MAC - Verified

MAC for MATCH-AC (1590B Okay!)

This is a MATCHLESS / AC30 Emulation.

If you are familiar with OLC MATCHLESS, this is the stripe down version of it.

Tone selection section is striped.

The trace at bottom left of PCB is quite tight. Becareful to avoid solder bridge.

Q1 is MOSFET, BS170 or 2N7000.

Q2 and Q3 are JFET, J201.

SunShine Liquid Overdrive - Pending Verification

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.

DynaRed Distortion - Build Verified.

DynaRed distortion. (1590B Okay).

Dp is polarity protection diode.

IC is CA3130EZ from internsil.

2 LEDs at the top left corner are CLIPPER. Use red LED there.
