Hey guys, only been playing for a few years now, and about to snag my first fender, a jazz. Its used, but in great condition and besides the strings everything is stock. I was planning in the future on doing some upgrades if I ever come across a problem with everything being stock, and one of the most common upgrades I see time and time again is people putting on a Badass II bridge, which seems to be the holy grail of Hi-Mass fender bridges. The only thing is, other than looks, I don't know what I'd be paying 100 bucks for. I understand they increase your sustain but thats about it. Is the difference really that noticeable and am I really better off upgrading? What are some of the main differences one would notice between a MIM stock bridge and a badass ii? And lastly, what even is Hi-Mass? Is it just more bridge? Idk. Please help me out, I've been curious for a little while now. Thanks in advanced!
