Hmm, thanks. Well after digging into it a bit, it seems as though a proper "wah" effect is an LPF with a resonant peak at the rolloff point:

Apparently very easy to do in hardware (2 transistors, couple caps, and an inductor), but I'm not sure where I'd find a LADSPA plugin with this particular frequency response characteristic.
Looks like Rakarrack has a wah, and "alien wah" (from Zyn?) and an auto-wah of its own. I'll try those instead.
