Princess Rawr v1 – Build Document

Description:Description:Description:Description:

The PrincessPrincessPrincessPrincess RawrRawrRawrRawr OOOOverdrive verdrive verdrive verdrive is inspired by the Catalinbread KATZENKONIG. The circuit is

based around a Tonebender merged with a Rat. This is a dynamic, interactive fuzz where

small interactions with the controls can make a big difference. Nice organic sounds.

• NEW! NEW! NEW! NEW! The MS MS MS MS ExcelExcelExcelExcel version of the BOM is now available on the product page.

With this you can do cool things like sort the BOM by value or possibly make

notes for yourself for easier building/shopping etc.

• Enclosure SizeEnclosure SizeEnclosure SizeEnclosure Size………… This pedal is designed to fit into a 1590B

• TTTTransistorsransistorsransistorsransistors: : : : It is unknown which actual NPN transistors are in the circuit

however 2n3904 seem to work good in the test circuit.

• It is always a good call to solder components from shortest height to tallest.

In this case, you should start with resistors, diodes, film caps, transistors and

the electrolytic caps last.

• The IN/G/9V/OUT pads are a direct match to Rullywow.com 3PDT and Detour

Optical Bypass PCBs..pick some of these cool PCBs up for a super-easy

building experience at rullywow.com

• All pots are designed for 16mm Alpha Right Angle PCB mount. I normally

grab these from Tayda Electronics, however Smalbear and Mammoth have

them as well. I always suggest to drill holes in your enclosure first, and

mount the pots and switch with the nuts BEFOREBEFOREBEFOREBEFORE soldering the pots to the

PCB. This ensures you won’t put a lot of stress on the PCB and everything

lines up nicely.

• 9v/GND 9v/GND 9v/GND 9v/GND pads are included at the top of the PCB for your convenience. You

can use these or not. Helpful if you want to put your DC jack at the top of the

enclosure for example.

• The 1n4007The 1n4007The 1n4007The 1n4007 diodes can be substituted for 1n4001 or whatever 1n4xxx you

may have on hand.

• Be sure to insulate the pots from shorting on the back of the PCB. There are

special pot covers (like from Smallbear or Mammoth) or you may use non-

conductive tape or some other insulating material like cardboard etc.

• Before putting your creation into its enclosure, you should always test it! If it

doesn’t work outside the enclosure, it won’t work inside (I promise!)
