new technology creates the
most natural acoustic sound ever.
Complete, modular systems
for every guitar and every sound.
EMG has invented a totally new pickup system for acoustic guitars that
has the most natural sound that you've ever heard. Since the 1960's, acoustic
guitar pickups have used ceramic crystals which have two inherent drawbacks.
First, they have an annoying audible resonance which results in a harsh
tone. Second, the output impedance is too high for normal amplifiers,
compromising the natural tone.
In the AT93 and
AT125 pickups, EMG mounts a durable, thin piezo
film under the bridge saddle. Free of crystal resonances, the pickup
is so sensitive you can literally hear the difference between plastic
or bone bridges! The installation is clean and invisible, and, because
the film runs the entire length of the bridge, you get great results with
custom string spacing, 12-string, or even nylon-string guitars.
The APA-2 preamp
was designed to complement these pickups. It mounts completely and unobtrusively
inside the guitar body including a battery holder. If you've ever heard
a piezo pickup that had a thin, scratchy, bassless sound you've heard
the negative effect of improper impedance matching. With the APA-2, you
will hear rich, full, natural sound. Its 2000 ohm output impedance and
adjustable gain are a perfect match for any amp or mixer and delivers
great natural tone.
If you need to tweak your sound, you
can install the AEQ-3 3-band equalization system
which features independent treble, mid, and bass controls right on your
Our newest model, the EMG-ACS,
gives you great tone with minimal mods to the instrument. This compact
pickup fits in the sound hole and features EMG's Quick Connect cable for
quick and easy removal. The ACS includes a built-in internal preamp specially
tuned for a beautiful transient acoustic tone, adjustable polepieces,
and a fingertip volume control, mounted on the pickup.
|EMG's piezo film pickup captures the
true natural sound of your guitar with a purity unmatched by any other
acoustic pickup. Located under the bridge saddle, the EMG-AT93
captures rich sound of the guitar while reducing the top noise endemic
to top-mounted pickups.
All our under-saddle pickups
use EMG's "bimorph" piezo film design for which EMG has been granted
two U.S. Patents (Nos. 5123325 and 5204487). This unique design combines
two piezo film layers using much less adhesive for purer sound while
increasing the pickup output level.
The entire installation is invisible
(including the preamp, which mounts internally in the guitar body)
so there are no wires or obstructions on the exterior of the guitar.
No adhesives or damping materials are used in the installation of
the pickup to prevent resonances as well as to preserve the acoustic
sound of the guitar.
The AT93 pickup element is 3/32"
(0.93"/2.3mm) which is perfect for most Martins. The AT93L element
is the same width but comes in a two-part design for use on guitars
that have a split bridge saddle.
| The EMG-AT125 is
the same great design as the AT93, but the pickup element is 1/8" (.125"/3.1mm)
for better fit on guitars with a slightly wider bridge saddle. Choose
the AT125 whenever the saddle width is greater than .115" (2.9mm). If
it's less, use the AT93 instead.
|The EMG-APA-2 Acoustic Preamp
has been designed with the needs of acoustic players in mind and is
the perfect complement the AT93 and AT125 pickups. It combines a miniature,
low-current draw preamp and a 9 volt battery holder in a single package
that attaches to your guitar's front block (at the internal joint between
body and neck) with two screws.
The natural output impedance of a
film or crystal pickup element is much higher than that of a traditional
magnetic pickup. If you plug the output of a piezo directly into a
conventional amp input, the impedance mismatch causes a loss of signal
output along with a huge loss of bass - you get a brittle and unpleasant
sound (sound familiar?). The APA-2 features a very high input impedance
(2 Megohm) to allow the piezo pickup to deliver powerful, natural
sound across the entire frequency range.
In addition to the piezo input, the
APA-2 also includes an input for our ACS magnetic
soundhole pickup which gives you the best of both pickup worlds. Since
you might require different EQ settings for each pickup, we include
our exclusive stereo UltraJak end pin jack
which delivers each pickup's output separately. The UltraJak also
includes a switch that disconnects the battery when unplugged to extend
battery life. You can assign the pickups to the ring and tip contacts
for complete customizability.
