Like I have always said from Day One, it doesn't matter what the haters say. The fact that they have an issue with bass tremolo systems is their problem, not ours.
There is this really terrible culture within electric music that there are "guitar" things, and there are "bass" things. What a load of crap. It's ALL music. Show me what marble stone tablet has carved in it "thou shall not use a tremolo on bass". It doesn't exist.
I wouldn't care if Jaco himself were to rise from the dead, and pontificate about how bass tremolos are not correct. He would be WRONG. Not saying that he would say such a thing, and in fact, he might very well have gone that route had he lived long enough. My point is that, it does not matter what other opinions are. What matters is YOUR opinion.
