"If you think that the bridge is glued down because the strings pull on it, think again. the string tension would pull the bridge off the top of the guitar long before you tightened the strings to pitch."

The strings definitely pull on my Lowden's bridge - it's pinless and the strings don't go through the top. They're steel strings, and they haven't pulled the bridge off the top of the guitar. It's the glue that keeps it there.

The same is true of other pinless-bridge guitars... Takamines, Flambeaux etc.
