Or just do what I did and write the stuff yourself, but in such a way that the bass effects are [i]essential[/i] to the sound of the band.
Of course that's not my primary concern when writing material, but it's certainly not vetoed before it's even tried. Even better if you have some way to demo the stuff (none of the other guys read, so this is a necessary evil for me) let them hear it and judge it on its own merits, not pedal-envy.
