EMG-ABQ PRE-AMP (Frequency Selection)
The 3-position dip switch allows you to change the resonant frequency at the input to the pre-amp.
The frequencies will be different if you use a passive pickup other than the ALX.
If you use an Active EMG Pickup the switches will not make any change.

Installation notes: (Signature Model)
The EMG-ALX set includes either an ALX Pickup or the F-ALX (Floyd Rose Spacing) and the ABQ Preamp. The ALX/F-ALX Pickups are slightly overwound
humbucking pickups that feature a ceramic magnet for clarity. The ABQ Pre-amp has a Push-Pull Pot with an adjustable boost in the down position.
As an additonal feature the input of the ABQ Pre-amp has a 3-position dip switch that allows the resonance of the pickup to be altered to a variety
of fixed frequencies. There are two different instruction sets for the ALX Set. This set of instructions is for the Alexi Laiho Signature Model.
The alternate set of instructions is for guitars that are wired differently than the Signature Model or, that may have more than one pickup.

SPECIAL NOTE: The Red Wire of the HZ Pickup Cable is NOT for battery power, it is a coil wire.

Remove the existing pickup, volume control, output jack, and pre-amp on/off switch if
there is one. The switch will not be used again because the installation now includes a
push-pull pot for the preamp on/off function.
The installation starts by installing the wires for the output jack.
Refer to Diagram #1
The installation starts somewhat backwards. Instead of installing the pickup first,
the output jack is installed.
It is first necessary to “Fish” the Green wire from the Output Jack cavity to the pickup
cavity, then to the control compartment. Attach a wire to one end of the Green wire by
wrapping it around the terminal and pull it through to the pickup cavity, then push it
into the control cavity as shown in Diagram #1.
After the Green wire is fished through, push
through the white output cable as shown.
Refer to Diagram #3
Push the terminals onto the jack.
White wire to the TIP Contact
Black wire to the SLEEVE Contact
Green wire to the RING Contact
Install the jack onto the jack plate and screw it into place.

Slip the heat-shrink tubing over the Green wire from the output jack.
Use the Spade connector to join the Green wire from the output jack
to the Black wire of the Battery. Cover the connection with the heat
shrink tubing provided to insulate the connection.
This completes the installation. Be sure to test the pickup and preamp
by tapping on the pickup with a small screwdriver. Also, be sure to insulate
the battery with the foam piece provided.
