Asymmetrical Neck Profile

Electric guitar players tend to hang their thumb around the lower strings when playing bar chords or closer to the root position, and that thumb tends to shift towards the back of the neck when playing on the highest strings farther up the fretboard when soloing.  It may be considered bad form to classical guitarist, but for a number of reasons (nut width, chord types, and musical styles) it is the way many electric guitar players have come to play.  

Our neck shapes all come with a subtle asymmetrical tapered neck that has more meat behind the thicker strings towards the nut and that centerline of mass gradually works its way towards the middle of the neck at the 12th fret.  This is done to provide support, and prevent fatigue for the vast majority of players who have come to utilize their thumb when playing chords. 

If this seems strange to you, believe me we get it.  I personally grew up on modern D, and C shapes, and never would have considered something like this, until I accidentally shaped a neck that was asymmetrical.  It felt far more comfortable after playing a several hour gig, and I understood why those coveted 1959 Les Pauls all tended to have a slight asymmetry to their neck profile.  Our hands aren't symmetrical, so why should our necks be?
