It's a big muff for bass

Nothing more can really be said. Personally i use it with relatively low sustain for distortion and fuzz. Wether or not a bass player needs a big muff is up for discussion, but as i play in a trio band the answer is definitively yes. It sounds like a big muff and it functions like a big muff. And the big muff works and sounds great.

My favourite bass fuzz

This is a masterpiece, love the sound of the fuzz itself, but with the switch to the right you get a very nice blend knob to keep the low end alive

The huge, fuzzy, green box sound you know and love, all wrapped up in a tiny little package.

Yes it says "Bass" on the box. Yes it says "Bass" on the case. Yes this is technically a "Bass" pedal. However, it does guitar, real well. I started a search a few years ago for at least one fuzz pedal, as I did not own one yet, to add to my board; and yes I'm aware I might have a Gear Acquisition problem. Turns out I'm really picky when it comes to fuzz sounds. After trying a bunch of pedals, and hating most of them, I found two that I not only liked, but loved. The EHX Nano Bass Big Muff Pi was one of those pedals. Now that we've gotten the obvious use out of the way, and how I came to trying this thing out, let's talk about THE sound for guitar. It has the big Sovtek sound, mashed into a "normal" sized enclosure, I believe by a stampeding heard of Kamchatka Vodka drinking Russian Brown Bear/Woolly Mammoth hybrids. It sounds amazing, and glorious. It can go from nice smooth distortion, all soft and cuddly, like a properly brain-tanned bear skin blanket, to super compressed, crushed, and infinitely sustaining fuzz, that just feels like a felted woolly blanket, full of a myriad of small creatures, chilling around a camp fire under a new moon. As I received this as a Yule gift 25Dec2016, I have not tried it out on all of my gear, much less in every configuration I have. I have played it through my Fender Champion 600, with a 6l6 output tube, and a paisley silk grill cloth, using my MIJ E-Series Fender Stratocaster, with Torres Engineering BluesKaster Deluxe electronics. It sent the 600 into a beautiful place where Wildcats, and Dragonflies, play with children of powerful magic. It was the best that amp has sounded so far, full of mid range tone. I can't wait to pump it through my Fender Hot Rod Deville 212, and see if I can stop messin' 'round and get all numb, while waiting on the train. This is the box to have if you can only have one fuzz.

good fuzz, takes dialing in

works well to get great fuzz tone, requires a lot of dialing in to get just the right tone and works best when following up on a lightly cranked tube screamer.

Not just for bass

I'm a huge fan of the Sovtek Big Muffs, but the black one is a huge pain in the ass on my pedalboard (reversed in/out jacks on the BACK? No AC power?!)

This little dude is basically the same circuit with less than half the footprint. Very happy swapping the two out!

Nice one

I brought myself one to get the Cliff Burton bass sound, but now I use it more often for guitar then bass, because of the dry switch you get always a real nice mix of both signals (clean and fuzzy) and I get really warm but also really harsh tones out of it. Also when i play Hysteria by Muse with it, everybody just says awesome :p Aaaaalso it sounds really nice on guitar :D

Very good, but the boost...

It's a very good pedal, but I miss the boost option present in the normal version.

Big Bad Dog

This is a nasty dark muff, use for milder muffing, higher gains remind me of old school muffs

Very awesome pedal!

I love this pedal has such a great sound! Can't wait to order mine!
