[LAD] [IDEA] Amp and effects modeling software for guitar

Hello, Few days ago I came up with an idea about an open source guitar modeling software. But because of my lack of knowledge on both electronics and audio engineering I couldn't decide if it worths something. Here it is directly quoted from linuxmusicians.com **QUOTE** Okay! My idea is to use GNUCAP or SPICE to process the guitar signal. These are the top open source analog circuit simulators that are also widely used in the industry for general purpose circuit simulation (not audio specific). You basically feed them the schematics of a circuit and wait for magic to happen. I believe they may be hacked to accept a guitar signal as a varying voltage source. Now there are 3 questions: Is that even possible? If yes, is it possible in real-time? If yes, would results be satisfying (quality and accuracy wise) **END_QUOTE** thanks very much, and sorry in advance if I missed something obvious and this is a completely useless idea
