Zombie Chorus

Original design by John Hollis, this version has been modified slightly to have a second vbias network specifically for the LFO IC with same value resistors as per Mark Hammer's suggestion in an attempt to solve the ticking problem some people have experienced.

Tweakers may want to add a Chorus/Vibe switch, and if so you can do this by switching out the 10K resistor directly to the left of IC3.
