This resolved a number of issues I was having in setting up my bass. For me it wasn't a simple swap as most of the holes didn't line up perfectly due to the original bridge not being a standard hole pattern. This meant filling two screw holes and drilling more then making the string through holes in the body inline with the bridge. Not a major issue if you have the tools and ability but something to be aware of, my advice is to remove your old bridge first before ordering this to see if the holes are in a straight line.
I am very pleased with the ease of adjustment this gives me and the ultra low string height it allows, I no longer need a neck shim to get my action as low as I like and the spacing seems much more even than on the old bridge.
I have it fitted to a Godin Freeway 4 bass which benefits a lot from this upgrade, tuning is much more accurate and quicker now too.
It's a little pricey but I think it's worth it, my bass is so much nicer to play now !
