MXR M84 Bass Fuzz Deluxe
Analog fuzz pedal compact size, true bypass, 9 volt power supply.


Configuration very simple tone knob for the tone of the effect, one knob to mix the light signal and the effect, one wet knob to the output level of the fuzz and fuzz knob to the grain of the fuzz. Very clear but useless manual, simply rely on his ears.


We are in the presence of a "creamy" fuzz with a tight grain. Some find synthetic, but on this particular effect I do not understand the concept because it is the principle of fuzz and I prefer to speak of a more or less grain serré.La dynamics are excellent and dry knob plays very well its role to "melt" bass in effect or otherwise preserve low and inject effect. Fuzz tone knobs and enable a broad range of sounds to go soft fuzz to more aggressive fuzz.


I recently and frankly I love it! Nothing to do with the bass big muff and muddy and unclear sound (and unbearable lag time!). I had a great Mazzette (which took place very well in the mix with a very defined sound) however the sound I was looking for was less aggressive, more creamy. I found with the mxr. I think she will not leave my pedalboard before long! Excellent value for money. I advise you.

MXR M84 Bass Fuzz Deluxe
Speak little, speak well: we are dealing here with a great fuzz pedal that I see are qualities. Here, it is said.

Analog ... OK. True bypass ... OK. Manufacturing ... OK. It's tough, you feel immediately that will last for years without flinching. 9V power supply, can put a battery by unscrewing the base. In short, the classic MXR and holds the road, I'm not disappointed. Oh, and I love the color.


The M84 stands out with its 4 knobs: Dry, Wet, Tone and Fuzz. The Dry adjusts the volume of incoming sound of your bass, while he manages the Wet volume fuzz pedal (a good point, one senses immediately that this will greatly facilitate the settings, I find it much more obvious here as other pedals). Tone then allows you to choose the color of your sound, a good good dark fuzz to sound more clear and sharp. Finally, the knob of Fuzz manages to highlight the strength of your fuzz, who can be discreet or yuck. Note that the tone only affects the Fuzz knob.

And for me it happens to one of the great strengths of this pedal: for each knob settings are fine (1 mm or 2 and hop on the mean difference) and thus allow a wide variety. It is clear, clear, effective.

The manual provided is very basic, a little leaflet in three parts with the effects of knobs, three presets and a pretty useless picture. Note also the presence of a small MXR catalog that makes you want to slam all his money.


In terms of sound that is also very very good. I do a lot of research and tested several pedals but without ever having to crush up the M84! I love its texture, its heat and its ability to keep some nice bass. I preferred to the Big Muff Pi (not sure, lack of character for my taste) and MXR El Grande (which I love, but I find less convincing settings). I tested in both passive and active, and it is equally effective on both sides. In short, I like. I have not tested with a guitar, but I think it may be worth it :)


It's only been two weeks since I played with but I sure not to fall for another fuzz before a long time! Certainly the price is higher than a Muff, but also much lower than that of a Wooly Mammoth. So for me it keeps a very good price / quality ratio of its grain, its cool knobs Dry / Wet, its fine quality settings and a fab copy. I highly recommend the test if you cross a ;)
