Can I get or where can I get flat wound strings for classical guitar?
The best place to get strings in my opinion is juststrings.com. They have everything haha. If they don't have flatwound classical strings, nobody will...lol
You can get polished strings which are intended for recording, but I'm not aware of any true flatwound classicals.
