SunShine Liquid Overdrive (1590B Okay!)
This is build from the scaleton of the original pedal. You'll not get 100% clone from this.
It is an breakup type overdrive.
Gain1 and Gain2 is very interactive to each other.
Transistors are JFET, 2N5458 works best. J201 might need larget trimmer to bias it right.
C10/C11 /C12 are not in the original. It was added for possible tweaking.
VR2/VR3 need to tweak to half of supply voltage or tunning by ear.
