Not sure what the aim is here. This is an effects discussion on a bass forum so I think you’re unlikely to convince anyone of bass effects’ uselessness per se. 🙂
Sure, there’s plenty of music where effects aren’t needed or would be unwelcome/sound out of place. By the same token, there are many settings where a judicious use of effects contributes musically, even holding down the low end. Thankfully there’s a place for all these approaches. (Most of my gigging has been without effects, but I have managed tasteful use thereof in some settings where they wouldn’t normally be heard much and it went down brilliantly with the audience.)
