Henry sent me over an old SM56 for repair.
On arrival it worked, but it didn't sound just right.
Next day it sounded different.
So I took it apart to investigate.
The little black wires that go from the main body to the cartridge assembly were a little worse for wear.
So I replaced those.
Here they are cut to fit.
Now....The reason the mic's sound changed.
The diaphragm glue had dried up and the diaphragm was completely loose.
Anything more than a light tap made the whole diaphragm and coil move slightly.
Unfortunately the coil wires had become weak too, and one of them actually broke at this stage.
You can see them here, disappearing into little holes under the diaphragm.
So, now my mission was to find a cheap replacement cartridge for an sm56.
Is it the same as a 57 or 58? Tune in next week to find out.
