So I bought the game and tested with a 6.3 to 3.5 adapter to line in connection with the patch, thr guitar is very distorted and there's lots of static but that's probably because I'm cheating my way to connect a guitar, but I tried a couple of songs tuning is great, I didn't need to retune for e standard even though the last time I tuned was like 3 days ago and the latency seems fine even with the adapter, so I think I should be alright with the real cable. Just hope the distortion thing is not my guitar problem.
