From the seller
I’m selling my Michael Joly 990 Hulk with the MJE-K47 3 micron gold sputtered capsule
This mic has been gently used in a professional studio environment and is in great condition physically, sonically and electronically. This microphone has a wonderful clear top end which isn’t harsh or overly sibilant and with nice midrange body which sounds similar to a U87ai and to my ears a smoother top end. I’ve had 3 Neumann 87s over the years and this mic competes well from most aspects and is considerably less expensive. It has a single cardioid pattern which should cover most recording applications. It is a wonderful sounding microphone on lead vocals and has just a hint of air at the top. The 3 micron capsule allows the mic to capture subtle nuances that are missed with less sensitive microphones.
This microphone Single Layer Headbasket Mod -
Like all Michael Joly Engineering microphone upgrades, the MJE-K47 mod suite for the MXL 990 starts with Joly’s signature single layer headbasket. A completely new headbasket replaces the stock, multi-layer basket to dramatically increase open area to reduce internal reflections and coloration. 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 – plus, is within reach. The 3 micron MJE-K47 capsule was designed to track and sound like an actual Neumann K47 capsule through the important midrange then provide an extra touch of “air” at the very top end. You’ll hear the classic mid-focused vocal punch of the K47 design with just a bit of modern sheen on top. When this frequency response extension is translated to the time domain, you'll hear faster and more accurate transient response as well. Faster, more accurate transient response means greater detail and resolution – without the need for a high frequency EQ boost and its accompanying phase shift. Also, by incorporating the more sensitive MJE-K47 large diaphragm capsule, this mic's S/N ratio improves as well as well giving you an extremely low self noise.
Note extended high frequency "air" provided by the 3 micron diaphragm MJE-K47 capsule
Premium Electronics Modification -
The circuit used in the MXL 990 is a close approximation of a classic Schoeps transformerless design. But to save on production costs in the stock mics, inexpensive poor-sounding ceramic and under-sized capacitors are used in critical signal path locations. The MJE-K47 Mod Suite attacks these compromises by substituting components and topology pioneered in my field proven (over 6500 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.
Capsule: Upgraded to a custom 3-micron / 34mm-style MJE-K47 large-diaphragm capsule designed to track the Neumann K47 midrange punch with added top-end air. [1, 2]
Electronics: Upgraded premium electronic components and circuit topology replacing stock ceramic and under-sized capacitors in a Schoeps-style transformerless FET circuit.
Headbasket: Custom single-layer headbasket replacement to eliminate internal acoustic reflections and reduce coloration compared to the stock multi-layer MXL grille. [1]
Polar Pattern: Fixed Cardioid. [1]
Circuit Type: Transformerless FET solid-state preamp
