Banjo Bridge Wood Comparisons

Sound measurements with just a few banjo bridges of matching weights and designs but different wood species, using rather simple apparatus and protocols, support two widely held notions: 1) Different wood does sound different but 2) not very different. In this respect, bamboo and mahogany did not perform radically differently, nor did walnut versus spruce. The observed small differences were sufficiently complicated as functions of frequency that no account in terms of simple physics seems likely.
