    Yep. That’s the V4 with the 1322 board. The same board was also used in the V5 with the tone bypass switch, but yours is the on/off V4 version. Looks to be in good shape.

    Actually the 500k has a smoother, more gradual increase in volume, but at max it is definitely louder than the 100k in the other Muffs. Not really much difference in one or the other as far as dialing in Unity gain. The RevC NYC has a slightly deeper, more hollow bottom end than the LBM. The LBM is a tad bit less bottomy, and a tad bit more crunchy. On certain amps it won’t sound quite as ‘big’ as the RevC circuit, but both are very similar. The LBM will stand out in a mix a bit better than the RevC, but the RevC has a bit more deep “doom” to the sound if you know what I mean.

    The LBM stacks up very well against the NYC. There are a few different circuits revision made on the NYC BMP since 2000, so the difference is greater on some than others, but overall they are 95% the same.

    I think Russian Muff look best when they appear to have gone through a war :)

    If you repaint, sand the case down and put some primer on it before you paint. It does not appear the St. Petersburg factory primed at all. By V7 version 1, I assume you mean one of the early ones with the plastic door cover? If so, there are really no replacements available. You can get a sheet of stainless steel from hardware store and cut a new one with metal snips, and a bit of folding to get it to stay in place. There are pix on my Big Muff site of the original plastic doors for reference.

    Congrats!

    The modern Muffs don’t really capture that V4 sound. I don’t think you can find a better Big Muff for Corgan tones. I run mine through a Mesa 5:25 Express, on the dirt channel with just a bit of the amp gain dialed in. Seems to voice just like what I hear from Billy’s JCM on SD. I suppose many amps get that tone with this particular Muff, but it a sweet tone.

    As said, the knobs are most likely replacements. I have seen a few V2 Muffs with them, but they were modern Davies Molding replacements.

    The Muff itself may be somewhat unique. I have come across several blue V2 Muffs like this, with the flat bottom of the face circle graphic exactly like yours. Each had the exact “violet” spec circuit schematic. The violet schematic is rare because it is one of the brief times EHX seemed to follow an exact schematic for a time. Most V2s have wildly different components values, making them all sound different. The violets sound great, to me anyway, because they are not too bassy, are thick sounding for chords, but not overly grungy/muddy thick, and have a very nice articulate sound for solos. Not overly mids scooped either. They are not as high gain as some of the other Ram’s Heads, but are not overly noisy either.

    Not all Muffs with blue ink have the violet circuit, but every one I have seen with that flat bottom circle did. It is one of the more desirable Ram’s Head Muffs.

    If you look about halfway down this page, you will see a few with the exact same blue graphics, and pix of the circuit to compare, or shoot some pix and post them and I can tell you if that is what you have.

    We thought these were 2N5087 before because of the direction they face, like the A18s. I have to correct myself. I have seen a Muff with MPSA18 tranys before, but only once. A V6. I guess EHX had a batch in 78 or 79 for these V3s.

    What is more interesting is that EHX had transistor V3 BMPs, as well as V4 and V5 op-amp BMPs, all apparently on the market simultaneously.

    Just an update to this thread. After seeing a few more of these odd tone bypass V3s, which all appeared to have identical circuit components and values. After getting to examine a few, I have concluded this is a legit V3. Most pots are dated ’79, though at least one person told me he bought his in late ’77 or ’78. Transistors are odd. NPN MPSA18, not 2N5087. I have never seen those in a Big Muff before, but they were used in other pedals. All but one had the hockey puck V5/V6 knobs. One had old V2/V3 Daka Ware knobs and 78 pots. All have the old V2/V3 board, but component values in these different than most of the V3s I own or have seen. Sounds really loud, hairy and gritty, much more than any early V3, but similar to a couple of later V6 Muffs I own. Very mean and dirty sound. I like it.

    Base on this and a few other bits of info I have learned from owners and sellers in the past year, I have concluded that what Howard David thought was true – the V3 never actually went out of production during the short time the V4/V5 Muffs were made.

