OVERVIEW

Time-tested tone in a more compact package.

Guitarists of all styles, from Hendrix devotees to garage rockers and stoner-metal fanatics, will dig the familiar late-Sixties/early-Seventies crunch delivered by the MXR M-173 Classic 108 Fuzz. Dunlop has taken the guts of the BC-108 loaded Fuzz Face, placed them in a more pedal board-friendly shape, and added the modern conveniences of a battery door, optional AC operation, and true bypass with LED. The M-173 pedal's Buffer switch eliminates the audible oscillation caused when some wah-wahs are placed in front of a Fuzz Face. The Classic 108 Fuzz Pedal comes in a heavy-duty Phase 100-sized box with a sweet hammer-tone turquoise finish.

FEATURES
  • Pedalboard friendly
  • Optional AC operation
  • True bypass

This fuzzbox is about as good as it gets when it comes time to fuzz things up and get real dirty. Think Fun House, Band of Gypsies, Inner Mounting Flame, Vincebus Eruptum, Maggot Brain, You're Living All Over Me, hell, even Superfuzz Bigmuff, ironic as that may be...I can and do get all of those sounds. And you can to! It's just up to whether or not you can paint your own sonic picture, create your own fuzzy lysergic-drenched architecture. Follow in the footsteps of all of the great fuzz pioneers and you will Feel Alright*. "Can You Get to That?"



*Feeling Alright can be increased if wah-wah pedal is also implemented. WARNING: FUZZ MUST BE PLACED BEFORE WAH EFFECT.



Besides the notable exception of the buffer switch and battery compartment (thank god for that one), this pedal doesn't have a whole lotta added on crap. Which in my opinion is good; whenever I feel the urge to clutter up my signal path with new toys, I feel it's better that things stay simple. It does what it does, and I love it for that.
You honestly can't go wrong with MXR's quality, I used to own (until unforeseen circumstances appeared) a Dyna Comp, Stereo Chorus, Wylde Overdrive, and a Distortion +; all of which held up for a good long while: the dyna comp only needed fixin when some ninkanpoop spilled beer on it Halloween night, the wylde overdrive got a busted up by a paint job that a friend took upon himself to undergo which seeped into the electronics, the Distortion + shorted out after it was on the roof of my friends car (it stayed up there the entire trip, 40 miles...then came the rain...) and the stereo chorus has been with me for 5 years, no complaints (other than sounding like 1983). After straightening out my general carelessness concerning gear, and coming to the realization that nothing sounds better than an undiluted signal path (blame Hubert Sumlin, R.I.P.), the Classic Fuzz will be guarded with the upmost attention to not only it's general safety, but also concerning it's musical implementation...which more and more is finding it's way into more songs, more shows, and more recording sessions I play on. I've had it nearly a year now and it still has the same battery I put in upon taking it outta the box. Now, I've heard complaints about the battery door being flimsy and ill-constructed, but I have to admit that I've had no problems with it so far. Just treat it like a tool, physically and creatively speaking, and you will be rewarded with a sturdy tone and a sturdy fuzzbox.
It is a bit pricey, but hey: if you want quality, than you gotta bust out the old wallet and shell out a few bucks. Why bother spending 50 bucks on a pedal if it's going to be A) made with inferior parts or B) sound inferior. This pedal is worth every dime, although if you can't afford it I'd highly recommend getting...just save up for the damned thing. You won't regret it.

