The Baby Will PCB is back in stock.


The Baby Will is a PCB simplified version of the legendary Marshall 18 Watt 1974x circuit. The circuit we laid out on a circuit board is known as the LiteIIb. It's capable of tone from clean jazz, crunchy blues, to raunchy classic rock. Crank up the volume and you'll be in AC/DC Back In Black heaven.

The following demo has the volume and tone controls up full. All the dynamics come from the guitar's volume control, and you can hear exactly how the amp responds:


The magic of the LiteIIb is its simplicity. With only a volume and tone controls, you won't spend the night fiddling with the amp when all you want to do is shred all the new licks this amp inspires. You can learn more about the Marshall 18 Watt LiteIIb circuit over at Versions 1.1 and 1.3 of this board sold out quickly and we have now released an improved version 2.3. Version 2.3 is the same circuit, but it includes an additional filter stage in the power supply, better heater trace layout, and better component selection, which makes for a great sounding amp with a very clean noise floor.


Terry named this board the "Baby Will" as a tribute to his grandson, William. William was born in September of 2008. Although, he has no idea what we've done, we hope our efforts will leave a mark in the annals of history. The quality of these boards is superb. With the construction features listed below, this board will take plenty of abuse and is sure to stand the test of time.

  • 1/8" thick board material instead of the usual 1/16"
  • double sided copper layers
  • 2 oz. copper layers
  • full board ground plane
  • plated through holes
  • ventilated socket mounts
  • detailed artwork indicating component number and value
  • RoHS compliant

The boards have a green solder mask with white silkscreen layer for the component labeling and artwork.

Simple and Affordable

The Baby Will was developed under the fundamental principles of Simplicity and Affordability. The simplicity of the LiteIIb circuit and the affordability of a PCB package. It's a PCB! Can we make it any simpler? Yes we can.
