| Shure SM57 Unidyne III ?? I stumbled across this old SM57. It looks like any other 57, only the sticker on the grill is a little different and says: "Shure Brothers Incoporated Model SM57 Unidyne III", where "Unidyne III" is written in this kinda big "1960's alike" font.
Is this a "copy" or just a really old 57? It sounds good. |
