Bridge coupling question

    Hi all,

    I am in the process of getting a new bass modded. While I was shopping for parts, my attention was brought to the fact that LQ Badass mounting screws are much longer compared to your basic plain-old bridge screw you'd find on a "vintage" type bridge. So I was thinking:

    Is there any relationship between the length of the bridge screws and how well it couples to the body? If I used neck screws (for example) which are much longer than stock bridge screws, would there be any noticeable effect on tone or sustain over the shorter screws?

    Thanks all.

    I'm highly opinionated and extremely self-assured
    Theoretically, yes. In practical terms, I seriously doubt it.

    The most noticable change would be the tips of the screws sticking out on the backside of the bass. Seriously, there would be no audible difference.

  5. Not a chance. Heck, if I can't tell the difference between running my strings thru-body(theoretically the best 'coupling') vs. thru-bridge, then, nah. Engineering know-how says that if you have enough thread runs into the wood to be secure (about 4 or 5), you can't do any better with more. Secure is secure. Sustain? Do you need more sustain?

    The bass plate of the Badass is much thicker than the vintage style bridge so the longer screws go about as deep into the wood as the vintage screws.

    That being said I use longer screws to anchor bridges for no particular reason than I had already bought a box of them.
