these days, with China around, even new guitars are risky
there's nothing wrong with used gear. many of the good stuff are used. price is not the only factor. you also consider aging and probability -- sa dami dami ng used, im sure you'll find an okay guitar.
in a new guitar, the instrument will still have to learn how to vibrate as one. kaya may binibili na apparatus....yung vibrator
now, imagine this --US vintage guitars are definitely used but many people go gaga over them..
in the net you have used boutique guitars which frequently change hands... they're still good but most probably the did not meet the person's specs.
i've noticed that as years go by, the wood they use in guitars are becoming cheaper and cheaper....farm produced wood. therefore many used guitars are more resonant and woody. newer ones just sound different....which is a deal breaker for many people including yours truly.
then there are the Japanese vintage guitars...if you get to find a good one, it will blow many american standard level guitars...and even the best ones MIJs will eat SOME custom shops and historics....but not the best of them. some lang ha.
so if tone is what you're after, going the used path may be the better path.
but there are people who puts beauty over tone. ika nga ng close friend ko, pag dating sa gitara, gusto niya ng "virgin" at hindi yung kung sino sino na ang humawak.
yes you can find good ones in modern guitars, but you'll have to go through a lot of testing.
