[sdiy] Missing Link/URL Needed

[BrightBoy]

Hey Gang!

I know within the last couple of years I ran across a lengthy article 
somewhere on the web that described how to model I believe guitar amp
speaker cabinets, a lot like what the Tech 21 SansAmp pedal does, using
EQ filter networks....

I've searched my bookmarks and done a bunch of Google searches to no
avail....

Does this strike a chord with anyone????

I'm sure it came from DIY guitar FX/stompbox site but like I said I
can't seem to locate it....

Any help is appreciated....

Cheers,
