tuning to 432 vs 440
OK folks here's my $0.02
As far as tuning down to 432 is concerned, yes it will make a small difference to your tone, since the harmonic series of the note will all be slightly lower in frequency. As devine sid, there is a complex explanation involving beats et al.....
Also, guitars use equal temperament scales, which is a best case fit, in order to play in every key. If you wanted to play in true perfect pitch you either need....(a) a fretless instrument and a phenominally good ear (like really good concert string players) or (b) a different guitar for every key....and not just tuned differently, the fret spacing would be microscopically different too....
Anyway, that's all physics and I had enough of that while studying (though i can dig it out if people are THAT interested).
If i remember correctly, Van Halen used to tune his guitar by ear, not a tuner, just so that it was in with itself, then Mike Anthony would tune his bass to that, then off you go.....it is roughly a semitone flat, but wanders a little from song to song, album to album. On stuff with Keyboards in (Jump etc) they tuned to concert (440).
Thats why you need two guitar to play along - and even then some of them are a little off.
