Citaat:
Microphonics is that squealing or knocking sound you hear when you tap on a pickup. A good example of microphonics at its worst would be the Fender Telecaster bridge pickup—not only do you have a coil of wire and magnets, but you have a steel plate under it and a steel bridge around it. Fender used to mount the steel plate after the pickup had been potted, and that's why the Tele is so notoriously microphonic—the steel plate vibrates. For that reason, I pot my Tele bridge pickups after the plate is mounted.
Dat verklaart een heleboel, budgetmerken als RW zullen niet te veel moeite doen om dit te voorkomen. Ik zal es ff googelen of ik nog een waxpot minicursus ergens kan vinden.
