Bon Jovi "Have a nice day

Ritchie used a talk box to get that sound, which is something completely separate from normal amps and stomp boxes. I've seen some talk box simulations somewhere around here, but I can't remember who did them.

I'm pretty sure @paults did a few.

The guitar parts sounds big, because they are doubled/tripled. My guess on the actual amp sounds would be JCM800, with enough gain for some breakup in the attack, but not a saturated gain. If you set up the sound for the solo's gain, turning the guitar down for chords may give you the rhythm sound, too.

There are many ways to get that multi tracked guitars sound - you could use one or more of these at the same time:

Chorus, a short doubling delay, Detune are all worth a try.

You're welcome!
