The recent thread on amplification and acoustic v. electric made me wonder about amplifying acoustic tone, which I believe is an ongoing quest in the guitar world.
Is there any way to significantly amplify a harmonica without electricity? I think I've seen some classical guitarists use what appear to be large wooden boxes to project to an audience, though maybe these require a large solid vibrating medium like the guitar top. Can something similar be adapted for harmonica? How about some sort of cone shaped device?
I sometimes play with some string players, and my harmonica sounds too weak when unamplified, and too non-acoustic when amplified, if that makes any sense. If anyone has any ideas please let me know.
