpeggio (an advantage for a soloist a disadvantage for a rhythm) -
The Octave can be used as separate with fuzz (it was not shocking to me, but it may bother some) -
The boost is really really powerful to use, plus it is not at all accessible on foot, this is a failure for me to pedal design, it is accessible only by hand, it will be necessary you fall in concert or repeated to enable or disable it, see possibly play on your guitar knob-
Versatile little, only for good rock or heavy rock that sends post, hard & heavy, metal. It is not made for blues, classic rock, or even to take to HENDRIX and then look at the more modern sound.


I do not use it, but I spent over an hour in the store, plugged into a mesaboogie lonestar special on channel "tweed" Fender typed, and my trusty Fender Telecaster with TV Jones Classic pickups to try . I have not done for two reasons: first, I am rhythm (not solo), the second I wanted something more organic, warmer, fuzz before this (the time before), I FUSE BLOWER tried the French Jacques mercer its brand JACQUES STOMPBOX I much preferred, corresponding more to my needs at the time, covering a broader "sound spectrum" Fuzz that one.

My rating is between 7/8, this is a very good pedal overall, but it is essential to try before you buy it if you want. On the other individuals specifically for this model, the advice I give here may be called in question completely, so try I repeat.

MXR SF01 Slash Octave Fuzz
It is a dual Octave (octave below and / or above the octave) coupled to a fuzz. Both effects are not totally independent, and must spend a little time with the machine to understand what we can do with it.
This is a 100% analog pedal that works with 9V battery or Boss style power.


It's not the easiest pedal to use in the world, but with two in common sense, it comes out very quickly.
It is controlled via two footswitches and a mini switch called "sub into fuzz" (only activated by hand). To this is added 5 rotary knobs (volume, tone, fuzz, sub octave and octave up).
The footswitch activates the left octave below, and there are two possibilities:
- If the mini switch "into sub fuzz" is disabled, you get only the octave below in addition to our basic sound. In this case the knob "volume" manages our level of its base and knob "sub octave" of the octave below.
- If the mini switch "into sub fuzz" is engaged, a fuzz is applied to our basic sound AND an octave below. In this case the volume knob manages the overall output level of the knob "fuzz" the rate of gain of the fuzz, and the knob "sub octave" still manages the volume of the octave below.
That said, we can only get more sounds with the first switch:
- The basic sound + octave below, all without fuzz.
- The basic sound + octave below, all with the fuzz.
- The basic sound and fuzz without the octave below (with the knob "sub octave" 0).
- The octave below without fuzz and without sound basis (volume knob to 0), short bass sound anything!

Finally, if you activate the right footswitch, the octave above appears, coupled with a fuzz.
Two remarks:
- You can not get the top octave fuzz WITHOUT associated with it.
- You can not get this octave above ONLY if the switch itself is left enabled.
That said, playing with volume settings, you can make disappear the sound one octave below, which keeps only the fundamental tone and the octave above.

Writing is not easy to be understood, but the pedal under the eyes, while it quickly becomes very logical. He said it would have been possible to make more intuitive, hence the 7/10.


Firstly, this is not a otaver polyphonic style POG, so we forget the open chords and organ sounds.
This is a pedal Riffer or soloist. In this area, if you search sounds thick and distorted soundscapes and loaded, it is huge, and sound capabilities are very broad, if indeed that is a bit patient to understand its operation.
The sound quality is there, the fuzz reminiscent of the famous "FUZZFACE" from Dunlop and the different sounds are very successful (if you plug it into a good tube amp of course).
Followers of stoner, metal, rock, hairy and / or industrial, it should please you!


I use it for 15 days and I have not toured the wide possibilities that sound pretty box can offer, but I am amazed rendering!
This is a very particular, which in my opinion has nothing to do with Slash, but it is the rigor cares.
I think this is very successful, and it completely meets my expectations. The only downside might therefore be a grip a little chaotic at first, not a fuss.

MXR SF01 Slash Octave Fuzz
+ Octaver fuzz MXR signed by Slash
1 button for the volume into sub fuzz only works when the switch "into sub fuzz" is enabled, otherwise it is the mix of sub octave when the switch "fuzz up" is switched on and when nothing is activated it is a little Volume to 0 because the octaver was further volume ...
One tone knob for the sub into fuzz
1 button for the intensity of the fuzz into sub fuzz
One sub octave button for the volume of sub octave when the switch "fuzz up" is enabled
One octave up button for volume up when the octave switch "fuzz up" is enabled
1 switch on / off activation effect
1 button on / off "sub into fuzz"
1 switch on / off fuzz up
2 trimpot inside Gain and Tone except to unscrew the pedal requires a special key
Pedal True Bypass


Above all it is an octaver, it's either one or the Octave Fuzz octaver with, but Fuzz is not all alone
If this is the first time I read the instructions a pedal ... : S the interact button, after activation of the switch up fuzz, fuzz into the sub or two, the possibilities are endless let's say it's a bit of a pain in testicle beginning to find his ...


The octaver in itself is a kind Boss OC2 octaver and more ... the octaver is not polyphonic, you can flatten the agreement but it is ugly must play a note by note, if there is no problem of tracking the OC2 as it does not answer, the its the octaver is pretty cool, on the other hand careful to put it behind the compressor and not before, the dynamics are not going to be the same, if I amused myself with the couple Red Fuzz Benrod I don ' 'm not happened the mix of the two (octave fuzz + other) is not at all possible it's a shame ... so you have used the Fuzz integrated so either Up or Sub or both, depending on the desired effect you can spend some time in the settings, but so overall the result is not bad but there is a little side not very natural in the Fuzz ... I prefer with the fuzz up the sub into the mix of the two fuzz is not too great is returned in


It's not bad, but must have utility if it will remained inactive for a while, those like me looking for a way to play it octaver and Hendrix Octavio is rather the light that one can try but store it may be difficult to test given the setting and the potential of the beast that is just 15 min ...
Basically I wanted to Roger Mayer "mink octavia" button with his tone more, but since it is virtually impossible to find I folded the SF01, starting price of € 155, for the moment I still have mixed feelings about the possibilities and sound quality offered that I find a little deca a Roger Mayer Octavia ...
