Hi, I just bought a Brice HXB 6 string bass. I'm going to do some upgrades to it. The bass has a nice quick release bridge on it already. According to the website it is die cast. I kind of like to keep it but I relly like the sound of Hipshot Brass bridges.Aluminum not so much. I don't know what die cast is? I think Badass bridges are from die cast. How is it different from Aluminum or brass in the way it resonates?
