Fender intonation question!........

This. It should have a longer screw for the G for that year of Fender. I've always thought that was one of the dumbest things Fender ever did. "Oops. We put the bridge on too far back. Instead of moving it forward, let's just put a longer intonation screw on there for the G!"

It works, and it possibly saved a bunch of mis-drilled bodies from the scrap heap. I have no problem with it, it was a simple and perfectly functional solution. And the factory installed bridge cover hid the bridge anyway. Not really an inelegant solution at all.
 
Hmm. Taking a yardstick, the inside edge of the nut to the crown of the 12th fret is, of course, 17 inches, 1/2 of the 34 inch scale, and therefore the 34 inch scale should be from the inside edge of the nut to the middle of the saddle, then compensate from there. Is the adjustment screw long enough to check the scale measurement, before we do anything else?
 
AGAIN

They used steel drilling jigs placed over the cut body and it locks in the pocket. Always have.

Leo perfected assembly line instruments and it just doesn't happen. Unless the workers CAN STRETCH STEEL JIGS

But it did happen. There's plenty of Fender basses from that period out there with the bridges located such that a longer G string intonation was required.

It wasn't a matter of trying to correct for an error in manufacture. From 1969 through part of 1973 the long G intonation screw was a regular production item. I haven't actually measured, but I have heard it was because Fender moved the bridge a bit further back in those years to allow more intonation room for the E string. Consequently they had to lengthen the G string screw in order to intonate it properly.

I didn't mean to imply that it was an error that "did happen", just that the inclusion of the extended screw "did happen".

Sorry for any confusion.

Right - I thought I knew what you meant, but I wanted to be sure that someone didn't misinterpret. That's how myths get started. BTW, does anyone know for FACT that Fender did move the bridge a little further back from 1969 to 1972? Next time I see a bass from that era I will measure.

I wonder if this could be related to the introduction of the fretless P in the late 60s? I have a '71 fretless but I've had different necks and bridges on it since I bought it (in 71) and I'm pretty sure it did not come with the long G screw. I do have an old bridge with a long screw, but I think this may date to when I had a fretted neck on the 71 body. It's a hardware store screw, definitely not factory.

Would be interesting to see if the difference between the two bridge placements is the same as (or proportional to) the difference between the position of the dots on the side of the neck. On the fretless neck, the dots line up with where the fret would be, on fretted necks they are centered between frets.

The position of the fingerboard side dots wouldn't effect the bridge position as long as it's the same scale.

I just did a quick Google search and couldn't find anything about the Pbass bridge being moved. :cautious:

Edit: I guess we are both wrong. http://books.google.com/books?id=rC2X0BiF2ZMC&pg=PA1999-IA17&lpg=PA1999-IA17&dq=p bass bridge moved&source=bl&ots=eafb9dDXf1&sig=sNAo_5K97Rb6byPklE1Ut2r57lE&hl=en&sa=X&ei=j4f_U6GmKcaRNsXQgeAI&ved=0CDQQ6AEwAw#v=onepage&q=p bass bridge moved&f=false
Check years 1970 and 1972/73.

I was really just asking a question, but since you mentioned it, didn't the P-Bass get the long screw, too.


That link doesn't mention anything about bridge relocation at all but I've had 2 P basses from that era, a '72 and a '73 with the long intonation screw and bridge set closer to the end of the body. I've also seen several others.

I don't think the longer intonation screw and the pickup position change were related in any way so it wouldn't matter which came first. I don't know who knows but it'd be interesting to find out.

Well, here's something, although nothing definitive.

They needed it all of a sudden, because a retooling put the bridge mounting screw holes approx .5" further from the neck. All of a sudden, the intonation screws were short. This poor placement continued until at least 1983, as my '57 RI P-bass of that year suffered the same problem. At some point in the 90s, I redrilled the holes a bit north of the originals and its been fine ever since, and looks more like my 50s & 60s Precisions too!
