I was wondering, since we can tune our guitars by cents we can make them sound anywhere close to the note we need. So we can have open A be not 440 but 448 for instance. What restrictions are there not to make it sound bad with other guitars which have A ~440. I assume you can have max 100 cent per note not to go close to a semi-tone?
So for instance if we have A 440 the what is A# Hertz? If we do -50 to +50 around that open A, will it still sound okay with other guitars which are almost 440?
For instance on one guitar A = 442 and on the other A = 467, will they sound okay together? None of my guitar players ever get to exactly 440 on open A.
The idea of this question may be slightly hard to grasp, but basically do the cents matter much? For instance I play on Detuned organ with all notes set to -20 cents and it seems to sound okay with guitar, while we checked that the guitar notes are ~ near the center on the digital tuner.
