Mike is using a Strat with a single coil (which is going to sound a little brighter because it has more high end treble) & less gain on the amp.  You can turn down the gain & bass & turn up the treble.  You might also turn the guitar volume down a little.  Those humbuckers add a bit of gain.

Those are the differences.  But really it's close enough to just play & learn the song!  Sounds like you are strumming in time & having fun.  Hope that helps!
