Electro-Harmonix Bass Big Muff PI

Quit simple it is.
Jus volume -tone & sustain.
Also got a switch with dry/nota, /boost.
I have the graan american.

I just can't get my sound out of it.I use a japanese Fender precision bass.
I find that you can only use it in it's over the top settings.
So only to have abig phat fuss.
But than there is a sort of envelope filter wich makes ir unpredicatble.

For just a punch it is not working.You can better use your VST ampeg settings.

Always did it's work.
Battery only.

Never had to deal with 'm

I play rock/country/indie-rock.
Play for 5 tears now.Before I played 12 years guitar.
I am gonna sell it
I need punch.
I am gonna buy tech 21 bassdriver di
I don't use this one

This pedal is pretty simple. Not much has changed from the other versions of the Big Muff. 3 Knobs - Volume, Tone, Sustain. One toggle switch for the three modes of this pedal - Bass Boost, Norm, and Dry. I found it to be pretty easy to find the tones that I was looking for.

I play a Marcus Miller signature Fender Jazz bass through a Markbass Little Mark II and Ampeg SVT-610 HLF. I was very excited to see that EH was coming out with this pedal because I've always loved the Big Muff sound, but have never enjoyed the loss of low end that is typical with any fuzz pedal. I feel like the best thing that EH added to this pedal is the toggle switch.
I dialed in the settings that I normally use on my old Russian Big Muff (Volume - 12 o'clock, Tone - 3 o'clock, Sustain - 4 o'clock) and put the toggle on Norm and sure enough, there was that familiar sound.
I then flicked the switch up to Bass Boost to give it a try. In my opinion it muffles the sound a little too much. It definitely boosts the low end, but even with the tone knob almost all the way up it's a little too muddy for my own personal taste.
Lastly I tried the setting that I was most excited about: The Dry mode. This is by far my favorite setting on this pedal. What it does is mix in some of your clean signal with the fuzz and the result is an awesome, beefy fuzz tone that has just the right of low end. If you are looking for a tone similar to that of Chris Wolstenholme of Muse, this is the setting you need and the pedal you want. This pedal is also surprisingly quiet for a fuzz pedal. I'm not saying its silent, but isn't ridiculously noisy.
The only reason I dropped this to a 9 is because while it does what it say I feel like the Bass Boost setting is a little too much of a boost.

Built like a tank. No more chicken head knobs like the Russian Big Muff had, so you don't have to worry about moving them should you accidentally hit them when you hit the switch.

Haven't had to deal with them.

This is a great pedal. I've been playing bass for around 11 years and I feel like this is the answer to my fuzz needs. I mostly play rock music. The bands that I have toured with have primarily rock/indie rock bands. My main setup/pedal chain right now goes Marcus Miller signature Jazz bass => Boss TU-2 Tuner => Aphex Punch Factory Optical Compressor => Ernie Ball VPjr => VooDoo Labs SparkleDrive (for boost) => EH Bass Big Muff => Tech21 SansAmp Bass Driver DI => Markbass Little Mark II => Ampeg SVT-610HLF. Another great this about this the fact that it is not huge like previous Big Muffs. It is the same size as the Little Big Muff. So now I have more room on my board to add something else. I would definitely buy this again should it ever get stolen. The Dry signal is killer, plus you can also switch to the Norm mode if you want that original Big Muff sound, or if you want massive amounts of low end, flip it up to Bass Boost. It's probably one of the most versatile fuzz pedals out there, which says a lot for fuzz pedals. I highly recommend it, I'm sure you can find the fuzz tone you are looking for with this pedal. This is my first review, so sorry if I rambled too much.

The Bass Big Muff is very versatile and the tone and sustain controls are quite responsive. The real winner is the three way mode switch. The Dry mode mixes the grit and sweet break-up of the Muff with your clean tone almost to perfection. This is the mode I use the most, since you can make-out the detail of your playing with the heft and push of the Muff. The Bass Boost mode works great for all out buzzout destruction, since the Muff shines with the tone level past 12 o'clock. I don't find the normal setting very useful though, since it's somewhat too thin for my tastes.

