Gyraf Audio just announced the release of their new G25 Vocalshape. An all tube recording channel that includes their new mic pre, a vari mu compressor, a tilt eq and an audio clipper. One F Sound will show it at NAMM. It is phenomenal.

Whew, man - I bet it does sound phenomenal. Are they offering a free one to the first person to reply to your post? 😎 |

… as anything Jakob makes☝️😎😎😎 Totally off topic but I totally agree with your last statement. Back in 2004 or so, as a student, I followed the instructions on Jakob’s Gyraf page (and provided schematic) to make an 1176 rev F clone. This was before any kits were available, or at least not known to me. Had to buy my own parts, make choices, tracked down an early MNATS PCB I bought internationally - learned a ton, drilled mounting holes manually into black aluminum 19 inch chassis. Anyway, got the whole thing largely working but wasn’t properly compressing and debugging that was way ahead of my skill set at the time. Decided to go see a professor in the electrical engineering department at my university, known as sort of the “godfather” analog guy there. Brought a poster sized schematic printout with me. Having no previous experience with the compressor, based solely on my described “symptoms” he circled a small portion of the schematic and said “your problem is likely right in here”. I went back to my dorm, used a multi meter to check my connections in the region: sure enough I had two cold solder joints from my inexperienced soldering (was related to diodes in the side chain if I recall correctly). I was suddenly so interested in the “magic” of analog that I changed my major and decided to focus on electronics. Basically changed my whole life trajectory, in part because of an audio guru in Denmark being willing to share some of his hard earned wisdom on this (mostly) beautiful thing called the Internet. If he reads this: thanks Jakob! |

If he reads this: thanks Jakob! The only thing that keeps Jacob from being in the discussion Of the worlds top designers is the fact that empowerd so many with his DIY projects. It threatens those of us who were in the business of selling new gear. |

Never thought of it that way, but it makes sense. For me though, gaining an understanding of what was really going on “under the hood” made me increasingly interested in different types of gear. Also, for those of us that are just serious hobbyists (or maybe semi-pro) in terms of recording, as my proficiency in my “day job” grew and my available free time become more precious (especially when wife/kids came along), it made more sense to buy gear then to DIY it (even though I love DIY and totally recommend it). So for me, I think DIY made more choosy with the gear I purchase, having a better idea of what I think I’ll like, but got me some serious GAS that I’ve never fully cured. In other words, I probably spend more money on gear overall now, not less. Maybe counterintuitive from the sales side and also a slow transition.
I’m adding the Gyraf G25 to my list! (Or at least some other serious Gyraf offering: definitely want to support Jakob’s business side and totally confident in his designs)

Gyraf's product page on this unit with some detailed explanations.
G25-A The G25-A is a not-yet-finished specialized version intended as power supply and hardware extension for the legendary Campbell Transmitter “Astrud” tube microphone. The Astrud connects through an additional 7-pin XLRf connector located on back panel. Astrud will be available only on special order and by appointment with mr. Campbell Campbell Transmitter “Astrud” tube microphone. I'm intrigued! Care to shed some light timcampbell? |

Jakob and I have always wanted to share a commonly built product so we came up with the Astrud. It is a special order, piece built microphone based on a unique tube and using one of my capsules tailored to it. It is meant to be dedicated to this preamp so it comes without a power supply, has a unique connector and is physically huge on the order of an old CMV mic. We haven't worked out a final price but it will be expensive. |

It looks great, my only reservation is, I've bought several high end "all in one strips" and there's always a couple of sections where I already have better in my rack.
Every stage needs an insert so you can go out of the unit and patch in alternatives when needed.
That said, if you haven't got into hardware in a big way and you're looking for a great voice/bass/Ac Guitar recording front end then units like this and the Tree Audio Branch II are very cool solutions.
I'd certainly enjoy demoing one.

Excited to see more Original Capsules or Mics in the pipeline. Will it be on display together with Gyraf Audio G25-A, at NAMM2024? Will it be HUGE and EXPENSIVE like this 18k USD Requiste Audio L7 Line-Level Tube Mic? Attachments:

No. We have only made prototypes so nothing for public view yet. |

I hear ya' - and we considered this across several early prototypes, at a time where we still had solid-state amplification going on for all but the preamplifier.
But as revisions came in, it got more and more clear that although the solid-state version definitely "got you there", tube-based but otherwise equal circuits simply behaved "better" - in the sense of giving you control over its sound in edge conditions. So it's now an all-tube signal path.
But being all-tube means that we have to work with quite different circuit levels and impedances: If solid-state, you generally have very-low output impedances "automatically" from each stage, making it relatively easy to interface to "the outside world" - but when basing amplification on tubes, we are looking at very different and much higher source impedances and potential DC offsets. Internally, we accommodate for this by circuit dimensioning, but these signals wouldn't survive a loop out in the external world.
So the only way to implement numerous interstage insert points would be to add extra output stages and balancing/debalancing transformers in-between stages, which would double number of tubes and impact sonics significantly. This goes contrary to my gut-feeling about the beauty of circuit minimalism.
All that said, I truly believe that - for vocal recording - you do not need different from what's here. Yes, I get ya' - perhaps for kalimba, banjo or bagpipe you'd really need different eq or a variable attack time compressor - but remember this one was made for recording vocals. Note that e.g. the eq/hpf section here is deliberately minimum-phase so fully reversible should you change your mind later (real reason is that for some reason minimum-phase eq tends to work much more neutrally on many types of voices).

Fair enough. I have a few channel strips - but since I've grown my racks of tube compressors and EQ's I don't use everything in the strips. On one strip it's the tube pre - another the solid state EQ. So I stopped buying channel strips - I have individual units with much better sonic options, especially for vocals - different singers/genres definitely require different approaches and therefore different pre's - compressors - EQ's. BUT .... if I was just starting out then a great channel strip as a front end for a DAW is a great idea and brilliant value for money. |
