My Manuel Rodriguez c1 has pretty bad intonation and I've been wanting to fix the problem if possible. My High E is about 15 or so cents sharp, almost 20 if I put more pressure on the fret at the octave and though it is subtle, my ears can hear it. It's fairly well set up and the tone is nice, although the problem is similar on b and g. Sharp at the 12th on b and sharp on the 12th at G, although on those two strings it's no more than 5 cents sharp so I can't really tell.
I've done what I can, which is changed the break point of the E string and shaped the nut about 1mm which helped the octave sound like an octave, but the higher I play on the E the worse it gets, naturally. At the 19th fret I'm 40 cents sharp already, although I don't really use that fret at all.
I suspect that the bridge was put in the wrong place? The bass strings all seem to be well intonated and I can live with G and B being slightly sharp but that e? Quite a bother to have really. Can I move the bridge back at all? I've tried changing the strings although I stick with med tension and the issue persists. Likely the bridge being a problem rather than a string
is 15-20 cents sharp considered a lot?
What is your action on this Guitar? If the action is high, lowering the saddle may help it not play so sharp. It's been my experience, with guitars in this price range, that oft times the bridge is put on in the wrong place. In which case, I would get another guitar.
Also, what strings did you Try? And, are you one of these guys that tunes sharp to settle strings in faster, and do you prefer stretch your Strings? Doing both of those can cause intonation problems.
