Almost done with my 7 string, but theres some problems left.
I slotted the nut appropriately, set the action, and tuned to standard. When I fret a note, its a sharper pitch than what it should be.
So, I tuned the frets appropriately to their respective notes and it has good intonation without being set up yet. I am able to play fretted notes all across the strings and everything sounds fine, great even, but anything involving an open string is horribly out of tune. Assuming I played an F on my 6th string, the open string would be a much flatter than normal E, so much of a difference it makes anything with open strings sound awful.
I was told a zero fret could help with this, but if I were to install one, would it alter the scale length?
If it does, I may as well slot the freboard for a new nut, fill the bridge holes, and change the bridge position.
This is a 25.5" scale length.
The second problem is one with the input. When you plug the guitar in normally, you have to adjust the cable in order for it to work, and you have to maintain that position. If I remove the input and have the wiring exposed, as in the jack is not mounted to the guitar, and plug it in, it functions fine. Why would this have anything to it functioning or not?
I intend to have a pro luthier/tech take a look at this if I can't figure these out myself.
