I have a 1972 Harmony Sovereign H6303. It's a nice little guitar. Solid spruce top, solid mahogany back and sides. Ladder bracing. Nice neck. I love it's small concert size. No cracks, the original finish is in really pretty great shape.
BUT...It definitely needs a neck reset. I don't think it is worth having it done professionally. It doesn't seem to me the guitar is worth putting that kind of money into. But I do like the guitar and would be tempted to attempt it myself.
Should I? Shouldn't I? What would you do?
I don't want to ruin it, that is for sure. I've watched a few videos on the process and I feel confident I could get the neck off. But getting it back on straight and solid seems like that could be a challenge.
