Revision 1 of angry duck,

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 :)

note : fair and personal use only

Angry Duck, still inside my mind

This time, I am combining cmos overdrive, First stage is normal preamp buffer but using RAT negative loop, 2 stages in the 2nd section are selectable, 2.3KHz crunch overdrive or CMOS overdrive. After the 1st 3PDT switch, there is another 3PDT switch to feed signal to Ghost Dance Overdrive. Every stage ends, I put 100K trimpot, just in case of voltage overload.

On the last stage, I put contour control before preamp buffer, which originally use to drive tone control section.

But I got question in my head.. which buffer stage I have to use? FET Minibooster using J201 or just normal preamp using NE5532 or RC4558??
