There's a 1970s (I'm not sure of the exact year) Guild nylon at a local music shop that's out for about $500. Being mostly an electric player I'm wondering whether its worth it or not.
Why did that happen??
do you like the way it sounds and plays?

if yes: then yeah, it'll probably be worth it
if no: then no, it won't be worth it

If you knew the exact year and model, I could give you a good idea of what it's worth.
