Don't know, depends if the reason is the venue or the bassist's setup. The opinion is so vague.
I can answer using your own words:
I've never seen a bass player (a good one) who does not know about the venues aural impact on the band's sound/tone, and on the sound/tone of the bass guitar.
In short.
Lucky you if you are happy/if you care
only how you sound (your bass) close to your amp, but...
NEVER, ever tell your opinion "that the venue/environment does NOT matter" to any, more or less knowledgeable Music industry representative - a musician/sound engineer.
Remember, the VENUE (a small bar, a big hall, a stadium, etc...) acts as YOUR SPEAKER box.
2- Never saw a bassist asking for opinions in the audience. They pay a soundguy for that...
Here is another interesting thing from my experience.
(Just one of numerous points about the sound engineer's job, issues...)
1.In some cases, there is a "fighting" going on between a musician/bass player and a sound engineer.
(Any sound engineer is a complete world full of the sound engineer's Aural vision, music taste, preferences, job requirements, etc...)
A bass player (most usually) cares about the bass tone/sound, while the sound engineer must think about lots of things, and listen to so many complaints from vocalist/s, and other musicians.
2. I have NEVER seen a musician/bass player (serious) who says, "I don't give a damn how my instrument sounds."
3. I'm getting tired that some of our TB members tend to see something else - not what JimmyM wrote in his post. JimmyM has NOT started walking around tables/audience and asking the audience opinion/s about his bass tone.
Here is MY personal opinion.
If I have a friend in the audience who knows about Music, Sound, etc... - a musician - and I respect the person's opinion - I WILL listen to the person's opinion.
Anyway.
I think you are fighting some (internal) battle about something.
You have your opinion - ONE opinion among MILLIONS of Musicians' opinions - I have nothing against it.
I have MY opinion - ONE opinion among MILLIONS of Musicians' opinions - I have nothing against it.
P.S. Please say hello to Jeff Berlin, and get serious about your bass lessons/questions.
