In the Rolling Stones’ “Paint It Black,” there is an odd bit near the end with a “bwoop” sound that is repeated four times in alternate bars. Is this a riff played by the bass guitarist (Keith Richard?) or did Charlie Watts (who had enough to do in this song, goodness knows!) make it with some exotic instrument?
Bill Wyman was the Stones’ bassist back then - Keef is the rhytym guitarist. I can’t listen now - I just boarded a plane - but I think it may be Wyman hitting a chord on bass up the neck…
It’s Wyman sliding a note up the neck of a bass.
Thanks. One of the guitars in that song sounds like a sitar.
It is a sitar, played by Brian Jones.
Yes, before he was murdered. 
How did the Beatles do the sound in the opening of Come Together? You know the one I mean, it sounds like “shhhhhhht-kuh”
It was John Lennon making the shhhhhhhh sound and then clapping into the mic and over-saturating it, or whatever the technical term is.
Lennon is saying “Shoot me”.
Thanks, I never would have guessed it was actually a vocal sound.
“Come Together,” like “Deep Purple” by Tempo & Stevens, plays poorly on many phonographs.
