Good morning!
I bought a Big Muff Deluxe for bass.
I plugged a power supply with positive central (not negative) and i think i have fried the protection diode. I saw it when I have opened the pedal to see if there was a battery inside and it was a bit broken, all the rest of the circuits look ok.
However, after that, I plugged different batteris and active and passive basses (so the broken circuit of the diode should be not included). The pedal works, as the lights turn on when i switch the foot controls, but the audio signal, connected from input to output does not pass through the pedal and the amp is mute, like if no sounds arrives to it. The whole signal is “mute”, even with lights and effects are off. (i attach a photo)
If i plug the bass on “output” and the audio exit on “direct out”, it works and the audio signal goes to the amp. If in this configuration I try to click the effect controls, the audio goes off (photo attached). If I plug the bass on “input” and the amp exit on “direct out”, the sound does not reach the amp.
I suppose there is a problem on the “input part” and I do not know which are the causes (wrong polarity last time? other reasons).
Considering this, please I have a few questions:
The warranty service could cover the diode damage/substitution? If not, how much is the substitution of this piece?
The warranty service could cover further damages in future, not considering the diode?
What about the general problem even if I plug the battery (sound does not pass through the pedal, even if it is off)? Could the problem be caused by other reasons or because of the wrong polarity on that episode? It could have cracked other circuits? Could you solve it and for how much?Thanks in advance,
Best regardsHello,
I recently purchased a Vintage big box Deluxe Big Muff Pi.
PCB marked: E3054C (short circuit board)
Version: Parallel/Series Switch, Blend and Comp Outputs.The model I have is 240v (with 3 pin AC cord).
I would like to convert this to 100V AC input (Japan) OR DC power.
Has anyone converted their similar unit to a different voltage or supply type?
At the moment the unit produces some fuzz sound using 100v however the compressor circuit simply distorts at low volume.
I could change the internal transformer, however I would need to know the operating voltage of the pedal internally which in the current circumstances I cannot test. (Assuming the current transformer steps down to a ratio – 240v to X, rather than ANY input voltage to the required voltage?).
Thank you for any help and experience you can provide!

I have a Big Muff Pi V4 that I purchased around 1980, which worked really well for a number of years. Recently I tried to use it and noticed, as with other forum users, the signal from the pedal is stronger than when plugging the instrument directly to the amplifier. However when I engage the foot switch I no longer get the rich tone but rather a really weak distorted sound, like the sustain is on full, but the volume is basically non existent. I changed the 9 volt battery however the same problem exists. When I flip the by pass switch there is no change. Any ideas?
Hello all,
New bass player and this is my first pedal.
I have a 5 string bass that has passive pickups but an active bass EQ built in. (9V powered) When I activate the crossover on the Bass Big Muff Pi Deluxe, it buzzes like crazy. Has anyone experienced this or know if the internal EQ could be messing with the Big Muff’s crossover? I don’t have another bass to experiment with.
Thank you.I received the pedal new from Guitar Center online yesterday and when turning the drive knob clockwise past noon it has a scratchy sound, but only when turning, otherwise it works fine. I was reading on the Talkbass forum that this is often normal with drive/ sustain knobs.
I also have a bass big muff pi that I’ve owned for many years and the sustain does the same but functions perfectly. The BBM was purchased used but in mint shape but I never really paid attention to the scratchy sustain.
Any insight is appreciated. Thanks.Hi,
I have a Deluxe Bass Big Muff Pi. One of the things which drew me toward this fuzz pedal was the Blend feature, so that I could maintain a powerful bottom end on my bass while using fuzz.
While the bottom end is retained, I seem to be struggling to get a heavy fuzz. If I go for the heavy fuzz I lose the bottom end. The blend seems to require a lot balancing rather than me staying I want X amount of clean and Y amount of fuzz as you’d get with a blender utility device.
This does means I have resorted to using a blender pedal to mix in my clean signal in order to maintain bottom end, but to get the full fuzz I desire.
This seems like the Blend feature is completely useless on this pedal if I am still needing to use a utility device to blend my clean with the fuzz, to maintain my bottom end but to get the massive amount of fuzz I want.
Surely there’s a way to have a lot of fuzz and keep a powerful bottom end, otherwise, why does this “deluxe” feature even exist?
Does anyone have any advice on how to use the blend properly to maintain a powerful bottom end with huge fuzz? Ideally I do not want my bottom end to drop out at all when the pedal is engaged, and I want the maximum fuzz this pedal can pump!
Thanks,
LeeI’ve just acquired one but currently aren’t in the same place as my bass and amp but want to check that it’s working. Should the LED come on when the pedal button is pushed without being connected to an amp or does it need to be connected for the LED to work/light up? Sorry if this is a daft question but just wanted to make sure it is functioning.
Topic: EHX Big Muff Deluxe pi query
Hi!
I am wondering, is the bass boost function on the Deluxe muff the same as the one on the Bass Big Muff pi? I am a bassist and have used the BBM pi for years… it is by far my personal favorite of the muff range but I like the look of all of the features on the Deluxe Muff pi. If the functionality of the bass boost/tone knob is identical on both pedals I would certainly buy a deluxe muff asap!
Any light anyone can shed would be much appreciated…
Thanks!
