The Bass Fuzz Deluxe is MXR's latest creation in their award Bass Innovations series . MXR has dug up a rare vintage fuzz and modified it for the modern bassist. The resulting stompbox delivers a cutting and bold fuzz tone without degrading the punch and clarity of your original signal.

Real good fuzz pedal


I use this Fuzz both as a fuzz and a distorted boost. It's better than a lot of other fuzz pedals, because you don't lose the bottom end. It's very transparent. It has great tone shaping options. My only complaint is the hum. Even powering it with a Voodoo Lab power supply doesn't eliminate the hum. It's not a big deal unless you have quiet parts to the song.

Sam Ash was only one that had pedal in stock. ...needed ASAP for a gig. Great price and incentives. Item came on time ready to go! Thanks to customer service for setting up my account and applying coupon. See you again






I have this pedal for a while now and it has become one of my favorites , I really love the fact that you don't loose any bottom end the DRY & BLEND knobs are great features, is all analog, very durable , sure there's more choices out there but hey this was my and im very happy with it CHEERS!!!

Sounds Great


Awesome sounding fuzz. I tried this in-store next to a couple other pedals and it adds fuzz without losing the low end of your bass tone. The wet/dry blend knobs are great too. The only downside is that the "on" LED is blinding (like all MXR pedals) and it focuses all the light pretty much straight up. I used a nail-file to scratch the lens on the LED to diffuse the light and it's still brighter than my other pedals, but now it's at least bearable to look at.

One COOL Fuzz Box! MXR-M84


Gigging Bass Player, one of my most used pedals . Best Fuzz pedal since the 60's. Old school Fuzz, excellent control on tone you can go from mild to wild without losing your bottom line. Not very noisy even when cranked.I tweek my EQ on the high end to keep everything smooth,big bottom end without getting muddy.This is one COOL FUZZ.
