OGS Maple

Old Growth Submerged Maple Bridge Inserts


AMT is now offering premium OGS [Old Growth Submerged] maple reso bridge inserts made from select quartersawn maple which is centuries old and has spent many years submerged under the cold waters of Lake Superior -- where natural aging combined with the action of anaerobic bacteria present in the lake have substantially altered its physical and sonic properties.

This wood's fine annular growth ring density [typically 20 - 30 lines per inch] far exceeds that of most modern maple, and indicates the tree it came from experienced very slow growth... resulting in smaller and more uniform cell size for increased stability/strength/rigidity/resonance.  IMO this unique maple produces exceptional sounding reso bridge inserts.
