A microphone is
never dead
Repair and rewinding
I am no longer taking on repair work at the moment, please forgive me.
A guitar microphone that no longer shows any sign of life does not mean that it is good to throw away. A false contact or worn solder can be the cause of a lack of sound.
By exposing the microphone and accessing the coil(s), we can determine the origin of the fault quite simply.
If the short is inside the winding, rewinding is necessary.
Did you say “almost”? Some microphones are cast in epoxy. Unless there is a very superficial breakdown, they are very difficult, if not impossible, to repair.
Vintage Pickup Repair
Some microphones are impossible to find, especially on vintage instruments from the 50s, 60s and 70s . The pickup models are no longer manufactured, so it is necessary to repair the pickup if you want to use the guitar while retaining its original appearance. I repair all types of microphones , whether for bass or electric guitar , whatever the era and configuration, single or double coil, with or without support coil.
Magnets and Magnetization
Some microphones, particularly single coils, are incorrectly magnetized, resulting in volume problems on certain strings. Remagnetization is therefore necessary in this case. For microphones with a magnet external to the winding, it is possible to replace it in the event of breakage or to modify the sound of the microphone.
The gallery below shows some examples of repairs carried out in recent weeks. I often have to repair/rewind Fender type pickups (Telecaster, Stratocaster, Jazz bass) due to their construction. The winding in the open air, the connection of the winding wire directly to small eyelets, makes the microphones fragile.
