---------------------- multipart/alternative attachment This week I went to tune a Bennett-Bretz upright I had tuned once before in 1980. All strings cross the bridge on a stamped metal agraffe that at first glance resembles a supply house bridge repair agraffe. Each agraffe has a termination bar toward the speaking length. A second bar providing the offset fits into a notch on either side of the agraffe. The agraffe is affixed to the bridge by a screw which is inaccessible without lowering the tension and slipping this second bar out of its notches. They seemed fine 22 years ago, but on this visit there were some awful buzzes and rattles which I tend to blame on the agraffes. In the bass, the rattle sounded like a loose bridge, but on sporadic notes rather than a whole section; pressing on the bridge had little effect. As a trial, I lowered the tension on one treble note, slipping the agraffe apart to tighten the screw but am not sure if I got any improvement. Fortunately, the customer did not have high expectations and is perfectly happy with the result of my work! Anyone have experience with these? Bennett-Bretz is a Stieff brand, but every one I have ever seen is a dead ringer for Kohler & Campbell. I assume it was Stieff's low-price line made by K&C and that this was an experiment that failed.
