Thanks @Al1885 ! Very kind of you to say. This one however, will never be sold! Even if I make 1000 basses, this will always be the first and I will always hold on to it.
I think it depends on what model Squier, I came across a Chinese Affinity that I can bend the back plate with my hands.
The Fender non-badass hi-mass bridge may not be as dramatic.
Honestly it has to be better though. The L-bend bridges never get all that much better than that Affinity bridge. They just look and feel like some kids first-day metal shop assignment. Here kid, take this flat piece and learn how to use the drill press and sheet brake.
I recently swapped the stock, bent plate bridge on my p bass for a high-mass Gotoh 201B-4, mostly for looks (swapped out all the chrome hardware with black). Other than looking better, the only functional difference is it does noticeably help with the slight neck dive the bass had. I don’t notice any difference in tone or sustain.
It’s been a long time since I put a high mass bridge on, however, I always felt like the tone was just cleaner and clearer after it went on. When I upgraded that base, I did it one thing at a time and tried to notice changes. All that said, it was very early on in my base journey, and I could totally be making up all of it. We tell ourselves a lot of things to justify what we pay for things and what we do.
While I don’t think it is the case in the current bridge discussion, changing from old serrated edged saddles to ones with a single slot or groove I think would be an improvement perhaps in tone, intonation and/or sustain.
At least that what I telling myself to justifiy the replacing the bridge on my Sire P5 with an AlBridge parts one.
Here’s an example of a vintage (Fender) bridge with serrated saddles.
