Hi Guys...
I got my old Fender out of the closet today, and plugged it in.....there is a small problem that I am hoping someone can help me with.
The trapezoid pickup on the outside neck is noisy (microphonic?)....there is distortion coming out of the amp when you hit more than 1 string...if I hold my hand down with a bit of pressure on top of the pickup, the distortion is less.. the other two necks have very little distortion.
Anyone have a quick fix for this? I appreciate all your replies.

| Billy, this sounds like the problem Rick Aiello describes. There is a fix for it on Rick's site. |

Take a flashlight and look into the orifice.
The bobbin often sags down from the top ... and/or ... rises up from the bottom.
It should be plainly visible if this is the issue ... and since you said it lessens when you press down ... sounds like the bobbin's pokin' up.
If that is whats going on ... build little 3/16" tall shims made out of wood or plastic ... round the tips like a suppository ...  ...
And gently insert them between the strings of the offending hump ...
If that's not the issue ... you may want to try tightening down the whole unit ...
There are instructions on my site for removing the magnets ... that will get you thru the process of lifting the unit ...

If those two things don't work ... sounds like it's time to send the unit to Jason Lollar ... give him a holler at info@lollarguitars.com |

Don't feel too bad about using Rick's shim repair, Leo used that design on the later traps to keep them from drooping.

They're not rusty, they are "battle hardened."

Mike, It was some sort of plastic that shrinks and distorts with age. I made one out of "fish paper" (high dilectric cardboard) once and that worked. There are probably several good choices for bobbin material out there. If it is just drooping and has not affected the windings yet, just prop it up and leave it.

Mine appears to be a card stock thickness paper product that was shellacked / varnished/ lacquered ??? ...
I imagine those that were well cared for and kept in their case ... are the ones that still are true.
Humidity probably is to blame for the warping.
My Boxcar has one "post" ...
I've seen some Boxcars with two "posts" ... even saw one with a post between every string.
Some traps had a post also ... like the second photo that John posted
Mine doesn't ... well, now it does ... two pediatric Ear Curettes ...  
Taking a "que" from Danny James ... when I started winding my own MRIs (same "air coil" design) ... I use polycarbonate (Lexan).
I'm not sure exactly what Jason Lollar uses to rebuild them ...
The "Original" MRI bobbins he built... seemed to be a paper-like product ... seemed a tad different than forbon though ... it was white. |

IT WORKED!! I used a 3/16" wooden dowel about 1" long; 3/16" was just a little too big around, so I sanded it down and put it in there...and it worked! Thanks, guys...don't know what I would do without my forum friends.
