  • Guitar frequency testing in the white.

    Posted by Neil Miller on December 10, 2025 at 10:49 am

    In Michael Baskin’s on-line video, he uses a frequency test of a guitar in the white to determine whether to thin the lower bout before finishing. The guitar in the video has a bridge attached. I’m wondering if this is the final bridge or something temporary. If the latter, how do the results compare to the final frequency analysis? I’ve used a bolt-on bridge to do the same, but don’t have enough data points to draw a firm conclusion…

    While not exactly an answer. I can at least add that I’m in the “bolt the final bridge to test” camp. Seems a happy medium between no bridge, and having to finish around a bridge. But I’m no expert on the subject

    On a theoretical level. The primary requirement would be the same weight bridge.
    Glue vs bolts might add some stiffness… you will lose energy to rattling if the bridge is less than secure.
    and maybe wood, depending on how you view the tonal contribution of the bridge itself?

    In the past I tested with a bolt on chunk of MDF as a proof of concept. It got pretty close to the final bridge frequency, albeit with a dull kind of thud (not super secure). So that’s what I’m using as a basis.

    Just my inexperienced 2 cents.

    I would probably blue tape/super glue the bridge in place vs bolts which would change the weight somewhat radically.
