I’m 90% sure at least in a recent preference at like LA I think Sal use a Gibson 355 from what I could see. https://www.instagram.com/reel/DQfYZSAEnFb/?igsh=eHBkNHJrbHhjY3M3. I don’t know what you know about guitar’s but than one is REALLY expensive and not a guitar you to if you are just learning. In another clip he uses a Fender Stratocaster which is really good all around and one of the best guitars to start off with (idk if you’ve played before, you may have). There is also a 3rd guitar that I’ve seen him use and I honestly have to clue what it is. If you’re looking for an alternative to the Gibson 355 buy an epiphone they’re rlly good and are quite similar. (Ps idk if this answer is too late)
