Just a simple question : do i need à spécial soldering Iron for such à small cap or à regular one is good?

That sort of depends on how skilled you are, with whatever soldering iron you have :)

That cap looks like a 1206 package, so it should be easily removable even with a soldering gun ;)

A few years ago, i had to troubleshoot a TV processor board, which involved removing and resoldering 0805 and 0603 sized ferrite beads in series with some supplies to one chip. I did that with my ancient soldering gun, with the tip being a shaped loop of 1mm copper wire ;D

Not much experience here, but you probably don't want too narrow a tip. I've just been practicing soldering on a cheap BM-700 mic since I don't mind if that gets trashed, but I find that too narrow a tip might make it difficult. I'm just using one of those cheap $20-something soldering kits from Amazon though.

Has anyone else tried this modification?

Why AKG did this is beyond me. The C3000 mics have a somewhat bad reputation because of this. Without that capacitor they'd be much better mics and people would actually want to use them. If they were 3 pattern omni/cardioid/figure 8 I'd be all over them.

No but it's not really an uncommon mod. Usually you replace a capacitor to improve the negative feedback to make a K67 caspule work properly, not remove a capacitor that injects a ton of signal, but it's kind of the same idea. You just won't be adding another capacitor.

First, I want to apologize for my bad English.
I do not know anything about electronics and I would not like to damage the microphone, but I have a C3000b and this modification seems easy.
So, is this a usual and safe modification? Will this modification significantly improve the microphone response? Or is it a waste of time?

Do I just need to remove the c303? I do not have to do anything else?

There are measurements i have taken and posted here. So you can easilg draw the conclusion what the mod does. It is a boost in the circuit no one really needs.

Yes, you should just remove the capacitor. You do this at your own risk, and you have to decide for your self if it is worth it, just like with any mod. Technicaly, nothing wrong about removing that cap, it just makes the circuit flat.

Hello KingKorg, thanks for responding so fast.

If I understood correctly, in summary, this modification brings the c3000b to 414, when it works in cardioid polarity, is not it?

Please, don´t be angry with me, I don´t doubt your knowledge, I am Spanish and I have doubts about my English  :-[

Finally, I understand that it is my risk to modify the microphone. I have a friend who is an electronic technician and he will help me. Thank you for your concern.

Not mad of course, i hope i didnt give you that impression.

Well, yes that is true about the response. However if you dont like the mod, you can always put back the capacitor. It is a fairly big one.

I thought that the capacitor could not recover, it is good to know that it is possible.

I think I'll talk to my electronic friend to start working.

If possible, I will try to contribute conclusions to the forum

thank you very much again
