If I were trying to get that sound from a multi effects unit, I'd use a little Compression, Chorus, about 50-60% Distortion and some Reverb.
That's for the main part. there's no chorus effect on the solo...for the solo, use the same patch, boost your gain a bit, take off the chorus and add a nice long delay - maybe 350-500ms.
I used to do that song one in one of my old bands - Ill try to find it and put it on an mp3. We had two
guitar players in that band - it was nice to hold that note at the end of the solo while the other guitar player continued the rhythm part that goes into the next Bridge.
