More than Fuzx


More than Fuzz.this pedal seems to do it all.has a noise gate also.a high and low switch just starting to learn.just adds to versatility. A looper.haveing to learn how much it can be applied.variations of fuzz seem limitless.Love this pedal.can replace at least three.



It's a good pedal.


I think that this pedal is a good one, and I definitely would recommend it to anyone who has a nice clean channel who would like wide tone control on their fuzz.

This Pedal Rules!


This pedal has everything that made the classic pedal famous and just a little extra sweetness. Its mid range EQ is wonderful and the sustain it holds is superb. Another great feature is its adjustable noise gate that can still be as loud or as quiet as you want it to be. If you're a fan of the original but want more out of it, then this is the pedal for you. I'm a staff reviewer for Sam Ash.

Sweepable mids in real time, adjustable attack, sweet sustain. This pedal leaves little to be desired from a sustain/distortion pedal. Rugged, customizable and easy to use, it can truly distinguish one guitarist from the next. This is a real hands on review by Chris at Sam Ash Charlotte.

I found the added features such as bass boost and Mids features a real plus. Still has the classic fuzz tones but with more control and options. I am a staff reviewer at Sam Ash Music.




Very awesome Distortion pedal!


The Electro-Harmonix Deluxe Big Muf Pi Harmonic Sustain/Distortion Pedal is a very cool and versatile pedal. You can get the original classic big muf tone as well as tons of new ones. You can have a warm overdrive to a nice fuzzy fuzz. This is a real hands on product review from Scott @ Sam Ash Queens

The Ultimate Fuzz!!


Everything you need and more packed into the Deluxe Big Pi. Incredibly useful tones. Build quality is superb, feels solid in hand. Provides what the classic does and then some. Build in noise gate keeps the signal quiet. Perfect gift this season!! This is a real hands on product review from Christian @ Sam Ash Columbus.

New Version of a Classic


This is the latest version of a the long time favorite. This one features true bypass and a built in noise-gate to reduce noise. The controls allow you to dial in everything from classic fuzz to warm overdrive. Great value for a pro quality pedal.This is a hands on review from [email protected] Sam Ash
