Zero break angle and it looks like the bridge is in contact with the body/pickguard(that is a no-no). Also, I find having the saddles level will cause the screws to no longer "unscrew". Having them uneven creates that problem as well. Top

It plays well and the unit rocks in there as it should. If i do, I'll use about a 0.070" shim.. i hear that's what they are using currently. It played fine out of the box, so i left it as-is. My SG has nearly zero break angle as well (with stop tailpiece), strung over the stop ala Duane Allman, et al. Top

The bridge post hieght screws don't have an end of travel so thread torque is downward string tension which isn't quite enough. In the video he cuts vibration by raising the bridge, creating extra string tension. But that is at the cost of a less pliable string action. A larger post screw with more thread surface area could help but it's too much work for most people. Years ago when thread glues wern't available and racing cars used wired nuts, a double nut solution was often used. Say you had Triumph Twin motorcycle and the engine mounting bolts kept vibrating lose, then you'd pop on an extra nut and the problem was solved. I'm wondering if that solution could be used in the bridge, a short ballend grub screw meshing down onto the orginal screw or even simpler, a small nut on the bottom of the bridge post. I'm no engineering expert but i feel if you can solve the post screw problem, metal to metal - real torque, Then you can move on to other problems more successfully. Top
