Emulating guitar pickup position with delays
i won't divulge some proprietary information i have about how to do this, but i'll tell you this hint:  


the vibrations on the guitar strings are standing waves.
standing waves as well as any waves on a string are made of of sinusoidal components with frequencies at harmonic intervals, that is each harmonic sinusoid has a frequency that is an integer multiple of the fundamental which is the frequency we will normally associate with the pitch of the note.
with standing waves, there are nodal points for each harmonic at distance that is a submultiple of the length of the string between the bridge on the right and the fret that is terminating the string on the left.
even-numbered harmonics will have a nodal point at the middle of the string and odd-numbered harmonics will not have a nodal point there.
there is a relationship between ration of the even-harmonic energy to the odd-harmonic energy and the position of the pickup and with the position of the pick.


have phun figgering it out.
