hey guys right now i am learning to play bossa nova. i was wondering if anyone has any recommendations for a specific guitar to play bossa nova.
any nylon stringed acoustic guitar should do fine. I play bossa novas on my Alhambra 4P classical and it sounds great.

I suggest growing out your nails though to get a bit of brightness in your comping and look for books on how to time the rhythms.
