Bought this as a replacement for my Fender Jazz bass. Old bridge was rusted and used imperial size allen keys, so I wanted something new.
Installing was easy, the bridge fit perfectly with the previous holes, and was therefore super easy.
It looks amazing, it's easy to adjust and it has my tuning stability about a 1000 times better. Sustain is also greater than before.
The only reason why this wasn't a 5/5 for me, is that the height adjustment screws are a bit short for my bass. I have raised them all almost to the top, and the strings sit just above the frets. It would be awesome if Gotoh made a baseplate so you could add it to the bridge, but I have been able to find one yet.
Overall, this is a super great choice for your bass. I am actually surprised that this bridge isn't more expensive, really high quality and 100% better sound.
