I'm new to DIYaudio, so I hope I'm posting on the right place.
My omni-directional Modmic quit working and I was hoping to repair it by simply matching the mic capsule inside. However, opening it up revealed a mic capsule with absolutely no markings, and I have been unable to find any details on the Modmic to allow comparison for replacement.
I haven't checked the mute switch to see if it is the failure point yet since I will likely destroy the plastic in attempting to open it. I wanted to replace the capsule first subs it would be the easiest fix.
Any recommendations on what I should look for, or where I should look for a replacement capsule?
Thanks,
Tony

Tony, welcome to the forum.
From what I found, the capsule should measure 2.2 Ohm. Checking that is a starting point.

If it appears to be broken, you could probably find a replacement.
It's a electred capsule, not a condenser one so this will narrow your search:

Always buy from a reputable source.
Since the mic is now open, you can easily measure if the mute switch works or if the cable
is broken. If it's not the capsule, I'd recommend buying a new mic. They are relatively cheap.
Hope this helps.

I would suspect the mute switch before the mic capsule and before either the lead is most common , that being said check out Primomic .com for capsules .
I would guess that that 2.2 ohm is a typo for 2.2 kohm and that the microphone capsule is an ordinary two-pin omnidirectional electret microphone capsule with built-in JFET common-source stage.
There are many such electret microphone capsules on the market. They vary quite a bit in sensitivity and equivalent acoustic noise level, but they are all meant to be supplied from a clean supply of approximately 3 V (anything from 2 V to 10 V will do) via a 2.2 kohm resistor. As the common-source stage is fairly high-ohmic, the 2.2 kohm resistor determines the impedance.
