How much difference does the low Bb vent key make on a Fox 330? I've read both that it isn't necessary and that the low Bb is very flat without it.

Seal up the vent tonehole with a bit of tape to see what difference it makes to the low Bb when it remains closed. The low Bb should be around 5Hz flatter with the vent closed.
I've just serviced a Howarth S10B that hasn't got the bell vent and the low Bb is noticeably flat without it.
I fitted one to my plastic Selmer Signet Soloist as the low Bb was very flat on that instrument.

That explains what's wrong with the low Bb on my Yamaha 441. No vent and very flat. Oboes are tricky!

I was asking so I would know whether to buy one with or without. I don't have one with a vent I can plug to hear the difference.

I don't know about the Fox, but my first oboe, a Cabart, did not have a Bb vent. The tuner thought it was an A. :0 The Bb key was basically useless as a Bb.
I have no dramas getting Bb in tune on my Marigaux with the vent. If I was able to choose, I would get the vent.
