why dont....?

[seamus bass]

bass multi fx units have the cool fx guitar ones do?

slicer
leslie emulation (i have the rt-20 its rad)
envelope filter

reason i say this is, i have the opportunity to get the boss gt-8 guitar pedal off one of my guitarists, is there alot of low-end loss from this? is it particular fx only that make it lose the low end? or...

Is there a multi fx unit that has more than my gt-6b and i just havent seen it?

The reason there is no bass-specific version of the pedals you mentioned is because there doesn't need to be one. They work fine with bass. I only have one bass-specific pedal out of seven on my board.

i sorta thought envelope filters had to be specific for the bass frequencies

Your GT-6B does have an envelope filter effect. Boss calls is "touch wah."
