I did this mod today, and I was blown away with the results. I was planning on that tone stack bypass thing when I came across this video and decided to try. Damn... if you think it sounds great on the video, oh boy, you will feel the change. Muuuch thicker sound, full range, and you keep the tone control knob, instead of just cutting out that part of the circuit out. Amazing. Thank you man, thank you very much!
@@OCCVLTPEDALS This definitely sounds good! Another way to do it is instead of a switch, use a pot with 2 capacitors and you can blend them, PLUS then blend that with the original tone knob. Then, play with different capacitors, and get your perfect mid focus control!
Dude, you are awesome. I have absolutely no background in this whatsoever, I've had friends try to explain electronics to me in the past. Nothing they ever said or showed me left me feeling like i should mess with something i valued. After watching you're video I realize hey I can do that. everything you did made sense to this definitely untrained mind. thank you.
Tip: EHX pedals in this type enclosure have a stainless steel top. It is hard stuff and can be difficult to drill through. I had better luck by buying a cobalt steel drill bit for this purpose.
I tried slightly different values. I think it was .01 and 223k. So the .01 will give you a flat mids and the 223 will boost the mids with vintage stock sound in the middle. It is also worth noting that below noon on the tone knob, the sound will be more or less the same with whatever values are chosen. These type of cap mods in general affect the high end and also sound like a volume boost when the mids or flat mids come in. I found the more flat mids to be quite versatile. The stock pedal is very bright with the tone up high. The cap mods like in the video also give the pedal a more modern flavor. I did it on a coda effects big muff pcb with the original Triangle values.
Nice! For those that don't know you can change the input cap uf on all pedals. You'll tailor the sound. You can also use different op amp for the Big Muff or transistors & the different hfe will give different results. I had one person put the wrong uf in their monitor & they couldn't understand what the bass wasn't there.

I did a similar thing with my Nano Russian Green BMP, but a little more complex. My central position is stock. One side has a 10nF paralel to C8 which makes it like the standard NY BMP and the other side has a 5.6nF paralel to C9 to make the frequency response flat. I used the same software for the calculations.
I modded two BM with this mod and the results are great! The stock tone is great when vocals have to stand out but you still want a massive guitar sound behind it, but when your guitar needs to cut through the extra mids this mod gives are a gift. Thank you!
that's cool, i love your video, and your style. If you detatch one of the pin of the first condenser you could just need one condenser instead of 2 and switch with 3 pin instead of 6, and you could attach them in series instead of parallel (by doing that you could boost the difference of potential of the board), that's the setup i use in mine, with some difference in the other components
just did the mod and its great...i installed a mod board with my switch that has sockets which allows me to put different caps without soldering and i can change them out to different values and see which ones i like the best
I found the easiest way to get a more live sound is to play it through a completely clean amp. Without guitar amp tone mixed in, sounds pretty much like doing that mod.
Amazing bro 🔥 What do you think about adding a second footswitch for the sound "stock 3.3nF+33nF"? So you can change distortion from the sound of "switch up" to the sound of "switch down" while playing.. tell me if I have not made myself clear 😅
No answer yet ? Although the idea is great. Just think it over & if you really need that mod, well then do it ! Important thing he forgot to mention: NEVER use ceramik capacitors in a tone circuit ! 🤘
You could attach the wires to a mono jack in the top with the others and wire the 'C9' wires to it, put a mono jack in your switch pedal, that way you can just use a regular lead to attach it. You could use 3 push on-push off switches like the BM has, one to turn your pedal on and off which just opens and closes the circuit, one for one value of capacitor, and one for another value of capacitor. That way you only have to drill the one hole in your BM, and you can make the switches a decent distance apart, just means you have an extra piece of gear to carry around.
I accidentally made mine gate by using a 7volt power supply instead of 9. It sounds awesome with no loss of tone or volume….. you don’t have to opened it at all also. Although you could add a var resistor so you can make it permanent.

This is awesome! I think this will be my first foray into soldering. Hopefully my board looks like yours - i have zero idea how to find the C9 connection points if they are different. thank you
I just get one of this... when i find the parts, i'll try it... can you make a video of how can we install switch for diodes mods and how can we add a boost before de muff circuit... great content mate🔥
Great video! I was thinking about doing the Tone Bypass mod (from the StewMac kit, but I’m sure available other places). Can I also do this mod to the same pedal?
Don't stop there! Build your own Muff and experiment with different transistors and clipping diodes. Lower gain transistors take you out of fuzz territory into a cleaner sustainer type circuit. Germanium, silicon, and Schottky diodes have their own character. And you can always replace the simple tone stack with a three band eq, etc. It's a great circuit to experiment with.
Would this also work on clones of the Big muff such as the Mini Muff by Mosky? I can forward you the insides of the pedal if you'd be willing to help out.
I would love to do this mod! Where would I buy all the parts I need? I'm a little new to pedal modding. (Also I love your videos! They Taught me a lot and are helping me get into pedal building, thank you!)
If I would like to change stock C2 10 nF capacitor ( accoridng to ToneStack calculator) where is it located on the PCB board ? I have 3003 Rev_E too. Why is C1 capacitor on ToneStack is called C9 on the actual PCB board?
@@OCCVLTPEDALS I thought about adding a 3 band EQ and maybe LED clipping for more volume and open sound and maybe an FAC style switch near the input to adjust low end going into the pedal before it gets amplified.
Did you do the Tone Bypass like in the StewMac kit? I was also thinking about doing that one. Looks like it’s on a different capacitor, so I’m guessing both should work.
i discovered that i have the slightly older version of this..old school power adapter,foot switch is hand soldered with no 3pdt board, and my c9 cap is a .0039 greenie cap....but i assume the mod will still sound very similar...update....I bought a current model because I didn't want to mod my "classic" NYC Muff so gonna do the mod this weekend....also the newer muffs are absolutely different sounding than the classic NYC...i have them side by side and the newer one is muffled in comparison,lower volume output and just not as good,it actually needs to be modded imo ,i know pedals vary in sound sometimes but this is very noticeable,i was shocked...i actually cant make them sound alike
Hi! Which capacitors do I have to ask for in the store? I'm a little new to this so I think I missed the information. I think is a 6.8nf and a 33nf, am I right?
Yes, you can also try another values a bit higher or lower ( higher value, higher lower mids boost ). They will probably ask for operating voltage so just take lowest - they are smaller and fits easier.
This is a great mod. Now, what if I wanted to change those settings on the fly? Would there be any way instead of the 3 way switch, to have two footswitches on either side, maybe the left side toggling 3.3nf + 6.8nf, and the right side toggling 3.3nf+33nf? Just curious if it's possible to mod the pedal in such a way where you could change the settings without taking your hands off the guitar, bending down and flicking the switch.
i don't think it matters but parts for pedals are very low voltage since you're only dealing with a 9 volt pedal...so well under 100 volt parts is the "standard" for pedals
I have a mini muff, and a bass muff, and they do not have so much space to play around, so I will be selling them instead of modding them, as they both sound too fizzy for me.
