ORIGINAL: Ramón Hola all... I am curios about the thoughts of the other luthiers on neck angle relief. My plans call for 2-3 degrees, but I was looking at a nice 70's Conde last night, and saw it had maybe 1°. Some makers claim 'flat'... The flatter you go keeps the strings off the soundboard low, but HOW do you keep to buzz out!!?? The Conde was like 2.5mm off the 12th on the low E - with NO buzz at all. I understand sanding a 'break' in the fretboard, 19th fret, Low E, being the lowest area, but I'm curious how others look at relief, buzz, sanding the fretboard angle, etc... AND!!!...I was curious about a slightly larger fret; a hair wider and taller, as it barrs nicely, but am afraid of more buzzing due to height (although extremely small increases)... I use the FW72 from LMI... Gracias... I've never thought of neck deflection as an angle (although it is of course) rather as a measurement. It's about 2mm higher at the nut than at the 12th fret, slightly more on a classic. If the deflection is slightly off after you glue on the back then you can taper the fingerboard from end to end to compensate. If you make the neck flat (parallel with the top) you'll have to have a large taper end to end on the fingerboard or the saddle will be too tall. My understanding of "relief" is a very slight warp in the fingerboard. If the neck deflection is perfect I make the fingerboard absolutely uniform from end to end then scrape a taper on the bottom from the 12th fret to the sound hole to allow for the arch in the top and the deflected neck. On flamenco guitars I think the fingerboard should be perfectly straight and flat with the strings off. If the slots are cut the right size the frets should need almost no dressing after they are installed. The string tension pulls a very slight warp into the fingerboard if the neck is sized correctly (relief). Big frets do not cause excessive buzzing.