I would play this one (and all fuzzes)first at your local shop or borrow a friends prior to buying it and not go solely off- You Tube/internet demos and 5-star reviews. Some pedals you can buy sight unseen but fuzzes are a different story for me.Case/hardware - The first thing out of the box you will notice is the weight of this pedal, it is really a heavy case (not much inside of course) but the stomp switch seems to be of lower quality than other pedals I have and has a loose feel to it. The second thing I noticed is that the battery door is the type that protrudes out past the bottom of the case and hangs past the rubber feet....meaning if you set this on a tile floor / stage = it will spin around like a bottle. This could make securing it with velcro to the pedal board a problem ( I know the idea behind this design but, I would rather have to remove screws to access the battery than this door.) Last thing about the case is...the IN/Out jacks are on the top which may not make a difference to you but was an issue with mounting it on my board with all other pedals before and after being side jacks.The sound - kind of disappointing to me that I plugged it in and turned it on and it was just like a boost pedal for most of the dial not even an overdrive let alone a fuzz...I kept turning and turning the fuzz dial and could not get it to break over into fuzz territory till like the 3:00 position then all of the sudden? I had my strat ( with texas specials) on 9 and almost always have to have it on either 9-10 to hear it actually "break over" to fuzz. Bottom line I had to really a play with all volumes amp,pedal,guitar back and forth in my set up to get an actual "fuzz" not boost/OD/distortion tone with most of the fuzz dial not offering much but a boost. When it finally does near the end of its dial range = it sounds great (fuzzy and not too dark) but I will really have to fiddle with this pedal alot...not like the Big Muff Pi that has just gobs of fuzz even on low settings with any amp solid state or tube.The MXR Fuzz has a buffer switch kicks in highs and mids when engaged but made it less "fuzzy" but brighter. To me this pedal seems to need help prior to it like maybe an OD pedal which I will try next ( a Fulldrive2). The MXR fuzz does play nice with both an Area 51 wah and/or Fulltone Clyde deluxe after it. The buffer really did not factor in with the wahs I tested with it. I'm not saying do not buy it just try it first - then buy it if you like. Fuzzes seem to be touchy with what is before and after them too and this one is no different- Good luck

    I liked this pedal very much. I would have kept it except for the ridiculous "remorse fee" that I was going to be charged for the return of another fuzz unit that I bought in conjunction with this one. Because of that charge alone, I returned them both.
    Musicians friend please review your policy or don't offer free shipping if you cannot afford to lose profits when items are returned.

    Fuzz - topia

    By Stephen-Taxv1

    from Saratoga Springs, NY

    Comments about MXR M-173 Classic 108 Fuzz Guitar Effects Pedal:

    I have to admit, I?m a fuzz pedal junkie. I own the DOD Flashback Fuzz, the BBE Free Fuzz, and a Little Big Muff. When recording, I?ll often switch fuzz pedals for different segments of the same lead or guitar melody. I just received the MXR M - 173 and it is the best of the lot. It completely nails the classic fuzz tones of Pink Floyd, Hendrix, et al. The pedal goes from smooth melodic fuzz to all out star spangled craziness. As advertised, the buffer works well to cancel oscillation when the pedal is preceded by a wah. The buffer also clarifies (less muddy) low gain / fuzz settings.MXR has done a great job in making available classic tones with modern conveniences at an extremely reasonable price. I love this pedal!

    Great Classic Fuzz

    By Dave From Ohio

    from Cleveland

    See all my reviews

    Comments about MXR M-173 Classic 108 Fuzz Guitar Effects Pedal:

    MXR has issued a fuzz pedal that gives some really great, classic rock fuzz at a very reasonable price. You can get all the Fuzz Face sounds, and with some amp tweaking, you can get some of the more biting, germanium-type sounds as well. The buffer switch helps when running a wah in front of the fuzz, but also acts as a tone switch as well, adding a nice amount of treble to the pedal's tone. Very useful with Les Pauls, but also gives you more tone choices too. This pedal really sounds good with a nice tube amp, especially if the amp is running pretty hot to begin with. I have tried/owned many of the boutique fuzz pedals out there, some were good-most were overpriced and overhyped, but this MXR pedal is the best deal when looking at sound and quality at a reasonable price. MXR is really making some great pedals these days !

        I picked this pedal up in as a restock on Musician's Friend the other day, and I just received it. I couldn't believe the sound quality I got with this! The buffer switch is a really nice touch and really cleans up the signal a lot. You get that great late 60s/early 70s sound in a great feeling way. The responsiveness of the pedal, even at low settings is fantastic! The quality of the overall housing is nice and solid, too.

            In my opinion, even with the mini fuzz face out, this pedal still has a place on people's pedalboards. The buffer in particular gives this pedal a truly unique tone and an added level of usability that the mini fuzz face just doesn't offer, for the same price. This is truly an underrated pedal.

              I have been playing for many year and in the beginning I was all about the distortion pedals. As I grew more refined (older) I found overdrives to be my flavor of choice. I had never owned a fuzz pedal mainly because the guys I was around that had one sounded too harsh, like a swarm of bees. But I gave this a try and all I can say is I am sold.
