[LAU] Wah update

Just a quick update on the wah research. A friend owns a Dunlop "Jimi Hendrix Wah", which says it is the "Original Thomas Design", by which I assume they mean to claim it's the same design as the Thomas Organ Wah, formerly Vox. This website's describes the frequency response as a lowpass with a resonant peak: http://www.geofex.com/Article_Folders/wahpedl/wahped.htm So here is what JAPA says it does (and I believe JAPA more than some random website): When fully closed, it's a bandpass, with a VERY high Q! http://restivo.org/misc/lowend-jimi.png But, wait, when I open it up, suddenly it becomes more like a highpass, but with a lot of resonance: http://restivo.org/misc/midrange-jimi.png When it's fully opened, it's definitely a highpass, but with a helluva peak: http://restivo.org/misc/high-jimi.png So, not only is the opposite of what that article says, but it's also kind of non-linear. I'll poke around the various LADSPA plugins and see if I can find something nearly like this. Another guitar-player friend has a different wah (IIRC, either a "Cry Baby", or a Morley), and I'll see if I can run his through this and see what it comes up looking like. -ken
