Well it took me a while to find a sound I liked out of it that wasn't all duck quacky, but I like what I'm getting with that setting.Just to show how long it's been the one song I always had to drag the 5 along for was Right Said Fred "I'm Too Sexy..."
I have the DOD Envelope Filter and I've been eyeing that Digitech Bass Synth Wah because it seems like it can do what the DOD can and a whole lot more. The DOD is great and you can get really usable auto wah sounds (not always a given). I haven't really heard a good demo of the Digitech's auto wah (demos all seem to focus on the bass synth, so I wasn't sure if the Digitech might end up sounding gimmicky after a while with it.
