Small Clone Depth Switch - What Exactly Does It Do?

[theundeadelvis]

Howdy people! I'm curious about the depth switch on the Small Clone. As some may have read in this thread: http://www.diystompboxes.com/smfforum/index.php?topic=85053.0 I've been trying to fix this guy for weeks. Well I finally have it where the bypass functions properly, and when the pedal is on, I get un-effected guitar with the depth switch one direction and loud buzzing with it in the other position. I though this might be a clue towards what's wrong with the pedal. Thanks!

Basically, it does what a rotary "depth" control does on most other chorus pedals, except it has two presets, rather than multiple settings.

So does the switch select between sending the signal (coming from pin 1 of the LM358) to ground or to pins 1,3,3 of the CD4047, or am I reading the Tonepad schematic incorrectly? Thanks again!
