Any Advice On a Bass Tremolo?

[Dr.Thumps]

I've been wanting to put a tremolo on one of my basses (probably my jazz bass) for a long time, but I don't know much about them as far as what brand to get, how to install them, etc. Will it effect the tone of my bass adversely? Any advice would be much appreciated. Thanks!

i'm looking at getting one too
i put some research into it and found out that kahler seem to be the most practical seing as they have the least routing required
inch deep just under bridge.
although there is also hipshot bridges which are similar to floyd roses.
but they require so much more routing.
