Fender Hi Mass Bridge IV Brass

My Jaguar bass came with the standard fender bridge, yes the one that starts holding the saddles in place only when it gets rusty, seen that i could not wait that long i started looking for Badass (my jazz bass has one since 1998 and its great) but i could not find it, then i have seen this one and ordered it. The bridge weights 250g against the 100g of the standard bridge, feels sturdy and well machined, bright, shiny. The installation took only few minutes, mostly to remove and reinstalling string as the unscrew / rescrew took 2 minutes, direct replacement.
Pros:
the bass was a neck diver but the extra weight in that position made my bass a better balanced instrument.

Every note rings and added sustain

No more saddles moving around

The adjustment screws are very precise and stay where you leave them.

It changed the look of the instrument in a very good way

Low price for what it is really

Cons: none

Just installed the bridge on my Squier Affinity P Bass. Tried it with my old nickel D'Addarios. Every ear is different so not all people can understand the effect of the Hi Mass bridge. But definitely it provides better sustain. Just record samples before and after the installation and see what you cannot hear.
The bridge was direct bolt on replacement, needed a bit of professional setup job though, as, even at the lower position of the saddles, the strings sat high enough to prevent you from setting the correct action. Also, the G string saddle needed a small alteration so that the string could sit exactly where it should above the pickups, aligned between the pickup poles. If it was a more expenssive bridge I would consider returning it, however, with some fiddling at no extra cost the problem was solved.
Overall I am very happy with my purchase, transformed my cheap daily player into a high quality looking and sounding bass.

Really nice heavy brass bridge but a bit limited in saddle height adjustment.

I've owned a 4 string version of this which I fitted to a Mim jazz, but to get the action anywhere near where I liked it I had to shim the neck quite a bit.

It was the same issue with the 5 string version I fitted to my Hb pjr 5.

The base plate is just a little too thick.

But once shimmed and basses set up it's rock steady, weighty but good and certainly for the 5 string it's made it a superb instrument I wanted to get rid of but now can't.

I took it off the jazz as the shimming just became ridiculous. Surely fender should be aware. I only set my basses up to their specs which works for me.
