I've assembled LOTS of customs now for others and myself, including 2 LZ-GH keyboards and some really dense chunks of metal like Lightsaver V1, and every keyboard does sound and feel differently. But with that said, there's nothing resonating about my LZ-GH. Maybe it's because I always approach keyboard assembly from the angle of picking the parts that make the most sense with each other, which means switches that feel and sound good on a particular keyboard. My LZ-GH with soft Jailhouse Blues is very very quiet and well-dampened. I also usually line the space under the PCB with a dampening mat of some sort, if space allows, which I've done with LZ-GH. To each their own of course, but in my opinion this kit has an excellent unique design, and I love its weight distribution.
