Physical modeling seems to work really well for guitar/bass amplifiers. The Fractal Audio products are all based around simulating the various components of an amp and the ways they interact with each other, often with very unexpected results. They've been pushing in this direction for quite awhile, but I think it is more promising than capture-based tech ultimately.

The modeling is so accurate that it ends up replicating even the unintended side effects of amps, such as ghost notes (false notes being produced due to the power supply). The tech note explains it better than I can: https://forum.fractalaudio.com/threads/ghost-notes.126903/
