Hello, I’m beginning my personal little crusade in the Ribbon Mic arena.

To start, I’ve created an Instructable, to upgrade an MXL 990 condenser mic with a ribbon element from

I created some 3D printed parts to hold the ribbon element and transformer.

But I think one of the key things is I also created a 3D printed ribbon alignment jig. It makes it really easy to replace and re-ribbon the element.

I’ve already gotten a ribbon alignment jig designed for the MXL R80 and MXL R144 mics. I’ve re-ribboned the R144, and replaced the transformer, and it sounds a billion times better. I have re-ribboned the R80, and redesigned the element placement and holder (to make it symmetrical) along with a new transformer as well. Very pleased with that too. I will post these updates to Instructable and Thingiverse shortly

In the meantime, please check out my instructable, and parts on thingiverse.
