    Default New CA bridge installed on my Eastman 615-WOW !

    Got my mando back from my friend Ray's luthier shop yesterday after having a new Cumberland Acoustics bridge and bone nut installed and I have never heard this mandolin sound so good ! I always felt it was bit lacking in the bottom end and suffered from what I think a lot of import mandos do and that's thin, trebely sound due in large part to poor set up and mediocre bridge construction. Well all that is a thing of the past now as this new CA bridge has increased the volume, sustain and clarity of the entire instrument. The notes sing and ring all the way up the neck-it's fantastic. As a working musician I demand a lot out of all my instruments and now when I stand on this thing it pushes back !
    Thank you again Steve at Cumberland Acoustics for such prompt service and for such a wonderful product. I'll will be a customer for life.

    My friend got the bridge to contour with the top so tight you can't fit a piece of carbon paper anywhere under the feet ! It feels like the top "pops" now way more than it used to

    I just replaced a failing bridge with another inexpensive one. My plan was a CA, but I couldn't afford it at the moment. After going through the trouble of fitting this bridge, I'm hardly excited to do it again, but I do want to upgrade at some point.

    Does the CA bridge have a larger foot print then the stock Eastman?

    Yes it does, slightly. The feet are a little wider apart and thicker in dimension from front to back by a mm or so. The main difference I've seen is the tightness of the threads on the posts and the saddle shaft id tight, tight, tight to the post as well. Very well made bridges.
    If you stop and consider the importance your bridge is to the tone of the instrument, it's well worth the few extra dollars spent, IMO...

    Another thing to consider. One of the other recent strings was dealing with "leaning" bridge saddles. Part of what causes that is the clearance holes in the saddle being a little oversized allowing the saddle to rock. On the Cumberlands that fit is tighter than any others I have messed with. Steve is great to deal with.

    Got one ordered. Fitting it should be a learning experience for me. Looks like lots of good info out there so it shouldn't be rocket surgery.

    Cumberland also sells a bridge fitting tool that is easy to use and works quite well

    Not to hijack the thread, but has anybody tried Cumberland's ebony archtop guitar bridges? As recommended as the mandolin bridges? Thanks!

    Well I finally got around to it. I like it. Only took a couple hours total once I got started. With the bridge lowered as low as it goes it is still a smidgen higher then the stock set up. I could take it off and sand more but I want to play it for awhile before I make anymore adjustments. Fits well except one corner. I would say I have at least 95% contact. I highly recommend a jig for sanding, I can imagine trying to hold it and keep it all square. All in all it worked out well and I would say go for it if your on the fence.
