The amp of the original studio version was an early 60s brownface Fender Vibrolux. Brownface Fenders are far and in between in Kemper profile land. But there is one in a pack from ampfactory - the "vintage & rare" pack. Plug in a vintage sounding strat, bridge and middle PU and it nails the sultans sound. Back then when I got that pack I had the isolated guitar track of the original and did a comparison. It was frightenly close.
Keep in mind that in the chorus (of the song) with THAT signature lick, there is clearly a chorus (the effect) to be heard, likely a Roland. Because of that some people thought Mark used a Jazz Chorus amp. Personally I don't think so. If you listen closely, the chorus fades in as if somebody turned up the aux on the desk during mixdown. Which is probably exactely what they did. The producer of the record was known as a fan of Roland Chorus devices, espacially the Dimension D. So if you recreate the sound, try putting an Air Chorus (post amp) and switch it on during the licks in the chorus.
If you are going for the later versions of that song (e.g. on Alchemy or Live Aid), you need a Shecter instead of a Fender Strat and a profile of the clean channel of a Boogie MKIIb. The sound of the various famous live versions from the 80s is typical for a clean Boogie.
