I'd love to hear some playing using an F# string. I can't imagine what on earth it's used for, lower than that horrible sounding bottom A on a piano.
My only delvings into 'sub contra', and only by a smidgeon, is detuning the B string to Bb for some songs. It does throw my fretting out a bit though having to think about Bb E A D G tuning.
What styles of music are using these mentally low notes?[/quote]
Doom
Actually, doom rarely has the sophistication for low F#, don't actually know where that is useful. Can't really generate Doom SPLs with that sort of lows.
