Congratulations on purchasing the SCHERTLER® RESOCOIL. It is our pleasure to welcome you to
a growing family of musicians and technicians, including many of the world’s leading soloists and
sound engineers, who have chosen to work with SCHERTLER® products.
RESOCOIL has been specially designed for classical guitar, mandolin, ukulele and banjo players
who want a more permanent microphone solution for their instrument, while benetting from the
same outstanding sound quality offered by our external transducers. During installation, RESOCOIL
can be precisely positioned in order to bring out the best characteristics of your instrument sound, or
to suit your personal taste and playing style. This not only ensures consistency, but also offers added
convenience when quickly switching between instruments during a performance.
All SCHERTLER contact microphones are developed and manufactured according to the highest
standards of design, material quality and workmanship in order to ensure longevity. However, it is
important to always handle your microphone with care so that it will provide reliable service.
In our continuing quest to improve the transmission and reproduction of acoustic instrument sound,
we hope that RESOCOIL will also enhance your personal performing or recording experience.
Stephan Schertler
and the SCHERTLER Team

INTRODUCTION
3
RESOCOIL is a high-quality, passive, electrodynamic contact microphone designed for xed
installation in classical guitars, mandolin family instruments, ukulele and resonator guitars.
Fixed inside the instrument’s sound box, RESOCOIL delivers the warm, natural sound typically
associated with SCHERTLER DYN Series contact microphones, while offering the added convenience
of a permanent installation that leaves no visible holes on the instrument.
To make the most of your RESOCOIL’s capability and to ensure trouble-free operation, please
read this manual carefully before installation. We also advise keeping the manual for future
reference.

You can follow the “Fitting the Microphone”
instructions in this manual. There are also some
tutorial videos on the SCHERTLER YouTube
channel (please subscribe if you like).
However, please bear in mind that the positioning
might affect the overall sound, depending on
your personal taste or the characteristics of
your instrument.
Yes, being a passive transducer RESOCOIL can
simply be connected to the input on the wireless
transmitter, no phantom power is required.
No, superglue creates a hard layer when it dries.
We suggest using contact glue (like the one used
for shoe repair). It becomes elastic enough to
propagate the vibrations to the transducer in a
more natural way, resulting in a natural acoustic
sound. Follow the manufacturer’s instructions to
correctly apply the glue.
