Yes, and for some reason I thought we were talking about autowah's, where
the cutoff is driven by the signal amplitude. Pre-coffee I'm afraid.
If you want the effect to sound meatier, try adding in a little bit of the
source signal processed with a highpass filter at the same cutoff as the
bandpass.
Also throwing in tube simulators before and/or after the filter will add
some more harmonics.
The single band parametric makes quite a good wah bandpass and you can
feed back some of the output into the input to get resonance.
Just play about with it really ;)
If you want to make it sound more dynamic try splitting the signal with a
comb splitter, modulating the cutoff frequency and processing the two
outputs differently before mixing them back together.
