Title: parachute wah
Post by: Sauerkret on November 17, 2009, 05:51:55 AM
Hello,

I would like to ask what kind of mods i have to do to the parachute wah is i want to tap of the bandpass filter at U2A's output http://www.geofex.com/FX_images/parapedal.gif (http://www.geofex.com/FX_images/parapedal.gif).
do i need to add any components apart from a 2 way switch to go from lowpass (original) to bandpass filtering?


i also would like to ask if anyone has a PCB layout for the 2 band baxandall (active) EQ id like to put that in front of the wah. or would a passive eq be better?

I don't think so, as long as you tap it and provide DC blocking to the output in both cases.
