magliari scale flat fretboard

[Phil Goodson]

The classified section has a Duff F-5 that the seller says has a new "magliari scale flat fretboard". Anybody have any experience with this? Apparently involves an intonation correction technique by Magliari & MacRostie?
Is this something similar to Buzz Feiten or Earvana modifications???

A couple of quick Google searches show Gary Magliari involved in studies concerning nut & bridge compensation. I'd never heard of him or his work, but that's probably just showing my ignorance.
I'd ask if the nut is compensated. If so, then it may be similar to the Buzz Feiten and Earvana solutions, which involve both nut and bridge compensation, but an otherwise standard fretboard. Some makers have compensated (or rather tempered) the frets themselves, which, as you can imagine, is pretty drastic.

Marty, I really don't want to level and recrown those frets.

The curved fretboard is easier to play... Just kidding I really have no idea. I have looked at this kind of fretboard and decided that in the heat of battle if I was 2-5c out somewhere I wouldn't notice. Seriously be aware any string gauge change or bridge adjustments will negate all the hard work.

You wouldn't want to refret one, or is that the built in money maker ? always having to send it back for fretwork ?

Timely thread.
Gary Magliari and Don MacRostie's presentation at the 2011 GAL Convention is in the next issue of American Lutherie #116.
As I remember the idea involves not only compensation of the nut and bridge but modification of the fret spacing up and down the fretboard from a set point (fret). The result is not a true tempered scale but a compromise that gets you much closer than the traditional "Rule of 18".
All the more reason to join the GAL.

I will look forward to reading that. Thanks for the tip, Eric.

I'm with you Bryce.

All you expert builders: how do the Feiten and Magliari (!) systems relate to our mandolin. How many folks compensate both the bridge and the nut on mandolins?
