Modification Options for the MK-319:
electronics mod kit contains all the components listed below. Detailed
step by step instructions, like those provided with the 012 kit, are
not included with the 319 kits. Pictures showing all the part placement
changes come from
modifications to the body and capsule basket. Just hold a 319
hand and tap the basket screen with your finger. You will hear it
"ring" and feel the vibration in your hand. As part of the
modification, damping of the body, the basket supports, and
isolation of the capsule, virtually eliminate this. One layer
capsule basket screening is removed.This opens up the basket,
minimizing sonic reflections and
reduces some "ringing". Normally the capsule diaphragm
discs are removed. This is optional, removing them provides a warmer
more rolled-off top end, they are intended to trap the high-freq and
extend range. I prefer them removed.
components are upgraded to quality parts. Polypropylene capacitors are
used in the direct signal path. All the components on the PC board
are replaced except for 5 resistors and the
The improvements in the electronics increase the high and low end
response, flatten the response, increase detail, warmth, and provide a
lower noise level.
The low cut and attenuation switch daughter board is removed. The switches will remain, but will not function. long wires going to the daughter board directly carry the capsule signal, this causes loss in sonic detail. The removed daughter board is returned to you, as are all removed parts and components (removed screen is not returned).
The body is damped
One layer of head basket screening is removed
Damping material is applied to the inside of the basket supporting posts
The capsule is isolated from Vibration
The PC Board is isolated from Vibration
The capsule diaphragm resonator discs are removed
Damping material is added at the base of the capsule
All critical electronic components are upgraded to quality parts
The low cut and attenuation switch daughter board is removed

difference you can Hear!
"I just wanted to thank you again for mod'ing my 319. I was able to do more recording with the mic today and I have to say that I really love it! Before I had you work on it, I would take it out, give it a try on some tracks, and end up putting it back in the drawer and re-recording the tracks with a different mic. You've made this mic into one seriously great mic. Where the sound was muddy and distant even when practically eating the mic, it's now clear, yet with that nice, warm sound that the 319 has become known for. If this is what you call a significant difference, I can't wait to hear what you call a dramatic difference when I send you my 012's."
finished the mod
on the weekend. This was my first electronics project in a
long time, so it isn't pretty, but the results are amazing.
thing I notice most is the difference on sibilant sounds. The
combination of physical and electronic changes removes the "esh"ing
that I notice on most mics below several hundred to even a thousand
dollars. I used to have to put in de-essing plug ins to
compensate. Now I can just enjoy the sonic characteristics of
recording. There are other qualities that I'm noticing too - changes in
the frequency range and the like - that I'm still getting my ears used
to. They're hard to describe, but make the recording far more
pleasing to listen to. Thanks for all of your help."
wanted to give
you an update on the four 319's you help mod for me. To refresh your
memory, I did the physical mods and you finished them off with the
electronic mods. Anyway, I have used them for multiple purposes, two
point stereo, guitar/bass cabs, piano, drum OH's, and more and they
have performed very nicely. I have used them with some big dogs, i.e,
Schoeps ccm4's, Neumann SM69, 103's 184's, AGK 460's Royer ribbons,
etc, and they have fit right in. I can't believe that for so little
money I've ended up with such a great mic. I bought four of them new
for $79.00 each and after the mod I've got $200 into each mic. They
certainly outperform this price point and much higher point. My next
step is to make a damping corset, made out of leather, to wrap around
the outside of each mic. I think this will really damp any resonance
problems that remain and should look great, too. Finally, the proof is
in the pudding. Almost all my recordings have at least two 319's in use
and my clientele have thoroughly enjoyed their recording and have
showered me with praise."

my mic and I love it. I had to do some experimenting at first as to how
to position it. Before, I got a better sound straight up. Now I get a
better sound having it hang down. The big thing I notice is the highs
are super crisp and don't splatter when I throw a little EQ in post.
The base is nice and tight and if I really get right on the mic, the
(in your face) sound is probably the best I've ever heard. I take it
that the spare parts are what you took out of it? Thanks again Bill. It
really sounds awesome. I can't wait to show my friends who also have
You recently did a mod to my MK319. You mentioned to me that the mic
would get better as time went on. Let me tell you Bill, at this point
in time I could not be happier. I've had a lot of compliments from
people I do steady VO work for on how my spots are sounding. Again,
thank you Bill for a great job."
