For interested creative people who already have their wastebasket full of body designs, the "crossing" could provide variety.

Take two raster drawings, for example this one with two bestsellers by Leo Fender:

<> The older guitar – TELEcaster


and a guitar AXIS, later born under the company logo MusicMan.



Both contours on top of each other

At first glance, I think they both look quite different.


Middle profile of both contours

But if one determines the mean values (graphically) from their checkpoint coordinates and connects them with a smooth curve,


T e l a x

you get an faultless body shape with the DNA of both templates:



Hybrid from LP und PRS

When comparing two or more contours of guitars in the coordinate system, we place the drawings on top of each other so that the zero points are in the same position. We choose a different contrasting color for each area.



For example LP and PRS contours. Not only comparisons, but also combinations (hybrids) are then easy to create.


A small correction in tile number 17 improves the overall impression.

Parker Fly and PRS

Crossing the contours of electric guitar bodies makes sense mainly for shapes that have the same direction of the corners and the opposite buttocks.That's why I chose Parker Fly and PRS.

Their difference in the length of the scale (648 vs. 635 mm) does not play a role here, because the front edge of the neck (NE) has the same position at both contours. We see a marked difference in the position of the AGP checkpoint (GPW belt pin).

The surprisingly identical ergonomics of the two original guitar models is evidenced by the fact that their most important "support points" WNG-WSG, MNG-MSG, and almost HNG, and the CWO CWU cutouts overlap.

The combination of PRS and Axis shapes

The combination of PRS and Axis shapes also promises an interesting hybrid. Including the 635 mm/25”- scale length, which is basically also a "hybrid" of the classic Gibson and Fender scales. The ergonomics of both guitar starting contours are almost identical, especially at the most important AGP and MSG checkpoints. Also, the middle "hybrid" position of the GPO strap button is close to the positions of both PRS and Axis "parents". Therefore, for both sitting and standing positions, the hybrid guarantees the satisfaction of fans of both models.

    Dear Mr. Jirasko,
    I'm also a retired engineer and amateur guitarist.
    Now I want to spend my time making my own guitar, a hybrid between PRS and MusicMan Axis, with scale 25 inch, and fixed Hannes bridge.
    Where can I get your book?
    If you want translation in Spanish, I offer to help you.

    Dear friend,
    I am very pleased that you are interested in my methods of analyzing known shapes of electric guitars, according to which shapes can be synthesized partially or completely new. In the book "E-Guitar Navigator", Chapter 9.1.3 "Neues durch Kombinieren", the hybrid method is described even from three contours (Tele, SG and Mockingbird). I hastily verified your intention, combining PRS and Axis, and the resulting one will definitely be ergonomically and visually perfect.
    My book can be purchased directly from the publisher https://tredition.de/autoren/jan-jirasko-24234/e-gitarren-navigator-paperback-104920/
    Or in Amazon https://www.amazon.de/Gitarren-Navigator-Gitarre-richtig-ausmessen/dp/374695262X
    So far, the book is only available in German, English will be in the fall of 2021. I do not plan to make the Spanish version until the English version is on the market. But your offer is the first step in this direction.
    :) J.J.
