external input (again)

     Well this isn't the way Mackie would do it but it will work just fine. 
     The thing that the audiophiles would spit on is the noise level 
     (assuming normal op-amps). But if you're going to amplify some signal 
     in order to f*** it up in a modular, this is perfect. Heck make the 
     gain a little higher for some cool clipping distortion FX while yer at 
     it - there's a pot there so you can always turn it down.
     
     Try not to use an old scratchy wire-wound pot cuz the scratches will 
     get amplified too. Hey wait turntable effect...
