I have a stash of handsets that look just like this:
I've been itching to do some soldering and such and thought I'd share the wealth of cheap Japanese phone handset microphone fun. They all have carbon mics for that sweet AM sound.
I can wire these to have just about any output you'd want, I imagine an XLR might be overkill, but if that's what you want, I'm down. I also can just give it a pigtail with a 1/4, which is the easy way to go.
I can also mod these to work as a Skype handset, mobile phone handset. I think you get the picture.
This isn't super difficult so I'm not trying to make money really, I think something in the ballpark of $10+ shipping or $15 shipped USA domestic sounds fair, but I'm down to trade or negotiate.
