Resonator Cone Care
Over time, aluminum resonator cones begin to lose volume and tone.
This is due primarily to metal fatigue (caused by consistent string
tension and vibration) and surface oxidation (think rust on steel).
We recommend cone replacement after 2 years of regular playing.
One sure way to get the best out of your
Acoustic Resonator Guitar
is to keep it clean. Not only will dust and lint build up kill the tone of
your resonator, it also speeds up the oxidation process.
A Note on tension screws
An improperly adjusted tension screw will not only kill the tone of your resonator but in the worse case, damage your
cone! The cone should only have 1/4 to 1/2 of a turn of tension on it total, with the strings tuned to pitch.
Install the cone with the screw through the spider and tighten just until the head of the screw touches the top of the
spider with NO tension on the screw. This is the starting point for the tension adjustment. The spider sits on the cone
and the screw is just there to add a little tension.
It is not there to hold the spider on the cone, (the string pressure does this). After stringing the guitar and tuning it to
pitch, you can adjust the screw.
You may have to tighten the screw down until the head of the screw touches the spider again as the cone sinks with
string pressure. From this point, tighten the screw 1/4 to 1/2 of a turn.
