1. Therefore you've dismissed out of hand everything I said.There's a bunch of problems with this frame of thinking.
1. You are a guitar player. That ain't a bass trombone you're holding.
2. By saying "pretending to be," you're implying using effects or soloing is something a bass is not meant to do but a guitar is. This is simply a bias; while no one may ask you to solo in a rock band, they'll look at you funny if you don't know how to take one in jazz,
3. You're assuming effects are increasing your lowest fundamentals. This is not the case with tons of effects- lots of them make it even lower.
4. Even when using effects were taking a solo that raises the range of your instrument for a time, the only way the song or the band would fall apart is if the song or the band as a whole fail at making solid music. Otherwise, no groups or musics without bass players would have songs that held together. And the vast majority of music throughout history has had no bass guitar and got by just fine.
It's pretty simple- if you use an effect or go for a solo in an appropriate place and the song falls apart, then either you're doing something wrong, the rest of the band is doing something wrong, or you both are, because there's other players and bands out there that can do it.
2,3,4 ???? I'm talking about the mud that comes with a bunch of time based effects slurring note attack.
But mostly I think the disagreement was about #1
