Well, when ordering this pedal by electro harmonix I haven't expect it to be anything else but perfect.
I originally wanted to buy this pedal after I heard how well this reissue can replicate the tone of my favourite guitarists: David Gilmour and Robert Fripp.

- Easy to use: the pedal only has three knobs. Volume, Tone and sustain. The sustain knob controls the amount of distortion and of course, as the name says sustain.
- Replicating sounds: Because Ram's Head Big Muff was used by so many iconic artists this reissue will give you the possibility to match their tones.

(Possible) Cons:
- I haven't recorded anything or played with a band with this pedal yet, but my only slight concern is that this pedal might not have enough mid frequencies. (This was a common issue with Big Muffs). But if this problem exists, you can still easily fix it with an EQ.

My main recommendation:
If possible use this pedal with a valve amp and not a solid state amp. Like any other fuzz it will sound the best with a valve amp. On a solid state amp, it can sound quite dirty (not in a good way).

Some settings for you to try out:
Fripp's Tone: Volume: 50% / Tone: 25-30% / Sustain 95%
Gilmour's Tone: Volume: 65-70% / Tone: 70%/ Sustain 90%

It's an insanely good pedal, that I would recommend to everyone!


Awesome at what it does

This is the kind of pedals that does one job, and do it right.
Pros -
It's definitely a leads beast, you'll get some screaming leads out of there - for long sustained violin-like bend (for your inner Gilmour wanabe) or crazy roaring stuff (think J mascis)
- For the price, It's a great pedal with a very subtle relationship between the knobs to craft the sound you really want

Cons -
- Even with the aforementioned tweaking possibilities, in the end, it's all different sides of the same exact thing. You need to make sure this is the sound you actually want - I would definitely recommend to test it and compare it to other EHX muffs to make sure this one will get you there. If it is what you're looking for, go for it, it's great. But don't believe all those forums that will tell you about how "versatile" it is, because it's not really, it can only be tweaked within its own very niche boundaries.

In general, I wouldn't recommend this pedal if you are looking for a shoegaze wall-of-sound type of thing (it hosts 0 MVB vibe) or for this Jack White sound that a lot of people try to achieve. And it won't quite get you to the Black Keys tone either.

So overall, go buy a big muff, you absolutely need one, but trust your ears, or just take the one that your favorite artist has and don't try to find "the best one overall", there is none as they are all so different and so good at what they do :)

If you're into J Mascis or David Gilmour - get this one and stop looking for fuzz forever.


aboslutely awesome!

When I started building my first analogue pedal board I decided I wanted a board that can play anything from Gilmour to some heavier prog-metal.

I knew I would need to have a few staple pedals - and this was certainly one of them.

Initially i thought i would only be using this for those Gilmour leads but boy was i surprised.

I did the usual - Fender Strat playing the bridge pickup with a bit of delay, then I kicked on my OD.... Boy was i surprised. Suddenly, I was getting some super expressive leads. Made a few adjustments - and i was chugging out some metal on my Strat!

Plugged my LP in and was surprised at the amounts of distortion i was getting.

All this into a Marshall Origin just on the edge of breakup.

This pedal can really do anything, really.

- Gilmour tones down pact
- Can go into the higher gain territory
- Harmonics are amazing

- you have to tweak with it a bit to get it to where you want it
- it is relatively mid-scooped - you will need to mess with the EQ on your preamp


Outstanding pedal!

I use this pedal for home studio e little live event with some friends.
It suits well different music style from 70's (pinl floyd) to modern (muse). AT both low and high gain the response is perfect. THe sustain is very long and must be fine tuned for each track.

very versatile, perfect for 70's music as for modern music . It is also very compact
