'allo! The reason I'm asking is that I'm pursuing a career in pornography soundtracks and have been eyeing both the EHX Superego+ and the 105Q Cry Baby. Since the Superego+ provides a built in low pass filter and supports an expression pedal, I'm wondering whether this could be used to emulate a bass wah. As I understand it, a wah is a pedal adjusted band pass, and a bass wah would reasonably be built to retain more low end and be closer to a low pass, right? A dedicated wah would of course provide more control and could be run along another effect from the Superego+, but would there be any significant tonal differences?
