Vibrato Scanner
 
I have been having a problem with the vibrato (the part that raises and lowers the pitch very quickly).  Whenever I have it on the sound gets very distorted and quiet.

I took apart the whole vibrato scanner (there are about 5 other pieces on each brass bolt, and them some more on the back) and soaked the components overnight to clean them.  I reassembled it, but the problem wasn’t fixed.  I even have the problem when the scanner is not connected to the motor, so I’m not sure what it could be.
