The “Radius” is a revolutionary new soundboard
transducer, capable of reproducing the true acoustic
tone and characteristics of your instrument. It has
been designed/tuned for use on mandolins but
can also be utilized on violins or other small framed
instruments within the same frequency range. It
installs simply and non-destructively to the top of
your mandolin with putty or a peel and stick adhesive.
This adhesive will hold rmly to the instrument while
remaining pliable and easily removable.
Caution: For more delicate nishes like violin or
if you are at all concerned about nish safety we
have provided a special putty to use in place of the
adhesive pad.

• Attach removable jack/clamp to the side of the
instrument following the instructions in 4.1.
• Put a dab of putty on the underside of the Radius
and smoosh the pickup onto the instrument top
behind the treble side of the bridge; (see g. 1 for
recommend placement).
• Plug in and go.
• Reposition the Radius around on the top until
you’ve found the sweet spot.
• If you wish to make the installation permanent
follow the instructions below.

First choose where you will install the jack. We oer
two options: 1) Non-permanently mounted on
the side of the instrument using the pre-soldered
clamp/jack or, 2) Permanent tailpiece installation.
The pickup comes pre-soldered to the clamp/jack so
that you may quickly and easily install the pickup for
immediate results. The wire is longer than necessary
to allow for alternate installations. You can choose to
either tuck the excess wire under the tailpiece or cut
it to the preferred length and re-solder it.
4.1 Non-permanent external clamp/jack
installation: Open the jaws of the clamp until it
ts comfortably over the side of the instrument by
turning the threaded adjusters counter clockwise
(See g. 2). Set the jack/clamp in place with the
protective cork pads completely covering the
upper and lower edges of the instrument. Using
the enclosed key gradually tighten the adjusters,
alternating between the left and right side until the
clamp is securely fastened (See g. 1 for recommend
jack placement). Be careful not to scratch the
instruments nish with the key.
4.2 Pickup Placement: The pickup may be installed
one of three ways: On the top with mounting putty,
on the top with non-destructive double stick
adhesive, or internally with semi-permanent VHB
adhesive.
• First, nd the sweet spot. With freshly cleaned
ngers, tear o a dab of the putty (included), and
spread it on the entire bottom surface of the pickup.
The Radius is rather lenient for placement, but
we recommend you begin behind the bridge on
the treble side of the top (See g. 1). Make sure to
thoroughly clean all dust, oil, and ngerprints o of
the top of the instrument prior to installing the pickup.
Set the pickup onto the top of the instrument in the
recommended area and apply moderate pressure
twisting it back and fourth until it feels secure. Now
plug the pickup in to a high quality acoustic amplier
or PA and listen. Experiment with placement until
you nd the best location/sweet spot. Once you
have chosen a location you may replace the putty
with the clear double stick adhesive (included) for a
more secure installation, or if you like you can keep
the putty as the nal install. Note: The longevity of the
