I was looking for a little more sustain and after some discussion with Rick regarding his bridge,I was convinced that the Naimish Bridge was what I wanted/needed

We'll let Rick himself explain it...in his own words (as copied and pasted from one of our many correspondences)

As to what you can expect sound wise? An improved fundamental as well as an increase in overtones, the overall result being a fuller sounding note, no matter where it's played on the fretboard.
Also, better harmonics, and the elimination of any dead spots up and down the neck. This last point was an unexpected surprise when I installed the very first proto-type on a late model Fender American Jazz bass. You should also notice a slight improvement in sustain.
Although some modern bridge designs have come a long way in overcoming this last problem, I can't help but think that there is something inherent in the set screw string height adjuster designs that simply can not address the afore mentioned fundemental, overtone, and dead spot aspects

So far,the bridge is doing exactly what he said it would do.

My favorite aspect is string height adjustment...simple,effective and easy.
One screw....simple
Worst aspect...well,in all honesty,the worst aspect has nothing to do with the bridge itself...
For me it would have to be the cost.
$160 US turns into roughly $200 Canadian....which is a fair chunk....considering I only paid $500 for the bass
Now that it's installed ($20 more) I think it's money well spent....still a chunk,but well spent.
Installed on my bass is a heavy duty,solid,simple bridge which I have NO DOUBT will not fail me

Thanks for a great product Rick and I'm one pleased customer
:)
Peace Ed
