I would take exception to this. If you feel the need to drown out another musician, then you are in an adversarial band situation where nobody is going to be happy and you won't be making good music.
If you want to be a super-loud superstar, then forget about being in a band.
When a guitar player drowns out my bass, then I figure my contribution is not needed and I pack up and walk. The only way I'd put up with that is for loads of $$$. Pay me enough and I'll smile and plunk root notes all day while you wank away at top volume.
