    Hi all, got a query for any 70s Japanese bass aficionados in the crowd. I bought an old Aria EB-3 copy recently, and I'm looking for an intonatable 2-pt bridge to replace the original, non-intonatable bridge with. My question concerns the spacing, diameter and thread spec of the body inserts that the bridge is fastened to in its "as-is" state. I'm looking at putting a Supertone replacement on the old beast, and need to know if I'm going to have to do some reworking to do the install.

    Thanks for your time. Here are pix... IMG_20160529_090411. IMG_20160529_091912. IMG_20160529_093901.

    If you go on ebay and look at some of the Supertone bridges for sale, some of the sellers put very detailed pictures of the measurements. It helped me.

    You just need to measure from the outside edge of one bolt to the inside edge of the other to get the center to center distance and convert the fraction to decimal.

    OK, my spacing, with bride on and strung, as-is, is 3.175. The Supertone's is 3.26... I may have to do some shop work, but when I get a minute I'll unmount the bridge and have another look.

    In these pics you can clearly see that one hole on the Hipshot is oblong adjustable with a Allen screw in the side of the lobe to assist intonation. The bolts heads are not a tight fit in the recesses. It should be no problem to file the holes to gain .085" clearance you need.

    No. Just observant I guess.

    Well you've been helpful man, I appreciate it. My hands have been pretty full and it would've taken a good bit longer for me to have pulled it together.

    Canada, eh?
    I have a shaller 460 new in the box I bought 5 or 6 years ago with the intent to put in a project bass, but never got around to. They were used to replace for Gibson 2 point bass bridges, but with nice adjustable string spacing, intonation, etc. way better than that Gibson 3 point in my pic over there <---.

    what i have is just like this one: http://www.bass-guitar-museum.com/uploads/bass/8/280138419378-1.jpg

    if you are still looking for a 2 point upgrade, I could sell it to you for a reasonable price. pm me if you want me to dig it out and measure it. might be the 460a model, it has been a few years since I looked at it.

  17. Assuming your dimensions are correct, and the center distance for the Supertone is .085" wider than the Aria, the small Allen screws in the Supertone (and probably the Schaller as well) will bear off-center on the posts by about .042" each. That may be enough that you can't use the Allen screws at all, with the possibility that you'll never achieve proper intonation.

    That's not a foregone conclusion; it may work OK but it's something to keep in mind.

    Thanks for the point there. I played over the weekend though, after more or less adjusting intonation by moving the wood uni-saddle to hit the E and G strings in their sweet-spot, and it seemed to be adequate. Taking into consideration what this animal is, I think I may be alright without the better bridge...
     
  19. I agree. If it's working OK then I see no need to fix it. The 2-point bridge works OK, but it's just OK. Not stellar. I have one on my '68 Gibson EB0. Again, works OK; just not as nice as a 3-point bridge.
