It’s been going around guitar circles that for stop-type tailpieces, you should lower the tailpiece all the way down and then insert the strings into the front and wrap them over the tailpiece and across the bridge, rather than threading them straight through from the back side. The theory is it reduces the break angle over the bridge and lowers the tension of the strings. This makes them easier to bend and having the tailpiece sitting tight against the body increases sustain.
I wanted to try out this trick so when I had a reason to remove and restring one of the strings on my Gretsch, I thought it was the perfect opportunity! Unfortunately, as you can see, I think this gives a little too much break angle change!!
