  2. I like it.
    One might have a closer look at the upper "saddle" member and how it is joined to the wedges. Likewise for the lower joints. They appear guided by rabbets. I'd watch out for vulnerablility from tippling apart if knocked. It looks like you might get about a 10mm adjustment range from it. The pictured bridge appears heftily proportioned. I'm curious about the web between the legs. Why?
    I think much of the success of this item would depend on how good the fit and tolerances are and how well the quality is maintained, good materials, and installation.
    Please let us know what you think Bob.
     
  3. wup. It's because the crotch is thinned so much by the wheel clearance.

    Is this guy reinventing the wheel or what?

    That buttress between bridge legs will do more to kill sound than a sandbag placed on the bass' top.
     
  7. I don't know about a sandbag, but it is a safe bet that isn't going to help the sound.

    Granted it isn't the most informative website I have seen, but I am having a difficult time visualing how it actually works.
     
  9. They say a picture is worth a thousand words, but... basically the bridge is made of 4 wood members. There is the top member that the strings rest on, then the bottom member that include the bridge feet. Between these are 2 wedges. The wedges move in or out, raising or lowering the strings respectively.
    Notice the photos on the website. The larger photo depicts the bridge with the wedges pulled together while the the wedges are spread apart in the smaller photo.

    In my most convincing Arnold Horshack voice: "Oww, Oww Kaaeyy."

    I can see the seams now that I know what to look for.

    If it is equally effective as far a tone goes as the other (two adjuster) I like it better. It appears faster, easier and less likely to get crooked.

    This disassembled photo may help. Interesting concept, though there are lots of pieces and joints. The feet are separate, screwed to the legs.

    Well...
    that's some pretty lame bridge wood.
     
  13. Bob - If you have a gram scale, I'd appreciate knowing how much this bridge weighs.

    Maybe I'm missing something, but it looks like the wedges move in or out without independence of each other. How do you raise one side and not the other? It appears you have to remove the bridge to get at the set-screws for the feet.

    You cannot change the angle of the top, both sides come up and go down evenly. The feet screws are only accessible from the bottom.

    The maker (called me today) says the volume is good, and players have reported an improvement over other adjustable bridges. I haven't yet had the time to fit mine to my bass, so I have no opinion at this time. It is crafted very well.
