wood is wood.
same agathis, damar minyak, kapur, keruing, wotever tree will have wood of different densities at different part of the tree depending on how old is the tree.
its not only the wood. it can also be the how the wood is cut, dried, etc etc etc... too many variables.
plus all the variables on the guitar eg. neck material, fretboard material, fret material, pickups, bridge, nut, tuners yadda yadda yadda....
who dare to be the expert here?
my take is... concentrate on your playing.
leave the wood talk to internet experts like me. :wink:
