gives you Active Equalization right
at your fingertips.
Turn night into day with the
turn of a knob - right on your guitar!
Whether you play guitar or bass, EMG's full line of EQ and accessory circuits
give you total control over your sound without taking your hands off of
your instrument. Moving beyond the passive treble cut tone control of
conventional instruments, EMG EQ systems include active treble and bass
controls that can both boost or cut treble and bass up to 12dB. In addition,
the guitar tone circuits can reshape the midrange response to get that
"scooped" metal tone or create a humbucker-like sound from a single-coil
pickup. Bass systems start with add-on active bass and treble controls
and range upward to full electronics systems that include continuously-variable
parametric midrange controls, volumes, and even pickup balance controls.
Each system comes completely pre-wired
for ease of installation and greater reliability. The compact surface-mount
design yields a smaller electronics package - not only an easier fit in
tight control compartments, but reductions in power consumption as well
(1250 hours for many models!). To further save space, all EMG EQ systems
(even multiples on the same instrument) can share the same 9V battery
power source as the pickups. Most of the systems are available with either
separate control pots or concentric pots mounted on the same shaft. Concentric
controls allow you to replace a passive treble cut control with an active
bass and treble control - no need to drill additional control holes.
All EMG accessory kits come prewired
with complete instructions showing basic and optional setups. Most Bass
setups (except the EXB) include knobs; all other systems come with split
shaft pots appropriate for use with standard Fender- or Gibson-type knobs.
If you are ordering a custom EMG pickup set from the factory, you can
specify your choice of accessories to be integrated into the assembly
at the factory.
Accessories for Guitar
Although any EMG EQ or Accessory circuit
can be used on guitar or bass, these units have been designed with the guitar
|The EMG-SPC Presence Control®,
also known as "The Fat Control"(tm), is an active midrange boost circuit.
Mounted on a potentiometer, the SPC gives up to 6dB boost at 1300Hz
while rolling off the highs. When used with an EMG-S or SA single-coil
pickup, you can recreate a humbucking tone without routing. With an
EMG humbucker, you'll get a broadened mid-peak and a rounder tone. When
turned all the way down (counter-clockwise), the SPC yields flat response.
|The EMG-RPC Resonant Peak Control®,
selectively boosts the high frequency range up to 6dB at 4000Hz while
reducing the mids and lows. At it's lowest setting, there's no change
to the natural tone of the guitar. As you increase the value of it's
single knob, your sound is accented similarly to a single-coil pickup's
response. The RPC circuit is mounted directly to the back of it's control
potentiometer and attaches easily to your existing setup.
|The single knob EMG-EXG Guitar
Expander® simultanteously boosts the highs (around 4000Hz)
and the lows (centered at 40Hz) while dipping the midrange (1000Hz).
The net effect is is a solid, clean low end, sharp attack and improved
clarity from the reduced mids. Picking and rhythm chording come through
with an acoustic-like quality which is fully adjustable from flat to
|The EMG-DMSK Dual-Mode Switch
Kit® allows you to simulate a single-coil sound with any
EMG humbucking pickup. It utilizes a capacitor in series with the pickup
output to naturally roll-off the low frequencies. For even greater flexibility,
the kit includes three optional capacitors that allow you to tailor
the roll-off to your tastes. Activated with a single mini-toggle switch,
the DMSK can be used much like a humbucking coil-tap switch without
the hum associated with traditional coil-splitting. The DMSK also preserves
the low-impedance output of the pickup.
|This fully active phase reversal circuit
is for use with any multi-pickup instrument. Mounted on a single mini-toggle
switch which activates it, the EMG-Pi2 Phase Reversing Switch®
produces a true 180° phase shift. When used on a guitar with two
or more pickups, you'll hear a distinct change in tone as phase switch
changes the cancellation and reinforcement frequencies in the output
blend. The Pi2's active phase reversal maintains the full quietness
and low-impedence output of your EMGs. You use this circuit on either
pickup of a two-pickup configuration or on the middle pickup of a three-pickup

|Mounted on the back of a mini-toggle
switch, the EMG-PA2 Preamp Booster® give you
a 0-20dB boost without changing your tone. The boost level is preset
using a trimpot on the circuit board. You can quickly kick up your
levels for a lead or drive a long cord without losing high frequencies.
