I am certainly not an expert on this, but did go through this recently.
First, there are several detailed threads on this in Jerry Tone. Search “newbie” and you’ll find the collective wisdom of the people who really know.
The advice I was given, was start with a strat and a good JBL speaker and go from there. The JBL seems to be critical, and I certainly love my D120. As I was told this gets you “90% there”.
Amps become more of a debate, but for easy, I had a lot of recommendations for a Deluxe Reverb Reissue. In the end I got a Quilter 101 Reverb. I know there is some compromise there from real tubes, but depending on your needs it’s amazing. There are lots of threads about them here, and some really experienced heads use them (check video from Jerry’s Middle Finger, for example).
After that I get out of my depth - of course you can look into guitar mods, more classic amps (BF twin reverb, MacIntosh power amps, etc). Then the discussion of effects (personal vote for Brian’s Thick Air pedal from IO guitars).
And of course, you then have the small matter of learning to actually play like the man himself
My novice view of a simple place to start....
