Ribbon Mic Resources

Inspired by a discussion with Gord Wait, I've assembled some resources about Ribbon Microphones in case anyone else is interested.

A brief introduction to ribbon mikes by Sarah Jones on the EQ Magazine site- http://www.eqmag.com/article/www.eqmag.com/article/122029
An in depth article (PDF) by Streicher & Dooley about how bi-directional mikes work including some great diagrams of ribbon motors- http://www.ribbonmics.com/pdf/Bidirectional%20Microphones.pdf

Matt McGlynn, Ryan Canestro and I conducted comparison tests of many ribbon mikes:
