GuitarPCB Fuzzy Bee v2 Build Instructions

Fuzzy Bee v2 (Pump'd Up Edition) Build Instructions
Board Dimensions (W x H) 2.13" x 1.67" i.e.: 54.0mm x 42.4mm. This design will fit into a 1290NS/1590B size enclosure
or larger. We recommend a 125B enclosure or larger for beginners. This board allows you to make a modernized version
of the Buzzaround​ TM​ fuzz pedal and includes a charge pump so that you can use PNP transistors and still share a power
supply with other circuits or pedals.
This board has 9mm PCB-mounted potentiometers, which mount to the under-side of the board. Later in this document, a
Drilling Template will be provided to assist you in drilling your enclosure accurately. If your holes are a little off, and the pots
do not fit, please enlarge the holes with a file or a larger drill bit. Absolutely do not force the pots into the holes, or you
may break the circuit board. You may also use wired pots and arrange them knobs in your enclosure to suit your personal
preferences.

IMPORTANT NOTES

● For the transistors, we recommend GuitarPCB.com matched PNP Tone Bender sets. If you acquire a
Tone Bender set elsewhere, please make sure they are PNP, not NPN, and have low leakage (<.3mA).
● The board is printed showing the correct orientation for a vintage 2n404, 2n1305, 2n1307, etc. If you
use a different transistor, it is ​ c ritical​ that you check your transistor's datasheet and verify the pin
orientation.
● Any charge pump that adheres to the 7660S or 1044 pinout may be used, as long as it has a frequency
boost for pin 1. If you use an older 7660 (no S), you will likely hear noise in the circuit from the charge
pump.
● The board mounted 9mm pots are available at various sources. The model required for this project is
shown at some suppliers with another "1" within the part number, e.g.: RD901F-40-15R​
