Single Layer Headbasket Mod -

Like all Michael Joly Engineering microphones, the MJE FatBoy starts with my signature single layer headbasket conversion. You’ll hear clearer, less “boxy” and more detailed sound with more accurate transient response – hallmarks of the classic AKG C12 – itself a single layer headbasket design.

MJE-K47 Capsule Upgrade -

Classic sound is within reach. The 6 micron MJE-K47 capsule was designed to track an actual Neumann K47 capsule across its entire operating range. You’ll hear the classic mid-focused vocal punch of the K47 design with a sibilance-free top end. Upgrading from the stock SDC capsule to the more sensitive MJE-K47 large diaphragm capsule improves this mic's S/N ratio as well.

Premium Electronics Modification -

The circuit used in the stock MXL 910 (the donor mic for the MJE FatBoy) is an implementation of a classic Schoeps transformerless design. But to save on production costs the MXL 910 makes extensive use of inexpensive surface-mount parts. The MJE-K47 Discrete Premium Electronics suite attacks this compromise by substituting higher quality, better-sounding components and topology pioneered in my field proven (over 8700 units in use) Premium Electronics modification. These component upgrades improve bass response and reduce graininess and mid-to-high frequency distortion while providing a smoother top end sound.
