whats the difference between necks made out of a certain amount of peices?
It depends. A scarf joint at the headstock makes it stronger, and 2 or 3 peice necks are more stable than 1pc neck as long as the the joints were well done.
i think htat it has something to do with the sound but im not entirley sure. i think its like how jumbo frets are lifted off the fret board is another piece? am i wrong?
