Many of us are willing to go to great trouble and expense to find "that tone". Basses, amps, cabs, effects, strings - the list goes on. But how important is it really, and how realistic a goal is it?
I worked for a long time in the advertising and print industry, and I remember a repro guy who had been in the business for decades once telling me: "there's no such thing as accurate color reproduction". What he meant by that is that you can get in the ballpark, maybe even very close if you have total control of every aspect of the process, but that it was impossible to get it perfectly right every time, and there will always be variables that affect the result in various ways.
I've often reflected over the fact that bass playing is very similar. No matter how much we try to find the perfect tone, it really only gets us in the ballpark. As soon as we play live somewhere everything is pretty much out the window, because there are simply too many variables, and many of them are completely outside our control (this is of course a little different in a recording studio).
I actually don't mind too much. I'm quite happy if I can get my tone roughly where I want it to be, and I personally believe that the ability to get it 80-90% right in most settings is more important than chasing the last 10-20%, which I probably won't achieve anyway, and the audience won't care if I do. But I also realize that there are horses for courses here, and that YMM will, to some extent, V.
So is it crucial for you to have the tone exactly right, or do you adopt a more freewheeling attitude?
Nope, I honestly don't care. I get within the ballpark that I am comfortable with and off we go. Just need it to be not terrible.
