can "hiyaw" be considered in great playing guitars out of the box? based on a player or buyers preference.
-action is perfect on the buyers "preference".
-no buzzing. have great sustain.
-guitar's pickups suit players preference on tone
-etc etc
if so, i may have a couple of guitars that has "hiyaw" 
hehe
but what about guitars that didnt play great at first, but then after an excellent setup and a few electronic upgrades and changes, can have a chance to have "hiyaw"?
ex: players brings it to lets say their most trusted luthier. luthier performs an immaculate setup/fixes. player plays it. player loved how it turned out. it now sustains great. plays great. sounds great (thru upgrades), etc..
if so, i may have more guitars that have "hiyaw" than i have ever thought. more like all of them have "hiyaw" right after a setup is performed by my go to luthier. upgrades included.
but i may be wrong though in so many aspects.
1. i dont have an idea what hiyaw really is
2. i have poor taste in tone
3. i dont know how to play a guitar
