In those diagrams you moved the neck pickup. In reality, the neck pickups on PRS gtrs dont move, the bridge and the bridge pickups do. Compare a Custom 22 to a 24, and measure the distance between the pickups. Its SHORTER on the 24.
O.M.G.
Please just look at the diagram without the body outlines... You can see from the drawings (even in the drawing with guitar bodies) that the space between the pups is smaller and that the neck pup is closer to the bridge on the 24! Not in dispute!
What IS in dispute is WHY.
The illustration without the bodies clearly shows the body has NOTHING to do with it.
Neck pups are positioned at the end of the fretboard. A longer fretboard (by 2 frets) means less space available.
Put the body anywhere under the bridge and the neck pup on a 24 fretter and it will not change the space available for the neck pup.
Disprove any of the following statements.
A 22 fret and a 24 fret guitar of the same scale have the same distance from the nut to the bridge.
A 22 fret and a 24 fret guitar of the same scale have the same distance from the nut to the 12th fret.
A 22 fret and a 24 fret guitar of the same scale have the same distance from the nut 22nd fret.
A 22 fret and a 24 fret guitar of the same scale have the same distance from the bridge to the 12th fret.
A 22 fret and a 24 fret guitar of the same scale have the same distance from the bridge to the 22nd fret.
The placement of the bridge on the body and the attachment of the neck to the body alter none of the above measurements.
The length of the fretboards for guitars of the same scale is different for a 22 fret guitar vs a 24 fret guitar with the 24 fretter being physically longer.
Since all other dimensions are the same
except the physical length of the fretboards, THAT must be what limits how far a pup can be placed from the bridge without putting it
under the fretboard.
I refer you back to the illustration without the guitar bodies....
