Would someone know what the scale length is on the fiberglass body National 35? I have one that has had the zero fret removed & the nut moved up into that position (butting up to the fret board end). On an original Model 35, would the scale length be measured from the zero fret to the bridge saddle, or from the nut to the saddle?
I am having difficulty with intonation of the 'B' string; the guitar is tuned to open 'G'.
I have ordered a compensated bridge/biscuit from NRP in the hopes that it will get intonation better!
Any advice would be most appreciated!

Any advice would be most appreciated! The scale length is twice the length from the nut to the 12th fret . Usually the bridge has some compensation, so the distance from the nut or the zero fret to the bridge on a 25” scale will be 25 1/8 or longer on the treble side and 25 1/4 or more on the bass side. If I were converting a zero fret to a normal nut I would cut on my he zero fret slot to give the correct place fo the nut. Hopefully this is what happened to your guitar Try using a capo on the 1st fret, if the intonation is still out ( at the 13th fret) then the bridge, action or strings are to blame Pete |

If the guitar is ok with a capo, the nut is probably too high. The thickest plain string will sharpen most , so that is usually the B on acoustic guitars. This string also needs more ‘compensation ‘ than others at the bridge to get intonation perfect.
Pete
I used to worry about these things but most classic tracks were recorded with guitars with straight saddles that would never pass an intonation test with a modern tuner, I am happy with good intonation rather than ‘perfect’.

Yes, I believe the nut height does need to be lowered. The compensated bridge & the lower nut will (hopefully) get intonation better. As soon as the Mail gets thru...

You say you are in open G. It's always necessary to flatten the B string a little in this tuning to get it to sound right.

You say you are in open G. It's always necessary to flatten the B string a little in this tuning to goet it to sound right. I do flatten the 'B', but it is just more out of tune than usual. The replacement nut was way too high. A combination of things - always! |

The compensated National saddle/biscuit turned out to be a huge intonation corrector on the guitar. String spacing is 60mm; top quality product with excellent photo instruction sheets for proper installation. The guitar has become a more versatile instrument as a result of the mod, tunes up well in various tunings.
