Well, don't tell Bootsy Collins, or any other funkateer bassist for that 
that filters won't change their sound! The deal with resonant low-pass 
is that they aren't just rolling an unamplified cutoff frequency around 
... the 
highly amplified (dialable) resonant peak will take whatever harmonic is 
in it's
proximity and boost the hell out of it. You'll hear a difference once 
done some dialing. With bass you may want to choose to slightly distort 
input signal to boost those upper harmonics. I believe there's upper 
structure in undistorted bass signal though which will filter just fine.

Sure if you that's the sound you're going for ... It's probably going to 
be a 
whole lot more dramatic *and* simple if you just run the signal through 
4-pole and get a distortion (Fulltone Bass Fulldrive 2?..) in front of it.

These filters can *increase* the amount of low end in your signal as well 
decrease it. Cutoff from 40-200 hz boosted to the ceiling could seriously 
the building! 

If you read the reviews on Harmony Central about the Lovetone Meatball, 
many of 
them say that the unit actually increases their bottom end as well. I'm 
not a 
bassist and don't play one on TV either, so take this all with a grain of 
Our list-mate Steuart Liebig is a Meatball owner though and might be 
willing to 
add a few bass specific comments about *that* product...
