Looking great!
Navigating the website does not work for me though (Safari 8.0.4 on OS X).

Just out of curiosity, what happened with Blackspade? A year or so it looked like it was absorbed into Tab but now is back? A UM17 has persistently been on my radar so this is pretty exciting...

You must be crazy. That's way too cheap. That's hardly the cost for parts. You mad. I like you.

Will the UM25 see a return?

Something similar to the 25C with a Campbell CT12 is possible. Would be more towards the end of the year though, as we finish off a few other products first.

At the right price, I may be interested!

I'm looking forward to seeing your future product announcements.

I'm interested to learn more about the tonality of this microphone, how would this differ from say a U47 tube microphone? Looking for a third decent option for the stoodio within the following months

The best way to answer this question would be to compare what users of the originals report as the differences between the vintage M49 and U47 mics.

Electronically the UM17B is a hybrid U47/M49 build, and with over 70% of its sound derived from the capsule and transformer (M7 and BV-08), it should in theory have been very similar to a U47. But in practice, the sum of the electronic and mechanical parts (chassis, head-basket etc.) made for a sound much closer to the M49.

We have also implemented the same built-in LPF as used in all three revisions of the M49. For anyone who would need their mic to be more open up top, this could be removed by snipping a single lead on the board (no soldering needed). The polar patterns are also controlled by a potentiometer instead of a rotary switch, taking it that little bit closer to how the original worked.

What if you wanted to get the mic back to how it was with the LPF? Then you'd have to solder?

Yes! Our dealers/techs can carry out the mod on request for anyone that needs it, without affecting the microphone warranty.

Is the sound still close to the older AMI UM17 ?

Hi, here is a soundclip of the AMI UM17.

https://m.youtube.com/watch?v=_66gDMnDbpo

Is the sound from the BSA UM17B still close to the same?

I like the open and clear sound from the clip and was wondering if that is the sound after snipping the single lead on the mic board?

A lot of the UM17's sound was down to its capsule, a Chinese made K47/M7 hybrid. The UM17B doesn't capture quite as much high-frequency content (with or w/o filter), helping it to sound warmer and smoother overall.

For somewhere in the middle, it could be worth considering the Redline Mylar capsule as an option, as its sound is noticeably more open compared to the Blueline.

Thanks for your reply. You mention earlier about snipping the single lead on the mic board to let the capsule capture more high end frequencies. How much more high end frequency would be achieved. I know it is a touch question to answer, but let say compared to Neumann M 149, would the UM17B still sound dark?

Thanks for the question; it's the capsule that for the most part dictates how open the mic will be. Thiersch's PVC M7 has a characteristic soft topend with a more pronounced midrange, lending the UM17B a smoother sound compared to mics equipped with much brighter capsules. I wouldn't call it dark though; similar to the original M49, it's a very balanced sound.

Otherwise, the LPF in this circuit has a subtle tuning effect. Even though it's noticeable, it won't drastically change the character of the mic when removed. For brighter, best option is to start with a different capsule.
