MJE Hulk 990
With signature single layer headbasket design and 3 micron MJE-K47 capsule
Buy a new MJE Hulk 990 for only $429 complete with shock mount and case. 
Many folks need one great mic to record vocals, acoustic guitar and percussion. The MJE Hulk 990 is that mic. The 3 micron diaphragm MJE-K47 capsule offers classic “Neumann-esque” sound up to 10kHz then keeps on going to deliver a touch of sparkle in the “air” band.
Record an acoustic guitar track, then reposition for male or female vocals. Classic LDC sound and vibe on both takes. Move it into position as part of a Glyn Johns-style three mic set up for drum overdubs – hear punch, clarity and shimmer with no top end harshness. Hear it vs. the current industry-standard Neumann U 87ai. 
Hear clear and open sound - the MJE Hulk 990 features a single layer headbasket (the classic AKG C12 was a single layer headbasket mic) to avoid the coloration effects heard with multiple layer headbasket mics. 
New Michael Joly Engineering MJE-384
A complete set of world-class small diaphragm mics – only $699. 
Whether it’s a pre-production mic shoot out test or hit-bound recording session, the MJE-384 matched stereo pair delivers the sound you need at a price you can afford. In a direct comparison on drum overheads, the MJE-384 has been chosen over Schoeps CMC6 / MK4 by the session drummer. In a direct comparison on acoustic guitar, the MJE-384 has been preferred by session guitarists over the KM 184. Listen for yourself – open, natural, relaxed, true-to-life plus a touch of top end air and sparkle. Write to me to learn how the MJE-384 compares to my well-known modified Oktava MK-012. 

MJE-LR44 Ribbon Microphone - the Coles 4038 alternative
New Michael Joly Engineering MJE-LR44
Long Ribbon Microphone
Need a ribbon mic with better-than-classic sound? – the MJE-LR44 only $599. 
Hear the MJE-LR44 vs. the RCA 44 and Coles 4038 on drums, piano, guitar, male and female vocals then judge for yourself. The MJE-LR44 long ribbon mic is more open, more transparent, more accurate and resolves transients better. Quite a claim. Listen for yourself, you’ll believe. Questions? Just write to me. 

Welcome note from Michael Joly -
You need classic microphone sound, right? Hear new modified microphones, after-market microphone modification services for your mics (we do the work in our shop - no DIY risk!) and my own Michael Joly Engineering mics vs. the classics. I believe you’ll find these modified microphones and my MJE mics to be affordable alternatives to the Neumann U 47, U 67, U 87, KM 84, KM 184, Coles 4038, RCA 44 and Schoeps CMC6.
Whether you're looking for the right vocal microphone (a U 87 alternative perhaps?), a great acoustic guitar mic (a KM 84 alternative?), guitar cab or drum overhead mics you'll find them all here - with sound samples vs. some classic microphones.
BTW - Here's a new article I've posted: LDC Mic Headbaskets - A Necessary Evil. 

- Questions and Answers from my email -

Question: Why should I have my mic modified? Why should I buy a new modified mic?

Short Answer: Better Sound and Better Value with MJE mod’d mics. Here are the details …. 

… Even though I’ve offered professional microphone modifications for almost 10 years (and we get busier year-after-year), I still see these questions on gear forums. Here are a few reasons why over 10,000 MJE / OktavaMod clients have chosen to buy a new mod’d mic or have their own mic modified.

Many folks want better sound than what they’re getting from a mic they currently own. For example, lots of people purchased an MXL 910, v250 or 990 on a “Stupid Deal of the Day” for $49.99 or $69.00. These are all basically the same small diaphragm capsule / transformer-less circuit mic. And they all have the same thin, excessively bright and sibilant sound that just cannot cut world class vocal tracks. Its worth saying this again - these are all small diaphragm mics in a side-address form - not large diaphragm vocal mics. 

Michael Joly Engineering can transform these mics into world-class performers that can go head-to-head with a Neumann U 87 - for just $329. Listen for yourself:

A recordist cannot buy a new, large diaphragm condenser mic that comes close delivering the U 87 sound (in cardioid) for $329. So rather than throw away the initial investment AND have to spend significantly more than $329 to get U 87-like sound, many folks prefer to have me modify their existing microphone. Initial investment saved, door stop use avoided, and U 87-like sound delivered for just $329. 

Other folks are looking to start, or grow, their mic locker by purchasing a new microphone. The MJE Hulk 990 is our most popular mic because it sounds so much like the U 87ai for only $429 - complete with shock mount and case. Again, listen for yourself:

The Hulk 990 features an exclusive, single-layer / angled head basket that offers clear and open sound without the internal head basket reflection coloration that accompanies two and three-layer head basket designs; a 3 micron MJE-K47 capsule built to proprietary specs to deliver sibilance-free, “Neumann-esque” sound; and a signature MJE Premium Electronics package for maximum resolution, low distortion and wide, flat frequency response. 

Yes, there are other mics in the $400 category. But there is only one MJE Hulk 990. Only the MJE Hulk 990 offers an MJE signature single-layer head basket, capsule and electronic features that allow it to go up against a $3600 U 87ai - and win. Oh, and folks can talk with me directly, the Hulk 990 designer, if they wish to get help choosing a mic. Last I checked, Georg Neumann was no longer answering FB messages or email ; )

Why buy a mod’d mic? 

Well … with an MJE mod’d mic you get better sound, dollar-for-dollar spent vs anything else - and a personal shopping experience that is second to none. Listen for yourself, then contact me - you’ll believe.

Ps - Whether you're interested in a new mic or a microphone modification service performed in our shop your purchase is RISK-FREE. Just write and I'll tell you exaclty what that means in your particular case. Best, Michael
