I don't think the Big Muff is a bad pedal for live performances. It just takes a few months of performances to discover the right sound. Other bands have used it live such as Bush, or STP.
dean deleo doesn't use a big muff or any dirt boxes other than an all tube SIB varidrive as a slide boost. I have talked with that guy for over an hour after an army of anyone show and I know all about his gear preferences. His live rig is VERY well known and his studio tones are a surprising amount of weird, off-brand amps turned up to meltdown.
did you call Bush a band?
Besides, someone found a way to make it work
"oh yeah, I am youtube video kid and I know so much better than the old soundman because I watch videos with limited bandwidth... whoopdeedoo! I told him."
okay dude, dave gilmour invented that trick with a colorsound overdriver AFTER a muff I think back before even I was born, but it really only works in a very limited way and it adds noise to an already noisey distortion, butting the mid boost BEFORE the muff will be noisier...
you want a big muff? just get the little big muff, its 90% the same pedal, the main difference being some miniature surface mount parts that are full size, thru hole parts on the NYC (I would say get the nano, but maybe its all surface mount aprts, I dunno if EHX cheaped out more on it, never repaired one). If there's a difference in performance in another circuit there won't be in a muff because its clipping sections are like a fucking sledge hammer -- with the stacking trick I have always thought it seemed a little nutty to get a pedal with no midrange and then add more circuitry after it to try to add some midrange back. Isn't that like driving 5 miles north to find an onramp to drive 10 miles south? Just take a different road. The big muff is a cool idea and some EHX versions sound ebtter in a band than others but none are particularly useful outside the studio. Go cheap or go with a modified boutique. I ahd a SKreddy Mayo that was pretty decent in a band contextif you were careful and being NOISE FREE it definitely could survive the stacking tricks better than an EHX muff. I also had a copy of a mayo froms tomp unerfoot and that was killer. That guy is a great guy though he's really jacked the price of his pedals up now. You should chat with him though because he is very knowledgeable and friendly. Thing is, operative word is HAD. I've ahd a geen russian, a balck russian, a rams head, a NYC, a mayo, a stomp underfoot and on and on. They are all gone and I never miss them.

try some other stuff and even some more expensive, boutique type muffs too... and pay as little as possible for the mini-big-muff because the EHX stuff has shit resale unless its old
I'm tryig to be helpful and get you the msot for you money, but if you wanna be combative and not just go "I think i will try the muff anyway, thanks for your observations though, I'll reread them if i can't get the muff to work for me" then keep going and I will taunt you a second time.
But seriusly? having looked at your personal equipboard I think you may wanna lay off on effects and save your money for a tube amp. You really aren't going to appreciate any fuzz or muff tyle pedal without one. Theya re not solid state friendly pedals, man. They wanna itneract with the variable impedance load of a dual triode in roder to really 'breathe'. These are all discrete transistor devices and behave somewhat differently than a DS1 that's driven by an IC like the headphone amp in your phone. I propose that what you were going to spend on a big muff and a TS9 to goose the front you put into your savings account to start the nest egg for a tube amp in 6 months to a year (remember to add money to the account monthly).
