Again, according to White, the bass bridge must invariably be 
connected to the other bridge(s). He also warned against too 
many ribs weighting the board down and deadening it's power of 
molecular and undulatory vibration. Apparently, second 
guessing what the little molecules are thinking isn't anything 
new either.

I seem to be doing everything wrong.
