"Keith Richards’ trippy tone on “Shattered”? Phase 100. The intuitive operation and bullet-proof reliability of MXR pedals ensured that those guitar heroes could reproduce the sounds of their hit records night after night on the road as well as in the recording studio."

In this article, Richards says, “It was down to one little foot pedal, the Gibson [owners of the Maestro brand] fuzz tone [sic]… I’ve only ever used foot pedals twice [the other being an XR delay on Some Girls]… effects are not my thing. I just go for quality of sound… “I was imagining horns, trying to imitate their sound to put on the track later when we recorded. I’d already heard the riff in my head, the way Otis Redding did it later, thinking this is gonna be the horn line. But we didn’t have any horns, and I was only going to lay down a dub. The fuzz tone came in handy so I could give a shape to what the horns were supposed to do. But the fuzz tone had never been heard before anywhere, and that’s the sound that caught everybody’s imagination.”

In this excerpt from his autobiography Life, Keith Richards talks about using a green MXR reverb-echo pedal on Some Girls:

What a lot of Some Girls was down to was this little green box I used, this MXR pedal, a reverb-echo. For most of the songs on there, I’m using that, and it elevated the band and it gave it a different sound.

Based on the description, this is likely a 1970s MXR MX-118 Analog Delay.

Keith Richards began using various MXR pedals starting in 1977. According to Ted Newman Jones, the Stones' guitar tech in the 1970s, both Richards and Ronnie Wood owned about 10 MXR guitar pedals. The MXR M-108 Ten Band Graphic Equalizer Pedal is the only MXR graphic equalizer mentioned in the book "Rolling Stones Gear," suggesting this is the one Richards used.
