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
