At the last part of Metallica - Unforgiven II (5:46-5:49) there is a weird 'bubble-like' sound. it also sounds like some skype notification to me.

does anybody know what makes this sound? as far as I know, none of the rock instruments produces a sound like that.

(I checked many official releases of the song and they all have it)

    Can it be the guitarist's fingers sliding on the strings?

  • I don't think we are talking about the same sound. I have heard sliding many times with both slider on/off but they don't produce a weird sound like that
