Since the main guitar I use is a D-size model from M company, I've mostly used this guitar at home and haven't taken it out much. It hasn't yellowed and sounds better than it looks. It's perfect for fingerpicking. Pickup is welcome, but please do so after payment is complete. I am located in Osaka Prefecture. Of course, I will refund the shipping fee.
