Just a quirk I found in RS2014, dunno if anyone else has had the same problem, but my guitar never seems to stay in tune. I'll tune it for one song, play, select another song in the same tuning or sometimes the same damn song, and I get the tuning screen again -- but my guitar needs to be re-tuned, usually lower again. It's a little weird, but I usually just skip the tuning. Its the same with all the guitars I've owned; first was an Ibanez SV540 Prestige and I'm currently using an EBMM JP6.
