So when I got my Sadowsky, I saw no slots in the top of the bridge. I assumed that meant no quick-release string feature. Today I finally change my strings, and am grumbling about how I have to thread the strings all the way in or out through the stupid little holes. I then noticed larger holes. I think "well OK, the strings slide easier through the larger hole". I get to the D string and the ball end slides all the way through the hole as I'm wrapping it around the tuner. Then the light goes on: DUH, this is a quick-release bridge after all, it just works sideways from the ones I'm used to. Sings: "I am so smart... S-M-R-T..."
