Impedance matching for effects?

[tm486]

Hey,

I have been reading about people's experiences with the woolly mammoth and active basses. Many people advise that it is only worth using with a passive bass. As far as i understand, it isnt a matter of just turning the volume on the guitar down, its an impedance issue.

What i want to know is, could i use one of the devices below along with a 1/4" Mono to male XLR cable to play my active basses through the mammoth and achieve similar results to passive basses?

I am new to effects and impedance and all this lot so simple explanations of why this would or wouldn't work would be much appreciated.


Another possibility, the effects send and return on my amplifier (Ashdown MAG 300), are stated as being 22k ohms on the Ashdown website, would this be a considered a high or low impedance and therefore could i place an effect such as the woolly mammoth within the effects loop, getting results similar to a passive bass.
