Revision 1 of angry duck, 

Mods :

1. 1st. stage replaced with cmos opamp, operated in linear mode, flexible gain control.

2. 2nd. stage clone of Ghost Dance, combined with cmos buffer, my basic idea is  to get quacky lead.

3. 3rd. stage linear cmos opamp with fixed gain

4. 4th. stage is a tone control adapted from Marshall shredmaster, changed on clipping diode to 1N34A, all Vbias removed and connected to GND.
5. 5th. stage is a contour control
6. 6th. stage is an anti sucking device

Bias on 1st. stage can be ommited, because seem not too effeective and hard to control on overload condition. maybe need to add resistors to GND and 9VDC power line.

All pots body have to connected to GND, to remove unwanted noises.

enjoy :)
