The Fostex M33rp is possibly the rarest mic from Fostex's line of "Regular Phase" microphones. It's the only omnidirectional mic from the line, and we've never seen another like it. The hot orange engravings make it even more exotic. This mic is in good working order and comes with a new sturdy Shure clip.
The microphones from Fostex's line of "Regular Phase" microphones from the 80's and 90's are often referred to as "Printed Ribbon" microphones (and eventually even Fostex started using that term), and this is because they have a proprietary capsule design that has the coil printed, or etched, into the diaphragm. This makes the microphone neither a dynamic nor a ribbon by design, but some kind of a hybrid which has the same accurate phase response and pistonic movement of a ribbon, with the durability and SPL handling of a dynamic.