    Pix are really big, so you may have to drag them to your desktop to view.

    Some v4 and v5 op-amp Big muffs may have a noticable volume/gain boost when the pedal is switched off due to the fact that these old Big Muffs do not bypass the signal even when off. The signal still goes through and is amplified by the active op-amps, which can sometimes add a gain boost.

    I think there is another thread here about this same issue, but as far as I know, adding a 3pdt true bypass switch is the only way to eliminate this problem.

    We nick named it that here in the US because it had our Civil War colors, and the old west looking font that was definitely not very Russian. Calling it a Civil War BMP makes about as much sense as calling the V2 BMP face a Ram’s Head, but those names have become somewhat standard now.

    Yes. Most large hardware stores will have them. If they don’t have the 1/4″ length you can get 4×3/8″ length. They fit too. They will be called PH Phillips, or Pan Phillips, and come in small bags of 20-24 pieces.

    I thought I should add the G4 Big Muff to this thread and make it up to date.

    Version 13 – “GERMANIUM 4” BIG MUFF (2010) – This is not a traditional silicon based Big Muff circuit at all, but as the name implies this is a new BM class – the GERMANIUM Big Muff. No deep, scooped mids, or huge Big Muff tones here. The other Big Muffs have that covered. This is a whole new range of muffled fuzz tones. Essentially this is two pedals in one – a fuzz type Distortion and an Overdrive. This is a knob twiddler pedal, and for anyone familiar with the wide range of pedals Electro-Harmonix has made throughout the years, this is very much in the style of classic EHX, almost an experimental fuzz unit. The Overdrive side dials in a nice light to moderate drive sound. Good for light drive lead tones, and for boosting a Big Muff.

    The Distortion side is really a very tweakable Germanium fuzz type pedal. It does similar fuzz tones as a Fuzz Face pedal, though the G4BM has it’s own unique tone. The volts knob lets you get into the dying battery sound of a traditional fuzz, and playing with the bias and gain knobs gives a wide variance of the G4BM fuzz tones. Switch on the Overdrive side, which runs in series with the Distortion side, and depending on the settings, you can get a nice warm boost to the fuzz, or can kick it into screaming overdriven fuzz territory. It smooths out the fuzz while still keeping the over the top splat at high gain.

    Sorry guys, but I don’t know the exact Russian part number for those black TO92 transistors. I have seen dozens and dozens of them, and none have any markings other that the painted dots. The metal can TO18 cased tranys they sometimes used were numbered KT3102E, KT23102E, KT9108, and 5102E. KT3102E seem to be the most common. NPN 2n5210 equivalent for those. No idea about equivalents for the others. I emailed back and forth a few times with a guy who used to work in the factory that made the Sovtek pedals for EHX in St. Petersburg and all he could tell me was that they were “E” type and that they were supposed to be similar to the transistors used over here for the USA Big Muffs. I have an exact clone of a Civil War Big Muff from Stomp Under Foot that uses 2N5088s, and I can barely tell the difference between that pedal and my two original Civil War Big Muffs. 2N5088s are probably the best transistors to use for any Big Muff currently.

    That’s exactly why I believe EHX won’t do it. But I think EHX is in their own pond, and has always been. And I think reissues are a different animal and serve a different customer than boutique pedals. I suspect the boutique pedal buyers are not the crowd buying all these reissues anyway. They will likely be the ones who bash them on TGP and HC for not being accurate replicas :)

    It would just be nice to see EHX reap the benefits of their own past work, but as I said, I don’t think they are interested.

    Which clone did you buy?

    I think DiscoFreq posted an ad with that same Bad Stone somewhere here before. The mummy graphic came before the black and orange, so I would assume the pcb is similar to the Mummy version. I like that the ad copy says 1080 degrees instead of 180 like the other ads. I guess this version makes you dizzy when you hear it!
