Good one, Mr.
Pin Head
(...been dyin' to say
that!)
I say it depends what the note is just prior to the "G"...if it's just a 1-bar figure repeated ad nauseum, I'd probably use this LH fingering: 2-3-4-4
(with the index finger stationary/fixed on the 4th fret..."F#").
Using TWO fingers to sound those two notes...IMO, that's "OK" IF...IF you desire a quasi-
smooth transitional sound. Sonically, there is a difference; try both(IMO).
