Hello everyone, I've noticed that particularly with my three highest pitch strings on my telecaster the fretted notes at the lower frets are sharp when the strings are tuned to pitch. At around the 1st through maybe the 4th or 5th frets the note is sharp when using my tuner. This makes some of my cowboy chords sound a bit odd. It is a partscaster and the neck I am using is from Warmoth. Is it possible that this is a nut issue? Possibly the nut slots are not cut deep enough? I pretty much just put the neck on the body, intonated the bridge and started playing it, never touching the nut.
