I was ready to build a 66 Triangle when I realised that not only I have no 120nf caps, but even in the biggest components stores in Madrid I can't find 'em (100 o 150, but nothing in between), so I have to wait for another tayda's order, two more weeks.
I had very clear that the triangle was the one I wanted to clone first, but now, I have no clear choice.
Green russian and Ram's head are good options, as I want it to have powerfull bass but as now we have a forum, would like to ask you about your favourite BMP, I remeber that Miro built 5 in a row, or something simlar, so please, let me know your opinion.
Having owned an off the shelf Big Muff and built a Triangle, I'm afraid to say that the genuine Muff sounded the best. That could be down to my crappy build though, it was one of my earlier ones. Since the basic circuits are pretty much identical, why not try socketing the key components and make your own version?
Black, Green, Triangle, Ram's.... yeah, all so similar, and so fifferent at a time. I think i'll build the RAM as it seems the most similar to the Triangle and I have all the components and values at home.
I have an original Red and Black, so i'll be able to compare both when the Ram is finished. I hope to finish it before next week, as the Kingslayer pcb from Madbean is supposed to get here on moday or thursday!
I went on a big muff building spree a while back. I meant to order a Mudbunny from Madbeans, but I ordered two by accident. Then someone gave me another Mudbunny PCB. Then I ordered some stuff from Guitarpcb and the guy was cool and threw in a Muff PCB. So I ended up with four muff pcbs. I built what was basically a P19, a Mayo, and Rams Head with slight variations, and my own mongrel.
My thoughts from socketing the circuits and testing, and then after building and playing with them:
1) The transistors surprisingly don't make that much of a difference.
2) They all sound great if you like Muffs which I do.
3) They are all pretty similar. If I play them back-to-back to do a direct comparison I can tell the differences. But it's mostly in the extremes. Probably like 75% of the range overlaps and even the stuff that doesn't can be approximated by adjusting other settings in your amp, stacked OD/booster/distorition or guitar volume.
So if I had to build just one muff, I would build for a generic/averagis or conservative gain. Then I would build two switches, one for the clipping circuit and on for mid-boost/varied cut. Bypass the diodes or at least one of them for the clipping, and add a mid-boost (or less cut) for the other. That would probably give you everything you need pretty easily.
Everything else is more subtle, and/or is sprinkled throughout the circuti so not that easy to change, and/or can be approximated via other pedals/amp/guitar and you won't mess with that much once you dial a setting you like.. To be honest, you can even get a lot of muffiness with something like a Rat so the myriad of official muff versions and boutique clones is really overkill.
Have built the violet rams head and Green Russian versions. Both nice and fizzy though the bass frequencies on the Russian are ideal for the brightness of my Selmer amp and give a nice full fat tone, even on single coil pickups. Had a deluxe big muff with in built compressor when I was a kid, never seen one of those pedals since - probably worth a kings ransom nowadays ... sold mine in the eighties ... doh!
I've built 2 Big Muffs that I really liked. One was the Jordan Creator, which is basically a hotrodded Triangle, and the other was the P19. I really like the way the P19 sits in the mix on guitar (but it's not that great on bass.) I'm just not that blown away, although if I mess with the transistors a bit more, it migh get better. The Creator, on the other hand, is absolutely awesome. It's not fizzy compared to a lot of Big Muffs, and the gain is manageable. I do find the transistors make a bit of a difference, my personal favorite combo in the P19 are MPSA18 for Q1+4 (input boost/tonestack), and BC550B for Q2/3 (the clipping stages). I would like to grab some BC550Cs to see if the higher gains help the P19 punch a little better.
I've got another project in the works, involving a Green Russian, a FET blender, and a boatload of DPDTs.
Well, these days I've been reading a lot about Big Muffs, its versions, and so on.
All these reading confirms what you say: the BMP circuit is extremely tolerant to values and tolerances, so all big muffs are pretty the same in a 90%, the rest are little details and nuances.
Been reading that every version can have even 20 variations, so finally decided to build one of the most wanted BMP in order to A/B it with my original Back and red american reissue, and choose the Violet Ramshead, fourth variant of Version 2 Big Muff. Liked that it just takes poly caps and no electolithics and that was one of the most desirable BMPs
