The main reason for the mods is to match whatever version you may have, if you already have one with these mods.

From my understanding they are switchable options that will come standard with the M49v and not options that must be requested. Nope. I would get in trouble for posting unreleased marketing info so just trust me on this. I just want to correct any misinformation. Let's cut through the noise: Both switches I suggested to Neumann (low cut, cardioid only) will come standard in all M49V. The only build-to-order (BTO) option a customer has at time of ordering is to have the switches positioned to "low cut = bypass" and to "cardioid-only". Unless so ordered, the switches are set to "30Hz low cut" + "multi-pattern". As I did with the U47FET and the U67 Reissue, I will publish a thorough review of the M49V, including detailed comparisons to the corresponding vintage version M49 soon. |

Don't know if you can answer this (now before your "review" & before they print the info out) but does the non-AC-701 tube have your approval? |

Quoting myself here cause I pondered on it & you really don't have to (& don't think you are going to ) answer it. I think Neumann is doing it correctly: Since there will be NO AC-701, they need the Pope's (your) Blessing in the final sound. And I'm pretty sure they're going to work on it until it sounds like a 49 to you. I mean Horch (originally another mini-valve) & FleA (not sure what they use) have come somewhat close. So, with a REAL Neumann capsule & all the rest of the circuit being Neumann, I'm looking forward to what they come up with!

I recall reading something along the lines of in the M49, the capsule and transformer have more to do with the sound than the tube itself. Looking forward to hearing Klaus' full review.

The "noise" is understandable though.
For those "in the know", this is similar to anticipated arrival U67 Reissue- Before it landed...
And more of a tech stretch for Neumann to do.
(Unless they're sitting on a lot of the original tube)
I'm just hoping some high end studios, in Southern California, will have them available as an eventual option.

For any mic the Capsule and transformers are going to be the biggest contributor to the sound but most will argue the amplifier as a whole and the tube in this case is probably going to be the third biggest factor to the overall sound. |

What I was referring to was a statement made by Klaus on another forum, which I tracked down: "The triode sub-miniature tube, curiously, plays a relatively minor role in defining the timbre of the M49, unlike the tubes used in the U47 or U67." So apparently the tube doesn't play as significant of a role as the tube in a 47 or 67, which is promising for the reissue. |

I'd say it does.
And, as I stated before, there are some "mini" tubes out there & they've probably found one. Being that there will be no AC701, & that they'll be charging the price they are, they're making sure the presentation is flawless. They're probably getting feedback on sound comparison with an AC701 M49 from the top mic people in the world.

If what Klaus says about these tubes is true, and I have no reason to disbelieve him, it seems that would potentially open the door to reissue any of the Neumann mics that used the AC701.

I could be wrong, but for some reason I am sure that this will not be a limited edition and will not come with an ac701 tube! And all these rumors about pre-orders and limited editions look like marketing tricks. "Sell your kids and your kidney and pay for the mic !!faster!! or you'll never buy one in your life." Wait a minute. Pay for what? For a microphone about which there is no information? Where the hell are the specs? The microphone has not yet been officially presented, but is it already possible to pay dealers for it? It feels like someone is getting a coin for spreading this hype on GS.

So it seems there is still some confusion about whether the switches will be able to be adjusted by users.
The information my dealer just received from the Sennheiser/Neumann rep was that they have to specify on the order if I want it with the the HPF bypassed and Cardiod-only option, "as these options cannot be changed by the customer".
I am assuming these options are on switches inside the body of the mic, and will be easy to switch by the customer, by opening up the body of the mic, and moving a dip switch.

I'm not a mic guru like Klaus, and I really have zero experience changing out an AC701 to a different tube since they are soldered in. The only thing I keep coming back too as I think about this is that every mic that's been tubed with an AC701 has been magic. Absolute magic. SD, LDC whatever.... That's a bit too coincidental for me to say that the tube is not that much of the sound. Color me disappointed with Neumann not using a 701, but trying to keep an open mind.... |

I hear what you're saying but, correlation not necessarily meaning causation, there could be other aspects correlated with those same mics that are the actual cause of the "magic". It's entirely possible that the type of circuit or transformer, that is necessary to work with the AC701, is the real cause of the magic. It could be that the capsules, made during the same time period that the AC701 was used, were voiced in a certain way particular to that time period or manufacturing method, and are thus the real cause of the magic and not the AC701. I'm not saying I'm an expert on any of this stuff, but I know enough to know that if Klaus is saying the AC701 doesn't matter that much, that gives me real reason to sit up and pay attention to what might be possible. There are some really cool mics that used the AC701, and it's very intriguing to think what might be possible with a M49 reissue or reissues of other AC701-based mics. |

I was thinking if anything this might be a market test for a Neumann U47 with a tube substitution. The 47 has a much larger market and as I said before the market for a M49 is smaller and more specialized. If a non AC701 is excepted and some of these customers ask for an M50 they will probably think a 47 with a different tube and the Neumann Badge will be accepted. |

Yeah, well "Neumann not using a 701" just ruled it out for me. Money back in the RV fund, much to the wife's joy. |

I have yet to hear of significant success stories with that in mind, and I think that would have surfaced on the horizon if there was. There are a ton of 54's, 269's, 49's, 50's that need re-tubing. One would think that if there were a direct replacement, that they would be getting some interest. I have not heard of it. But again, I don't know all on the tube fronts. To the best of my knowledge, Klaus replaces AC701's with.....guess what?  |

OTOH, no rocket scientist has youtube'd us a list of all those thousands of submini tube types that DO NOT successfully replace an AC701, so there's plenty of room for an aspiring market cornerer to spelunk gold.

To the best of my knowledge, Klaus replaces AC701's with.....guess what?  I agree that "why hasn't this been done before?" is a reasonable question to ask in regards to skepticism about all of this. I still am skeptical. However, my skepticism got turned down by a not unappreciable amount when I read that quote from Klaus. I think I'd trust that guy over maybe just about anybody when it comes to this stuff. If he's saying what he said, I'm willing to listen in ways that I might not if it was just Neumann throwing some marketing speak out there about how they've found a 1:1 replacement. The problem that Neumann will have is that, even if they do achieve a 1:1 replacement for the AC701, they'll be putting it in a brand new mic, which introduces additional variables which will make it nearly impossible to satisfy any detractors. The real test would be to replace the tube in an old mic with a new and provide before and after tests. Even that, though, would invite gotchas like "the mic was in a slightly different location than before" or "it was a different performance" or whatever. I'm still interested though. |
