Give Your Bass the Fuzz it Needs!

From Dunlop's MXR Bass Innovations line comes the MXR M84 Bass Fuzz Deluxe pedal. The MXR M84 Bass Fuzz Deluxe gives you a cutting and bold bass fuzz tone that's ideal for modern playing styles. It's based on a vintage fuzz pedal that's been modified for the bass frequency range and tweaked to perfection. In addition to saturation and tone controls, you also get separate wet and dry level controls, so you can go from dry with a touch of crunch to nothing but fuzz with the MXR M84 Bass Fuzz Deluxe pedal.

MXR M84 Bass Fuzz Deluxe Pedal at a Glance:
  • Wet and dry controls let you mix your tone to taste
  • Designed to preserve the fundamental tone of your bass
  • Unique distortion circuitry based on a modified fuzz pedal
Wet and dry controls let you mix your tone to taste

One of the most important things that sets the MXR M84 Bass Fuzz Deluxe apart from typical bass fuzz pedals is its independent wet and dry volume controls. Instead of merely blending the affected and unaffected sounds together, these controls let you create the illusion that you're running your bass through two separate amplifiers. The M84 Bass Fuzz Deluxe makes it easy to preserve the dynamic punch of your dry bass sound while adding in the perfect amount of grit - all the while driving your amp as hard as you want to.

Designed to preserve the fundamental tone of your bass

Anther very important thing about the M84 Bass Fuzz Deluxe (and MXR's bass pedals in general) is the way it manages to preserve the fundamental sound of your instrument. There's nothing worse that stepping on a bass pedal and immediately thinking, "Where did my bass go?" Rest assured, no matter how much you crank the fuzz or pull back the dry volume, the M84 Bass Fuzz Deluxe will keep your low-end punch intact.

Unique distortion circuitry based on a modified fuzz pedal

If you're noticing a distinctly "vintage" vibe in the M84 Bass Fuzz Deluxe's tone, you're not mistaken. Here's a cool fact about this particular bass pedal. Far from reinventing the wheel, MXR began designing the M84 Bass Fuzz Deluxe by taking a tried-and-true vintage fuzz pedal and modifying it. The result is a classic fuzz tone that's both perfect for your bass's range and tweaked to have a more modern edge.

MXR M84 Bass Fuzz Deluxe Pedal Features:
  • A great way to add grit to your tone and to thicken up you bass sound
  • Creative circuitry that's based on a vintage guitar fuzz pedal that's been modified for bass
  • Separate wet and dry level controls let you blend in the effect to taste, allowing you to preserve your dynamics
  • Hardwire bypass protects your tone when disengaged
Add the perfect touch of fuzz to your bass tone with the MXR M84 Bass Fuzz Deluxe!

Another great product by MXR!

I continue to be amazed by Dunlop MXR effects, and the MXR84 Bass Fuzz Deluxe is an excellent compliment to their other great bass effects, of which I own all of them! The Fuzz added exactly the sound I was needing, with no feedback or outside noise. Heavy-duty construction that will hold up under use, but in a small, easy to handle size. Sweetwater is the best: they carry the best products delivered with the best service!

Impressive

I picked this up for two reasons. The first being separate wet and dry controls. Every bassist worries about losing bottom end once the gain pedal kicks in, but this one retains ALL of the fundamentals of my bass. The second reason was I've owned four MXR bass pedals over the years and liked all of them, and this one is my favorite pedal of the now five I've used. Only gripe, and it's incredibly minor, is I would have liked having the dry signal being all the way down to produce no low end from the bass, but that's not necessarily a bad thing. This won't be leaving my board anytime soon.
