Update. Here is the telephone mic. I had to replace the transformer and I mounted everything on a pc board all internal to the head. Sounds better than before and it’s more solid construction. It has a high gain and looks all Steam punk. Runs on phantom power .
Perfect for thet “Telephone” Sound or for that bluzy grunge harmonica sound.
I have a bunch more of these Carbon Elements and a few more transformers. I think I’ll build them up and sell them on Craigslist.
