As the title says, how picky are you about tuning/intonation? How much does it matter? Do you just check the open string or open and 12th fret…and additionally 5th fret? How about the first fret, because from what I have seen, it shows neck issues real good ? Also where do you draw the line and how do you check? Clip on tuner good enough, pedal, quantum light diffracting particle accelerator? On a clip on tuner that has the green/red lines to show you how much you are off, what is acceptable and what would be perceived in a normal humanoid ear?
