Product Description

Includes original shock mount, PSU, cable, and four hot-swappable heads (C12, U47, ELA-M 251, U67).


The Korby Audio Technologies KAT microphone is an interchangeable capsule system. The first of its kind to incorporate the matrix of a system that will accept both the Neumann style of center-contact and the AKG floating diaphragm. A system to be used with a single amplifier, designed so that a palette of microphones could be utilized without the necessity of having an abundance of microphones at your disposal. However, practicality was not the driving force of this design; we believe you will be impressed with the beautiful tones these capsules will produce.


“I individually build and tune each capsule one at a time and let my ears finish the job from where test equipment leaves off. Try them. They Sing!”

The Korby Convertible is the finest new tube microphone available. A revolutionary, interchangeable head design, available with a 251, C12, U67 and U47 head assemblies. The heads are hot-swappable and can be removed without the use of tools in session. They feature hand made, ear-tuned capsules, NOT Chinese capsules like most of the boutique mics seen in Mix magazine!

Tracy is truly the finest mic craftsman/capsule builder in the world and the last of a dying breed. There are a few self-proclaimed mic craftsmen, but do not be fooled. Tracy Korby takes great pride in his work and backs it up every step of the way! The C12 and U67 are multi-pattern, while the U47 and 251 are cardioid only for optimum fullness (multi-pattern available for these upon request). Beautifully hand crafted by Korby Audio Technologies.
