Introduction
Thank you and congratulations for choosing a Shadow pickup system. Shadow preamps are known for the most reliable, user-friendly and best
sounding products on the market. As a result of an enormous research and development effort over many years, Shadow releases a revolutionary
new stereo pickup system. The NanoFlex-6 pickup combines six small Nanoflex pickups with individual gain control.
Onboard Preamp Installation
Slide the preamp along the guitar side to find the point where the curve of the preamp matches the curve of the guitar. Mark the positions of the
ends of the preamp and place masking tape across the side of the guitar. Measure the total width of the guitar side and mark the center point. Place
the template sticker between the stripes of tape with the center marks lined up. Cut out hole in guitar body following the inside edge of the black line
of the template. Place the preamp so that it fits precisely and drill with 1mm drill diameter four outside holes to fix the preamp. Connect pickup cable
and endpin output cable to the preamp and mount the preamp into the guitar’s side. Use included cable holders to fix the cables inside the guitar.

(1) Exchange Batteries*
Push the battery compartment
(1)
cover to the right and cover will pop up. Insert two batteries. The positive pole of the battery near to the hinge is
up and the next battery show negative pole up. See Fig.1 for details. The battery turns on automatically, as soon as you plug the instrument cable into
the endpin. To spare the battery life, take the cable out, when not used. If you don’t want to use the unit for a longer period remove the batteries to
prevent leakage. Fresh batteries may last up to ~180 hours when it is used under normal conditions. (Tuner = Off).
*Notes of battery disposal:
For EU:
The crossed-out wheeled bin implies that used batteries should not be put to the general household waste!
There is a separate collection system for used batteries, to allow recycling and proper treatment in accordance with legislation.
For other countries:
The used battery is to be returned to the selling point. Or contact your local authority for correct method of disposal of used batteries.
(2) GAIN Controls
To adjust the single string gain (+/- 3 db) turn the small trim pot knob with the pick or finger nail. To increase the volume turn to the left from the
middle; to decrease the volume turn to the right from the middle. ATTENTION: Do not overturn the gain pots – this may damage it!
(3) PAN Control
For this unique sound, simply connect your guitar by way of a standard stereo
Y-cable to the mixing board.
Adjust the panorama of your mixer to the left and right.
Turning the PAN control clockwise separates the strings of your instrument
step more. This brings about a tonal depth that up until now did not exist.
Fig. 2 shows the amount of the left and right signal controlled by the PAN control
0%
(Mono)
50%
100% (Stereo)
(4) VOLUME Control
This control adjusts the overall volume. Normal operation should be between position 6 and 8.
(5) (6) (7) TREBLE, MID, BASS Control
Bass, Mid and Treble will change the EQ to desired sound. For a good weighted sound you can set all 3 EQ controls to the mid!
(8) PHASE Switch
Depending on the environment some feedback - which means awkward sound on one frequency - may occur. This has a physical background and
depends on the position between your instrument and speaker. A good method to lower the risk of feedback is to turn the phase by 180° to change
the physical conditions. Very often it helps, but sometimes it will support the feedback or just change the frequency of the feedback. In this case
switch the phase back and try to change your position.
(9) (10) TUNER Switch and Display
Press the switch, to start the tuner operation. This mutes the analog output. The display
(10)
shows the note played and both LEDs HI or LO showing
how close it is to the correct pitch. If you reached the final pitch the LED OK lights up. Press the switch again, to end the tuner operation. If the tuner is
not in use
(no input signal)
for ~90 sec. the display will be switched off to save battery energy. This is shown by a flashing dot of the display.
(11) BATT.LOW LED
The voltage of the battery is always measured. Below a certain level – which means the battery capacity is diminished – the LED (11) starts to light.
Then you should exchange the batteries soon.
