Thanks for the help people.
Jazz noise, I think you've got it. I went to the shop a few days ago and the guy told me to raise my action and hence tension of my trebles and it sounds better. I've just realised that the 1st string on my acoustic is 14 or 15 as opposed to a 10 on my electric :D no wonder
decay-o-caster, I do realise that bowing on the harmonic node doesn't bring out the sound and it really sucks because the contour of my guitar forces me to bow before 14th fret if I want a clean single string.
I haven't tested it extensively but that should be it
(somehow I can't get my signature to show although I checked "show your sig" ...)
EDIT: nevermind it's just this thread
