I don't know if you get Crafter brand instruments in the USA, but I have a Crafter mandolin that sounds okay unplugged and really fabulous mic'd up. It comes at a very reasonable price, too.
I'm not a good mandolin player, but some far more experienced mando players have expressed surprise at the quality and sound of my Crafter.
I have also played a 12-string and a jumbo Crafter guitar and was knocked out by their quality. Wish I could have bought both of them.
(This may sound like I have some commercial interest in Crafter instruments - I don't!)