I run the Bass Big Muff with Fender American Standard (U.S. made) Precision and Jazz basses through a 1970's SVT head and newer 90's SVT 8x10 cab. I put the Muff in front of an EBS ValveDrive which goes right into my SVT head. I highly recommend the EBS ValveDrive, by the way! Anyway, the Bass Big Muff is by far the best sounding bass fuzz or distortion I've played with or heard. This pedal has a simply lovely break-up, thickness, and heft that makes my SVT go into absolutely killer saturation and searing overdrive. This pedal really pushes your amp and works great for music like posthardcore, metal, or punk where lots of dynamics and heaviness are called for. I'm really impressed how natural and organic the Bass Big Muff is and how it builds on the strengths of my amp and basses. I love the sound of the old Russian (big green) guitar big Muffs and I think the Bass Big Muff comes pretty close to this sound, though it falls just a little short. I wouldn't resort to using the Russian Big Muff for my set-up, because I tried and it robbed my bass of its low-end. I'm not sure how the Bass Big Muff sounds with solid-state amps (which lots of players use), so I'd try this pedal out in this case. I use an SVT Pro 3 as a back-up, which has an all-tube pre-amp and solid state power section and the Bass Big Muff still sounds awesome. But I can say hands-down that this pedal is really tops for an all tube amp like mine. You can really hear this pedal push the hell out my amp's tubes. I get really smooth and highly usable feedback a la Sonic Youth or Unwound from this pedal too.

I use this pedal all the time live and haven't had any problems. I use a 9 volt adapter plug, so I don't know how thirsty this pedal is with batteries. Its really solid and has simple, sturdy controls, so I don't see any reliability problems yet.

Haven't had to use customer support, so I don't have an opinion.

To sum up, the Bass Big Muff is an excellent match for kind of posthardcore/mathrock/spazzcore music I play. Those looking for really aggressive bass tone and distortion should be really happy with this pedal. It's a permanent part of my set up and sound now and I've played with plenty of rigs and pedals in my 20 years plus playing. I would definitely have to replace it, if I lost it. Players who are not into heavy or aggressive music may not find this pedal useful, since it has a very rich, full, and saturated sound. But at low sustain levels it does give your amp more balls and umph without too much break-up, but what fun is that? One big point though is that the Bass Big Muff is not a bass overdrive pedal. I've found there's a clear difference between fuzz/full-on distortion for bass and tube/pre-amp overdrive. This pedal does bass fuzz and aggressive distortion incredibly well though. I recommend you try the EBS ValveDrive, SansAmp Bass Driver DI, or crank an SVT (without going deaf) to hear bass overdrive.

This is my first "real" bass effects pedal, having given up on a Korg all in one a while back.

Three knobs - volume, tone and sustain. Plenty of bottom end. I run the volume between 10 and 11 o'clock, tone at 1 and sustain at noon to get the sound I was after. Easy to mess with and get the tone you want.

I use this with a Fender passive American Jazz Bass through an SWR 550x amp with a Peavey TXT 410 and Carvin 115, usually have EQ sent to boost midrange at 2 o'clock and aural enhancer on. It's quiet as can be, not discernible extra noise. I bought this to use on the Chili Peppers' Dani California. It thought it was very easy to come close to Flea's sound on the chorus. Then I thought what the heck, we'll try it on the Rocky Mountain Way guitar solo, along with my amp's Subwave Octaver. Sounds very cool, instead of the keyboard synthesizer. It's not anywhere near a synth, but the combo is kind of thick and warbly. The crowd like it anyway.

I have to say I did not like the overall sound without the little switch in the bass boost position. In other words, I didn't care for it in off or dry modes.

I have used it on only one gig, but that was without a backup. The pedal seems VERY solid, metal casing and all. The little toggle switch worries me a little, like it could get broken off, but I'll just have to treat it nice.

I've had no reason to call customer support, but I will say I was unhappy with both Guitar Center and the EHX web site for not identifying which power supply would be required for it. Both more or less pointed me to the wrong one, which I bought and had to return. It uses a Boss power supply oddly enough. But the only place I found that little tidbit was in the little instruction sheet that came with it.

