I agree and I meant to touch on that idea with my last little comment, but if you're new to the genre the clean, american football tuning tapping ala TTNG is still a new sound, and there are plenty of fantastic bands like Battles, Tera Melos, Physics House Band, etc. etc. doing something fresh. If you notice, I didn't really call out Good Game as ground breaking. I wasn't really sure if OP was looking for totally fresh sounding guitarists, or just very technical music that's different sounding than djent so I touched on both even if I prefer the former. I think the important takeaway is that literally any genre gets stale if you go too far down the rabbit hole so just got check out something else when it does.
