What neck profile does your guitar have?
Having a comfortable neck is one factor that I think is often overlooked when choosing a guitar. Sometimes we might be looking for a guitar without having the ability to physically test it out before buying. It might help to know what a guitar’s neck profile is before taking that blind plunge. So I’m asking you, for those of you who don’t mind doing this sort of thing, to submit your guitar’s neck profile.
To do this, I suggest following these directions:
1. For a baseline, measure your guitar’s neck in millimeters at the 5th fret: its width from edge to edge.
2. Measure its depth from the very top of the fretboard to the deepest point in millimeters at the 5th fret.
3. Using standard printer paper, draw those points and connect the width points by drawing a horizontal line on the paper. This is your exact fretboard width.
4. Using a compass (or freehand) connect the ends of the horizontal line (fretboard width) to its depth point.
5. You should now have your guitar’s neck profile drawn exactly as it is at its 5th fret.
6. Open the attachment showing diagrams of different neck profiles and place it on your computer screen.
7. Place your paper on top of the computer screen and superimposed your drawing of your guitar’s neck shape on top of the different illustrations. Adjust the zoom size until you can get a traced-like image of the profile.
8. Determine which profile fits your guitar's profile.
Note: Depending on your computer's platform, you might have to drag the attached jpg file to your computer's desktop in order to get the illustrations to zoom large enough so that you can match your illustration you made of your guitar's neck to the illustrations in the profiles chart in jpg format shown below.
My Altamira M01 measures 50 mm. across (width) and 23 mm. deep at the 5th fret. It fit the “Big C” profile perfectly. I like this profile because it’s comfortable for me. Neither the palm of my hand nor my thumb is aching after playing long periods or playing day-after-day. According to Michael’s description of the Altamiras, he considers this neck profile to be a “more ergonomic” shape (C shape). The chart illustrates seven different profiles (ignore the specs).