Our low-current circuitry should
give you 2900 hours of battery life between changes. When you do need
to change the 9V battery, our specially-designed battery clip makes
it easy to change the battery through the soundhole. There's also
a convenient trimpot that allows you to vary the output level to match
the device that you're connecting to.
All EMG Acoustic products are available individually
or in pre-packaged systems. Kits include either the AT93, AT93L, or AT125
pickup, the APA-1 or AEQ-EQ-3 preamp, the EMG UltraJak,
a custom strap endpin that incorporates our 360° full-contact output
jack and battery switch, and any other parts required to complete the installation.
Due to the complexities of working inside acoustic guitars, professional
installation is recommended. See the Price List for a full listing of all
|If you need more control over the tone
of your instrument, consider the EMG-AEQ-3 On Board Equalization
System for acoustic guitars. Mountable in the top shoulder
of your guitar, it feature two concentric stack pots with bass+treble
and volume+midrange combinations.
The tone controls each have a wide
12db boost and cut range. Even better, the treble EQ center frequency
can be selected via a mini-DIP switch to give you an even wider range
of control (8.5/10/13.5/15.5KHz selectable).
The AEQ-3 also includes a battery
clip that mounts inside via the neck block for easy access and our
new UltraJak to complete the
installation. The AEQ-3 is the perfect match for the AT93 or AT125
acoustic pickups but works great with ANY piezo pickup system.
|The EMG-ACS Acoustic Sound
Hole Pickup gives you great amplified acoustic sound with a
simpler, less involved installation procedure. Using a specially designed
mounting adapter, the pickup perches in the sound hole. Six individual
polepieces allow you to simply modify the string balance. The ACS features
EMG's Quick Connect cable so it's a breeze to remove and reconnect the
pickup. An internal preamp, optimized for acoustic sounds, is mounted
inside the pickup and a fingertip volume control is conveniently located
on the edge of the pickup.
| The UltraJak is the
ultimate output jack for acoustic guitar. Designed and manufactured
by EMG, it features a number of revolutionary features that improve
both functionality and reliability. The most important addition is our
exclusive 360° spring contact system, used on each
of the jack terminals. A conventional jack's contacts are flat, touching
your cord's plug at a single point. As the jack and contacts wear, you'll
get intermittent contact that makes those very loud popping noises when
you jiggle the cord. Even when it's not worn, the weight of the plug
and cord sticking straight out of the endpin causes uneven pressure
on the different contacts - again leading to pops and noise. The UltraJak's
custom contacts surround the plug terminals so you get a strong mechanical
connection with no noise, regardless of the orientation of the jack.
The unique design of the UltraJak
has been awarded US Patent No. 5809136.
For more sophisticated setups, the
UltraJak features true stereo output (tip/ring/sleeve)
to support either a stereo pickup or letting you run both a magnetic
soundhole pickup and a piezo bridge pickup
with a single cord! Nobody else has this feature in a conventional
Finally, there's a separate
battery switch that preserves battery life while allowing
It's all here in a tiny package that
combines the best features with the bulletproof reliability that you
expect from EMG.
|Life can be complicated and difficult.
Your guitar's pickup system doesn't have to be. We created
the AmpJak to sound and work great with minimal modifications
to your guitar.
It's simple and straightforward -
the system consists of the same, high-quality piezo film pickups as
our AT93 or AT125 models
combined with a clean and accurate preamp mounted in a special housing
based on our proprietary UltraJak endpin plug.
With the electronics mounted on the jack, you don't need to drill
holes to mount an amplifier module, and no exterior drilling is required
The output level is set to an optimal
level at the factory, but there's also a trimpot that lets you adjust
the level for your specific needs. The AmpJak is
available in kits with either the AT93 or AT125 pickup depending on
the bridge width of your guitar.
If you need to mix piezo and magnetic
pickups on the same guitar or require a sophisticated EQ system, our
other models are more appropriate. But if you're looking for great
sound while maintaining the stock appearance of your guitar, you can't
beat the AmpJak.
