Weird thing on what I'm guessing is a Wilkinson 3D bridge?

    Hey everyone, so I'm looking after a friend's 5 string bass which has a Wilkinson bridge on it. I couldn't see any sort of model number on it, but from some image searching I'm guessing it's some form of 3D bridge.

    I'm trying to adjust the action, but I'm having trouble with one of the screws on the A string. It seems to be blocked somehow by another screw mysteriously protruding from the side of the screw hole. Here's a picture:

    It might be a bit hard to see clearly, but the treble side action screw hole of the A string saddle has something blocking it. I can't tell what it is.

    Would anyone know what this is and how to fix it?
    Thanks :)

    Not burred out grub screw? ie rusted / wrong size Allen key used
    If so I would say use try a small screw driver after using WD40 or such if it fits in to grub screw head.I would even recommend taking the saddle off bridge and soak in wd etc before trying any thing
    Another way would be if the screw is rusted & is pocking out I would even try with a pair vice grips etc screwing it all the way out

    Is it the end of the intonation screw? wilkinson weird_1.jpg
    Forgive me, I'm not at all familiar with 3d bridges.

    I think your right I would say that the grub screw been removed due to intonation screw too long

    Just an FYI...when you get ready to replace that bridge, Babicz bridges have the same footprint.

    Unfortunately the string spacing is too narrow for a Babicz bridge... it's barely 16mm. Possibly even 15.
    Also, what do you mean by "footprint"?

    I'm not familiar with them either, no worries. But yes, that is the trouble spot.

    That's not the only problem with this bridge either. The anchor holes are so high up that if you set the action to a reasonably low point, the break angle is pretty much entirely lost, so the string rattles around in the saddle.

    This bridge sucks.

    If that bridge was my 6 year old son, I'd immediately march his dirty butt upstairs for a shower!

    Seriously, it needs a cleaning. All the little rust bits and chewed up screw bits and accumulated grime is bad for the threads and will make adjusting more difficult. De-rust and clean. And those grub screws will be easier to assess if they're clean.

    'Footprint' meaning the space taken up by the baseplate. Most bridges will be smaller, but Babicz will cover the entire area left behind by the Wilkinson.

    But now string spacing...that is indeed another issue.

    • What the heck is a grub screw?
    • (Edit: I googled it. Never heard that term before.)

    As far as the break angle, be sure the neck relief is set correctly. The straighter the neck, the higher you can set the saddles.

    If the intonation is correct then those saddles are one hell of a way back - look at the B string, the spring is completely coil-bound.
    It looks as if the whole bridge should be mounted further back on the body to me....
     
  12. Yeah, it would be a lot easier to adjust everything, if it wasn’t so rusted.

    There's no play left in those saddle springs. I would loosen those saddle screws a little bit. I bet the ends of the saddle screws are up against the grub screws. (Which, by the way, means intonation must be pretty extreme with whatever strings are on it.)

    I know anecdotes are not data, but fwiw I had one of those Wilkinson bridges on a Warmoth 5-string fretless bass I acquired 20-something years ago, and in addition to always feeling just slightly uncomfortable when I had to do palm-muting, the low B & E strings always sounded pathetically anemic. I changed the bridge to a Hipshot Type A, and holy crap, the low strings sounded huge!

    So I'm inclined to agree with @PlayItAway :)

    But even if it was an awesome bridge when new, that one looks like it's well past its expiration date. Time to cut your losses, methinks.
