Hi folks, I am trying to get some thoughts on an issue I am having with the elusive and troubling neck movement.
First some backround:
This is a 12 string with .080-.015 strings tune down to B although lately I've tuned it down to Bb.
It has 2 carbon fiber rods as well as a truss rod.
It is a new build and is 6 months old, it is not kept in the case, the humidity is usually around 35 but the weather down here in Georgia is starting to cool down at night.
Last specific, I didn't have the heel cap glued on when I fit the neck and there wasn't contact all the way across the bottom base of the heel but the contact points of the sides/cheeks was very tight (less than .002). When the cap was glued it did not fit flush.
So my questions are, of all the culprits: Weather, string tension , glue failure,etc. or a combination.
How much does the cheek contact of the heel effect the overall stability of the joint?
If the glueing of these contact points is over a French polish (very thin) finish,does that hinder seriously the bond?
I did compare the string tension of baritone strings at a lower tuning compared to medium light guage at standard tuning and feel I am not increasing the tension enough to warrant such a problem in the short amount of time.
And lastly, it is affecting the action as now I have serious buzzing at the 2nd fret.
Just wondering if a neck reset is the only option, how can I avoid this if indeed it is somehow my design failure.
Thanks for any thoughts.
