    I like to tinker w/my bass. I replaced the bridge awhile ago and liked the sound/feel, (less wolf tone) before I installed the adjusters. I made these 1/8" aluminum shims that provide a more solid relationship between the 2 bass bridge pieces. Just loosen strings, jack up adjuster, fit shim, back off adjuster, done. These shims took about 15 minutes to make, could be made out of brass, plastic, wood etc. Initial impression is totally subjective kinda like messing w/your sound post. Arco seems louder, slightly less wolf, the A and E strings seem more defined. Pizz maybe a little tighter feel, less loud. I will keep them on my bass for awhile and see what I think as time goes on. For those who like to mess w/their bass thinking they can find that illusive improvement in tone/feel you might want to give this a try. Anyone else tried this?

    I guess you could try it with Maple, too or other hardwood.

    I don't understand the point of doing this - isn't it just another layer between the bridge and the top? What problem is it solving?

    Closer to a solid bridge?

    I think that's the idea. I've seen something like this before. It's clever and simple and worth a try. There ought to be a perceptible difference between this and your bridge sitting on a 1/4" bolt.

    There is a perceptible difference. I've almost eliminated the Ab on D string wolf tone. Arco is definitely louder, the A string is much more solid. I am going to leave the bass this way till the humid weather necessitates an adjustment.
