Floyd Rose Oddball Intomation Problm on High 'e' Only:

I'm putting EB Paradigm's on it - a hybrid set :

.009"
,011"
.016"
.026"
.036"
.046"



It had 3 springs on it with the claws bottomed out. I installed 4 springs in a straight line and the claw was backed out about 1/8" at pitch and parallel to the body...

Yeah. I'd switch to 9's and try again. That hybrid set may set up okay.
 
BIG PROBLEMS - Bridge stud inserts fell out in the floor. The insert is .400" OD and the holes in the body is around .410" ID. I think this has something to do with the intonation problem...Anybody make them oversize OD????

Put new strings on it and try it again.Put the strings on then tune it to pitch,make sure the Floyd sits level,if not adjust the springs till it does after tuning to pitch,once this is done then check intonation again
That's what you expect. It needs moving back.


So, it appears there are no oversize bushings available. So, I am considering this:

Carbon Steel Spanner Bushing Spacer Reducer 12mm OD 10mm ID x 1-5/8" Long

The hole in the body is about .410" ID. There is enough room to drill out to 12mm (.472") and the average replacement Floyd Rose Bushing is 10mm (.393") so the threaded bushing could be Loctitied into the reducer bushing....

Found this little jewel on E-Bay:

At least this is a solid method of repair I think...but I have one question:

The bridge was tilted towards the nut. The high 'e' saddle was all the way towards the nut and the fretted note at the 12th ret was still FLAT.

Would the effect of moving the bridge rearward, by eliminating the tilt of the loose bushing, cause me to need more saddle movement towards the nut that I am already at the llmit of????

Most likely, yes. But, make the repair and try the '9s.

Ok, I may have solved the mystery of why all the saddles were moved all the way forward on this guitar. All were intonated except the high 'e,' but the guitar never sound right. My first thought was a mathematical problem.

Measuring the distance from the nut shelf to the posts on the Floyd rose, I came up with 25.625"

So, I did some more investigation. Turns out the guitar has a fender Cyclone neck, which is 24.75" scale, verified by measuring from the fretboard edge of the nut shelf to the center of the 12th fret, which came out as 12.625" - which still isn't correct for a short scale - the correct distance should be 12.375" on a 24.75" scale.

This means the bridge is 1/4" (.250) too far rearward, which causes you to have to move the saddles all the way forward.

There's more...even though intonated at the 12th fret, it sounded off in the lower register, so I started measuring the fret centerlines from the fretboard edge of the nut shelf:

1st fret: 1.380"

2nd fret: 2.682"

3rd fret: 3.915"

12th fret: 12.625"

According to the Stewi-Mac calculator, the above measurements should be:

1st fret: 1.389"

2nd fret: 2.700"

3rd fret: 3.938"

12th fret: 12.375"

This was definitely not right, so what I came up with was, this must be a mix matched pile of parts that cannot be "fixed" in the traditional sense.

Got some history on this guitar. Its a partscaster with a Jackson neck...most likely built from scraps.

Now it makes sense.

BTW, does the owner think the neck is from a Jackson Pro Soloist? The Pro Soloists are made with neck-through construction. There are other Jacksons that do use bolt-on necks, but not the Pro Soloists.

I think he was sold a bill of goods....I've shown him all the Jackson models. This one is nothing like any of them, but he's not out very much....
