That particular algorithm doesn't care whether the instruments are guitar or otherwise. There are other algorithms in vamp that would deal with individual notes. But in terms of separating tracks, vamp doesn't do that. There are some new ML-based solutions for this though. So you could separate them and run vamp on those outputs.

But to get the chords I don't think you need to worry about that.

To add to this, it’s vanishingly seldom that you would have a finished track where multiple parts of the ensemble are playing different chords, rather than each part making up the same overall chord structure.
