Isn't clay-man asking if the bridge can be adjusted for up-bends as well as down-bends using the trem arm , not changing the pitch of the strings via workbench? If so, I can adjust the bridge of my 700 to float, so if it's the same as the 600 it's possible. Having said that, the trem arm on my 700 is almost impossible to make tight enough in its socket for serious use, so I don't bother with it. Love the guitar in spite of that, though
