Description
The MXR M173 Classic 108 Fuzz Pedal is a homage to the late 60s and early 70s iconic fuzz sound that guitarists of every genre can appreciate. From Hendrix's fanatics to stoner-metal enthusiasts, this pedal delivers that quintessential crunch sought after by so many.
Based on the revered BC-108 loaded Fuzz Face, the MXR M173 Classic 108 Fuzz Pedal offers the same legendary tones but in a compact, pedalboard-friendly unit. It's not just the vintage aesthetic that's been maintained - the original guts of the circuit have been preserved, ensuring an authentic, rich fuzz tone.
But this isn't just a nostalgia trip. This pedal comes with some serious modern upgrades. The addition of a buffer switch solves the common problem of audible oscillation when a wah-wah is used in conjunction with a fuzz pedal. And for the road warriors out there, you'll appreciate the sturdy, heavy-duty Phase 100-sized box and the convenience of an optional AC operation along with a battery door.
Key Features:
- BC-108 circuit for authentic vintage fuzz tone
- Buffer switch to eliminate audible oscillation with wah-wah pedals
- Convenient battery door for easy power source changes
- Optional AC operation for versatility
- True bypass for preserving your tone
- LED on/off display for clear visibility
- Housed in a heavy-duty metal enclosure for durability
- Hammer-tone turquoise finish for a stylish look

Absolutely fantastic Fuzz Face
As a gainy silicon fuzz face it as all the edge and grind but most importantly it gets not lost in the mix due to a proper midrange boost. The internal buffer gives it not only all the flexibility you need to place it anywhere in the signal chain but also changes the tone, the build quality is as good as a pedal can be. Does not need to hide behind much more expensive fuzzes in any way!
Some people in certain forums think this is a good entry into the world of fuzzes. My opinion is rather that the MXR Classic 108 is to be regarded as a Tubescreamer, a stable standard in the big world of fuzzes. You can go on and on searching for so called boutique fuzzes, but you can also just stomp on a used MXR Classic 108 and start writing a song. And I'm pretty sure it's going to be pretty good song.
Preferred Settings + Usage:
Fuzz slightly behind max, volume anywhere above 1 o'clock, buffer to taste.

Kick ass fuzz.
This sucker is basically the Original Dunlop Blue Fuzz Face but compacted from the original size. It's still a little big compared to the average rectangular pedal but it doesn't eat up too much pedalboard space. I previously owned the Dunlop Fuzzface and while I did like the classic tone, its configuration was a little inconvenient. The in/output jacks were switched to the non traditional sides of the pedal and it only worked on a 9V battery so you couldn't charge it. This MXR pedal fixes both of those problems while keeping the sought after tone consistent. The sustain on the 108 Fuzz is incredible. I like to play with the buffer on since it compresses the tone, which I like. Its sound can come across as either a medium/fat overdrive or it can turn all the way into a Jimi Hendrix spacey fuzz experience. I think it's a great fuzz and was able to emulate John Frusciante and Gary Clark sounds quite easily. Check out some Youtube videos to hear the sound I'm trying to describe. Definitely worth getting. I hope this helps!
fuzz forever.
when i was 12 when my dad and i went to the local record shop and he bought me jimi hendrix electric lady land, i have been obsessed with fuzz tone, and rock/blues. but for me when it comes too fuzz tone, i have a bit ocd so the fuzz has to be just perfect or ill hate it.
this guitar pedal is perfect.

it gets the silicon fuzz face sound you're obviously chasing
Proper fuzz
I especially like it for the buffer button, as fuzz pedals react very differently to power supplies and other pedals in the chain.

Classy but...
It has an awesome sound but it compresses like a maniac. The over compression is especially bad for chords.

she's basically a tweaked up blue fuzz face like Hendrix used at Woodstock, can't go wrong
