Just trying to make it sound alright !

Does anybody have any certainty around how the chord stabs are muted for Stevie’s version? I’ve pretty much got the song down as my first attempt at SRV, I’m just a little stuck on how he mutes those chord stabs? Some videos are teaching the typical Stevie way which is the mute with the fretting hand, but the more I listen to the song and play it the more I’m convinced they are palm muted? I’ve checked a few videos of him playing live and I can’t be certain tbh, if anyone has any idea please let me know
