And one urgent addon:

the subtractive synthesis expects most time a continous input signal.
E.g. an synth VCO produces continuous sound all the time. The guitar
string cannot provide that, so you definitily always should have two
versions of your guitar signal:
1.) the original which you use for envelope shaping, which should be as
dynamic as possible
2.) a clean, but highly compressed audio signal which should be used as
audio for postprocessing filtering, ring modulation and similar. You may
use the envelope follower, a inverter and a VCA the of the A-100 for
this task, but an external compressor will do it most times much easier
and much better and last ut not least for less bucks.
Only for distortion based processing the dynamic signal is better as audio.
