ADJUSTING THE PREAMP
The PowerMix System comes with a long blade
precision screwdriver to adjust the trim pots on the
preamp board. It also includes a sticker that
describes the thumbwheels and the trim-pots
function which you should attach somewhere inside
your guitar case.
The photo below shows EQ settings on the preamp
board that we recommend as a starting point.
Please look closely at the white indicator arrows in
the center of the trim pots.
Undersaddle channel:
•
boost bass (ca 2.30 o'clock on the little white
arrow indicator)
•
cut mids all the way left
•
cut treble (arrow indicator ca 9 o'clock)
•
gain ca 11 o'clock
Pure Pickup channel:
•
bass and treble almost flat (arrow indicator 12
o'clock)
•
cut mids all the way left
•
gain ca 3 o'clock
This is only a starting point. We try to set the gain
trimmers so both pickups are about equally loud
when the according thumb-wheel is full up.
At a performance we generally recommend to use
as much Pure Pickup as possible and then add
undersaddle sound as desired.
INTERNAL PREAMP INSTALLATION
The preamp is attached with a self-adhesive Velcro
fastener. For convenient access, it is best to mount
the preamp directly under the sound hole. This
allows for quick access to the EQ trimmers with a
long, small blade screwdriver.
If you do not want to stick Velcro directly to the label
of the guitar, we recommend this temporary
mounting technique: Use the supplied 6” strip of
Velcro and trim the length and the protection paper
as shown in the photo. Usually there is about 3
¼
”
(85mm) distance between the 2 braces. Please
measure your guitar and trim accordingly. Stick one
Velcro-end to one brace, pull the strip tight and stick
the other end to the next brace. Now you can
temporarily attach the preamp to this strip.
If you prefer, you can keep the preamp attached in
this way. It is actually quite sturdy. However, once
you are done with your sound adjustments you can
move the preamp to another location, deeper inside
the guitar.
INSTALLING THE BATTERY HOLDER
Please install the battery holder to the neck-block
with its self-adhesive Velcro fastener. To change
batteries we recommend you remove the entire
holder, change the battery comfortably under the
sound hole, and re-attach it to the neck-block.