The Mediocritones play classic rock, 60s to today. I think my amp has real solid tone, I don't need many effects to get the sound we need, but I do want to pick up a wah pedal or auto-wah sometime. I've played guitar for over 30 years, bass for five years, gigging for three. Used judiciously, when distortion is called for, this should be a great pedal for years to come. I'd buy another if it broke or got lost. I compared it to Boss and Ibanez, but just liked the fullness of the Big Muff better.

This is an update on my first review.

After comparing this with a regular Big Muff, we could confirm that the tone is really different indeed.

It has much more big fat presence.

It really adds harmonics pitched for Bass and it actuall doesn't work very well with guitar because the tone is mainly focussed on bottom.

Even in normal mode, it doesn't sound like a regular Big Buff at all. It sounds much better with a bass as it should.

If the tone knob is on the left side there is plenty of bottom available. The more you turn to the left, the more bottom you have. The awesome thing is that it does something to the mottom. It sounds very gutsy and organic (in the sense that it sounds lively, not like an organ keyboard).

When you turn the tone knob to the right, the sound becomes brighter indeed but also leaner in the bottom. That's when the Bass Boost mode comes in handy.

It really sounds like nothing I have ever heard before. When playing single notes it can really sound awesome and BIG. And that's how it shines best. While playing chords, it can deliver a big crunchy hard core muff sound.

It is a modern sounding pedal indeed, but it's very far from all other overdrive/distortion pedal I have tried in the past.

It makes me want to play old school psychadelic rock and funk.

I garantee that you will hear this pedal a lot on stage and radio very soon.

After years trying real tube distortion pedals like Blue Tube, Budda Fat Bass, and some China distortion pedals from BOSS and Ibanez, I finnaly found a distortion pedal that gives me new, original and inspiring sounds that I can use.

I prefer the cheaper Bass Big Muff. I use it a lot with my Markbass/Avatar rig. It matches perfectly.

I own no other distortion pedal then the Bass Big Muff at the moment.

Oh, one last thing, the Sustain knob does just that, sustain your note for ever, even if the actual sound pressure is not ear popping.

Deffinitely a keeper.

I like the new die cast Electro-Harmonix pedal line.

I use to own a Russian Big Muff. I thought it sounded good, but I didn't like the reverse connections nor the silly volume pot which maxed at 9 o'clock. I also don't like the cheap connectors on Russian EH pedal in gendral.

The new die cast lines has the same connector as you would find on an Ampeg amp. Nice touch.

The new Bass Big Muff has an extra (Dry, Normal, Bass Boost) switch which allows interesting combination for bass application. Also probide a Dry out for better control in the house PA.

The 3 usual knobs are the same as the Little Big Buff. It doesn't mention if the tone know is tuned differently (for Bass) then the Big Muff

Big bass fuzz sound. Very impressive. Does not require as much tweek on amp as original Big Muff.

I didn't use either Russian or USA Big Muff with guitar, so I don't know if the Bass Big Muff has better or worst harmonically.

I would believe the gain circuit is based on the USA big muff.

It doesn's swallow the low end as much as the russian Big Muff. Especially with the Bass Boost option.

EH hit the mark with this making it really usable with bass.

The Dry option lets add fuzz to your dry signal, which

The Normal option is similar to the Big Muff (did not have a chance to compare)

The Bass Boost allows to get clear fuzz but with some bottom still.

I use the 3 options. The dry options is really awesome. You can keep the bottom and natural sond of your instrument and add just a bit of fuzz. Note: The dry signal is really not affected, so if yu have a good amp, you don't loose the sound quality of your instrument. It's very original.

The bass boost allows you to crank the fuzz to max, the tone on the right side and enjoy the full effect while keeping a reasonable amount of low end.

Nice die cast pedal, best connector on the market.

If you want Big Muff sound for your bass, don't look further, try this one.

With the new die cast line, my opinion about Electro-Harmonix is growing.

I always admired the suond of their pedals. I use to own a Holy Grail, a Small Stone and a Pulsar. EH pedals are the best sounding pedals for the any price.
