Q about wah-wah pedal

jazzius II · 16th January 2004

can anyone tell me?:.....when you press down on a wah-wah pedal (like a Cry Baby), does the filter open or close?

I don't know if this is a trick question but I'll jump in anyway

When you press down the filter opens - and don't forget to open your mouth in sync with pressing - we guitar players have an unwritten code of conduct about this: it must ALWAYS be done...

cheers....i'm trying to use my Andromeda as a rather large wah-wah pedal......i've hooked up a CV pedal to it (it has external inputs to its filters)......

.....anyone know what kind of filters wah-wah pedals use.......bandpass?.....frequencies?...

(will try the mouth open in sync technique ASAP)

the wah wah sounds more like a peaking band pass filter than anything else so i guess a resonant band pass with your andromeda will do the trick, the sweep might be too broad to accurately emulate a wah wah, maybe you might need to limit the range of the sweep...

Cheap and crappy sounding.

A wah pedal uses a band pass filter. as far as i know the q setting remains constant - im doing a bit of dsp etc at the moment and looked a small bit already into things like this - like mario said limit the range of the sweep, tweek a bit of resonance and you shouldn,t be far off.

Far as i can remember... like i said. down is swept forward not wider.. anyone knows otherwise fill me in!!

Definitely.
Mashing it all the way down with your foot can yield frequencies that will make a dog's head explode.

... oh to be back to the nights on stage in college covering Voodoo Chile (slight return).

jazz,

How do you like your Andromeda? I'm considering

So If Jazzious II programs his Andromeda to sweep, does he still have to move his mouth?

Just use a parametric EQ and sweep between arround 250hz-2.5khz or so.

I like it a lot!.......the sound is super-fat.......it's got some mad features........it's a bit buggy (software)........it's deep!......it takes a long time to really know it inside out........