You can wire the PA2 on any single pickup of a multi-pickup setup.
You can use the PA2 with guitar
or bass. It can also be used with non-EMG pickups for low-impedence
|The EMG-VMC Variable Midrange
Control delivers an incredible level of control over the critical
midrange section of your sound. The VMC is a sweepable equalization
circuit (also known as a parametric
or quasi-parametric EQ). It's a special tone control that not only lets
you boost or cut a specific part of the tonal spectrum, but gives you
the ability to adjust the center frequency
across a wide range to tailor your tone precisely. Provided on a stacked
potentiometer that allows two knobs through a single hole in your instrument,
you get a big 12dB of boost or cut wherever you focus the EQ (continuously
sweepable from 300-3000Hz).
You can add a VMC to the BTC
or BTS to upgrade your EQ to a three-band
bass EQ system.
Accessories for Bass
Although any EMG EQ or Accessory circuit
can be used on guitar or bass, these units are tuned for use with electric
|Similar in concept to the EMG-EXG,
the EMG-EXB Bass Expander ® lifts the bass and
treble response while cutting the midrange. The EXB's center frequencies
have been focused for the bass with a higher treble frequency (1600Hz
vs. 1300Hz) that gives added definition to slapping or an aggressive
pick attack. In addition, more boost (10db) is available. The EXB's
small circuit board is mounted directly to the back of it's control
potentiometer, and will fit easily in any normal control compartment.
|The EMG-BTC and BTS Active
Bass and Treble Controls can totally change the sound of your
bass. Two completely independent controls allow you to tailor your sound
right at your instrument. Unlike a traditional passive tone control
which can only cut treble frequencies, the BT controls can independently
boost or cut both bass and treble frequencies up to 12dB. In addition,
a set of DIP switches mounted on the main circuit board allow you to
select among 4 widely different center frequencies ranging from the
high midrange to treble region (2100, 3500, 4500, and 7000Hz). The bandwidth
of each setting is also tuned to allow the most musical voicings. For
convenience, both the bass and treble controls include detents that
allow you to easily dial in flat EQ response by touch.
The circuit is available in different
versions to fit your bass and control preferences. The BTS
Control places the bass and treble controls on separate knobs.
The BTC Control stacks the two controls on a concentric
pot. This allows you to install the BTC in place of an existing passive
control without drilling additional holes in the instrument. Both
the BTS and BTC units can be used with passive pickups as well as
If you are ready to go to a complete
EMG active setup, you can also select the BTS or
BTC Systems. For use only with EMG pickups, the Systems
combine the BTS or BTC controls with Master Volume and Pickup Balance
controls. The balance control allows you to blend the sounds of the
bridge and neck pickups without the loss of treble or bass that can
occur with standard pickup volume controls. It also includes a detent
at the equal blend position.
All the BT family circuits come prewired
for easy installation and includes all required hardware including
a matched set of black knobs. The systems are set up for 9V operation
off a single battery (including pickups) but can be optionally operated
with 18V for additional clean headroom.
|For the maximum control over your sound,
EMG offers the EMG-BQ Three Band EQ Family. In addition
to all the features of the BT circuits, the BQ
add the VMC parametric midrange control. Available
with bass and treble controls on separate or concentric knobs, the BQC
and BQS Controls are compatible with conventional pickups. If you prefer
a complete prewired system with master volume and pickup balance controls,
you can select the BQC or BQS Systems.
Installation is straightforward using
EMG's detailed instructions. The only soldering required for prewired
systems is the attachment of the pickup leads.
