I just swapped a brass bridge with brass saddles to a slightly higher mass steel bridge with steel saddles, but while the tone definitely got brighter with more clank, grind and bite, and the strings also sustains longer now, that could easily be contributed alone to the fact that I changed the old half dead round wound strings that was on my bass before to some brand new fresh ones in the same instance. Is there any consensus of what difference in tone different bridge and saddle materials contributes to and how big an impact different bridge and saddle materials actually have on the tone? In case there is what are the tone characteristics for each material then, and also is there any difference in how they contribute to sustain? As in steel vs. zinc vs. brass vs. aluminium vs. whatever other metals a bass bridge might be made of. Of course given that the same basic bridge design is used, just made from different materials.
