PATTERN NECK SHAPES - CURRENT
Neck shapes have always been a high priority for PRS and a hallmark of our quality. A guitar should feel comfortable, like "home," as soon as you pick it up, and the neck is paramount to that connection. These new neck shapes reflect modern tooling and programming that allows us to even more preciously shape and consistently reproduce our necks.
Perfected after years of prototyping, the new "Pattern" neck is an updated Wide Fat PRS neck style based on Paul’s pre-factory design. These necks were found on the instruments built for Carlos Santana, Peter Frampton and Howard Leese from the late 70’s to the mid 80’s.
The new "Pattern Regular" neck shape is similar to the traditional PRS regular neck found on guitars made in the late 80’s at PRS’s former Virginia Avenue location.
The "Pattern Thin" neck is an updated version of PRS’s traditional Wide Thin neck.
FORMER NECK SHAPES
The Regular (sometimes called Standard) neck is a round neck shape that is 1/32 narrower and not quite as thick front to back as our Wide Fat neck.
The Wide Fat neck has the same nut width as the Wide Thin neck, but it has a deeper profile. Because of its strength and longer "heel", the Wide Fat neck produces warm tones with lots of sustain.
The Wide Thin neck has a thinner profile front to back than the Wide Fat. It is a favorite of fast players and lead guitar players.
WIDTH OF THE FRETBOARD AT THE NUT:
* Pattern, Wide Fat - 1 11/16"
* Pattern Thin, Wide Thin - 1 11/16"
* Pattern Regular, Regular - 1 21/32"
WIDTH AT THE BODY
* Pattern, Wide Fat - 2 1/4"
* Pattern Thin, Wide Thin - 2 1/4"
* Pattern Regular, Regular - 2 1/4"
NECK DEPTH AT THE NUT
* Pattern, Wide Fat - 27/32"
* Pattern Thin, Wide Thin - 25/32"
* Pattern Regular, Regular - 27/32"
Essentially there appears to be only 3 choices for neck carve.
1. Pattern (Wide Fat)
2. Pattern Thin (Wide Thin)
3. Pattern Regular (Regular)
I can find no unique dimensions for "Santana" or "DGT" on "513" other than the Santana is 11 1/2" radius instead of 10" and has a scale length of 24 1/2 " instead of 25". Scale length of the 513 is 24 1/4 ". Does anyone have hard data on the other specs for the Santana or 513 neck carve?
Does anyone know the specs on the DGT neck carve? Or are they just one of the standard three (non 12 string) choices?
Whatever the unique dimensions of the Santana, DGT and 513, and lacking any other data, it would seem that:
A vote for Pattern is also a vote for Wide Fat and vice versa. (28 as of this post)
A vote for Pattern Thin is also a vote for Wide Thin and vice versa. (16 as of this post)
A vote for Pattern Regular is also a vote for Regular and vice versa. (10 as of this post)
