My mic has the IOaudio transformer
That tranny is darker than some, but that seems a moot point now, because in your more elaborate reply (thanks for that) you wrote:
The DU67 is performing great, it sounds like I'd expect a 67 to sound.
I have been reading about how some mods that remove a part or all of the feedback circuit result in a brighter and more open sounding 67. As a vocalist producer and engineer, I'm always obsessed with improving my sound, even if that means customizing or modding my gear to achieve it.
Yes, it will be brighter. "Improving" is a whole other matter. Many would disagree with that. But yes, in the end it's all a matter of taste.
I do miss Danny's reskinned capsule, the newer Neumann cap doesn't sound as sweet in the higher frequencies as the older darker reskinned capsule did; but the new capsule sounds great as well, just not as sweet.... For all practical uses I'm sure I'm splitting hairs
Interesting that Dany's reskinned capsule sounded sweeter than a Neumann.
I can almost guarantee that after the filters have been removed, the Neumann capsule will sound even less sweet.
Also, the total difference after the operation will be beyond splitting hairs. ;-)
But now I've stayed with the Sony C800G, and DU67 as my main choices for vocal records
Those are are pretty "yin and yang" since the C800G is very (!) bright on top. That said, the capsule in the Sony resembles a K67, so both microphones have similarities, too. After the filters in the U67 have been lifted, they will be pretty close actually, although I expect the treble peak in the Sony to be centered somewhat higher. In any case, the contrast between the two will basically be gone, so you'll have a less versatile combo.
Is the Sony yours or do you have easy access to it?
In76d wrote about the E80F. If it fits on the IOaudio PCB, too, you could give that a try. From what I've heard it's a little more open sounding, but a little leaner on the low mids. The proof is in the pudding
Talking about pudding, this is a DIY platform, so yeah, why not give the filter removal operation a try? You can always redo it, can't you?
Do keep us posted, please!
BTW, in the old days in the big studio's engineers liked to use a Pultec on the U67
if they needed more treble. The U67 takes (good) EQ like a dream. This is what it sets it apart from others. And it was designed this way. (!)
Genuine Pultecs are very expensive. But you could build your own via this here forum.
And Warm Audio came out with a ready made clone that is actually affordable.
But there are other types, too, of course. Have you tried lifting the highs with a good equalizer?
