I think chorus is more common on famous bass recordings, but I tend to like flanger better. Based on your experience and/or best guess, if a band member requests that you put a chorus effect on your bass and all you have is a flanger, what percentage of the time will it be close enough? Thanks.
Unless you dial in over the top jet flange or bearing in a tube sounds, you could probably use a flanger in place of chorus most of the time.
In essence they are the same effect, or at least achieved in much the same way. I have wondered in the past why the control ranges on some pedals aren't extended (longer delay times, deeper feedback) to cover both outcomes. But to the question, I've used flangers that can create passable (but not great) chorus effects on the most subtle settings, but not many chorus that can do useful flange effects, mainly because the longest delay times are still too short.
It's probably the case with most flangers, but the Boss BF-3 can do a very good chorus effect. I don't use it much, but a bass-player friend of mine who plays metal uses it anytime he can live or on recordings, through an LS-2, just to give more dimension to his sound.
It would depend on which flanger, use a short delay with minimum regeneration and you should be okay but if your flanger is a DanElectro Psycho Flange Triple Thick, not happening.
The Ampeg Liquifier was supposed to do both, as well. The chorus was very lush sounding but I did not feel it got to the flanger sound I was hoping for.
Get a decent multi mod and have lots of options of all 4: chorus, flanger, phaser and rotary. Personally, I use a Source Audio Lunar.
Depending in the unit they can come close. The fulltone choralflange is a great chorus pedal and an OK flanger. I personally don't like neither on bass though.
