K&K Sound ULTRAPURE RETRO Product Manual

U L T R A P U R E " R E T R O " P R E A M P
Thank you for choosing the K&K UltraPure "Retro" Preamp! The following instructions will cover the installation
and use of the preamp. Please install the pickups according to the included Pure Pickup instructions.
INSTALLING THE PREAMP
1. Remove strings for best access.
2. The preamp is mounted using the supplied magnet and
the double-sided adhesive.
3. The magnet is already attached to the preamp. It clings
to the steel casing of the preamp. The magnet comes
with an attached industrial-strength 3M adhesive.
4. Inspect your guitar for a suitable spot on the inside
edge of the sound hole. For most secure results, it must
be a flat surface without obstructions. (In rare cases
where the soundhole bracing is too high to allow the
magnet to sit flat, you may have to add a reinforcement
or try a different location.)
5. Once you've decided on the location, slide the magnet
off the preamp, remove the white protective backing
from the adhesive and stick the magnet to the chosen
spot.
6. The magnet is brittle, so VERY carefully "snap" the
preamp to the magnet.
7. The battery holder can be attached with the self-adhesive Velcro. It should be located on an accessible spot
like the neck block or another safe location of your choice.
8. When changing the 9-volt battery, we recommend you pull the entire holder off the Velcro and replace the
battery outside the sound hole. Make sure the battery snaps all the way into place. Then stick the holder back
on its Velcro pad. If the Velcro starts wearing out, you should replace it. It usually holds up for several years.
