At wits end with my EH deluxe electric mistress

[orange418]

Okay all you aficionados, geniuses, wizards, creators, inventors, and pedal gurus..I really need all you guys' help because I refuse to believe that with all this talent on the forum, not one person can come up with a direction to lead me to me to a possible solution..Seriously,What is up with that? Well anywho.. My dead friend on the kitchen table has an LFO I can hear from the amplifier but doesn't go through to the guitar until i connect the probe from ground to the middle leg of the color pot. Then he sound is controllable from the pots and I can strum  my guitar and hear the flanging effects..I f I push the bypass switch I lose the effect altogether..Why am I not getting clean audio through this pedal? Any ideas..I am completely clueless.. :icon_cry:Any help would be appreciated.. your pal orange..http://www.generalguitargadgets.com/diagrams/dmistsc.gif
