All the different guitar books, CDs and DVDs tell you of different ways to tune your Guitar. I am currently tuning by ear (having music experience), the 5th fret string method, pitch pipes and a fairly good automatic tuner yet can not get consistency.

When the automatic tuner says it is in tune the pitch pipe and 5th fret thingy implies it is not. In the end I tune it so it sounds right but was wondering about advice on what is the most accurate and which i should trust the most (i assume 5th fret thingy as it is the actual guitar, but any advicewould be helpful)

Thanks
