The zinc stop bar weighs 78 grams, the Faber weighs 28, so between the stop bar and the tuners, reduced the net weight of the guitar by 130 grams. The Nashville to Faber ABR change, was worth about 5 grams of reduction. So reduced by 135 grams total.
So that's about 4.76 ounces, or just a bit more than a quarter pound reduction over all. So from the low 9lbs and into the upper 8lbs range. (barely). But it definitely is enough to feel in the hand and on the strap. It looks nice and plays and sounds nice. Pretty much a win over all.
