*I was wondering if you can produce realistic sounds by literally solving
the **string equation for an electric guitar...*
Perhaps, but you would probably have issues with performance -- you may be
able to get a good sound, but it would be difficult to generate it in real-
or near-real time.
For strings (and some kinds of percussion) physical modeling is often used,
but not taken in the direction of modeling the string or membrane. The most
common form of modeling is digital waveguide synthesis
<https://en.wikipedia.org/wiki/Digital_waveguide_synthesis>. One of the
earliest "good sounding" approaches was probably the Karplus-Strong
<https://en.wikipedia.org/wiki/Karplus%E2%80%93Strong_string_synthesis>
algorithm, which is usually considered a physical model (albeit a pretty
abstract/conceptual one).
You may want to look at cSound's repluck (which is based on Karplus-Strong).
