Ever had a guitar that is just wonderful apart from when you turn
the gain or volume up loud and suddenly it emits a high pitch
squeal that even has the neighbour's pet dog running for cover??
This is what is known as microphonic feedback - and the most likely
culprit is the pickups' coil windings being microphonic (in some
cases you can talk into the pickup and hear it through the amplifier -
just like a mike).
Expensive pickups are usually well and truly wax dipped (potted)
and as such are not so prone to this problem, but many pickups
are not and the resultant feedback is just horrible. Some older
pickups that may have been wax dipped may exhibit feedback as
the wax has dried out and no longer holds the coil windings firmly
But help is at hand!!
We have a wax dipping facility here that can eliminate most cases
of micro phonics in a pickup.
So whilst we are more than happy to offer one of the fine replacement
pickups that we stock (Remember that we keep Bare Knuckle pickups,
Seymour Duncan, EMG, Dimarzio and Kinman), we are now happy to
offer wax dipping to rectify the problem that may be spoiling
an otherwise fine sounding pick-up.
Charges start at £15- excluding removal
