General Notes

The power and signal pads on the

PCB conform to the FuzzDog

Direct Connection format, so can

be paired with the appropriate

daughterboard for quick and easy

offboard wiring
Be very careful when soldering the

LED, diodes, transistors and

voltage regulator (IC3). They’re

very sensitive to heat. You should

use some kind of heat sink

(crocodile clip or reverse action

tweezers) on each leg as you

solder them. Keep exposure to

heat to a minimum (under 2

seconds). 

You should use

sockets for IC1+2, or be super

careful not to overheat. Take

your time.

Snap the small metal tag off the pots so they can be mounted flush in the box.
Positive (anode) leg of the electrolytic capacitors go into the square pads. Negative leg (cathode) of

the diodes go into the square pads.
C11 can be laid flat across the top of the adjacent resistors to ensure plenty of clearance when

mounting in the enclosure. See front cover image.
Pots mount on the back side of the board. You can use vertical-mount pots or just wire up ‘normal’

ones. It’s a good idea to place the pots in their holes in the enclosure when you’re soldering them in

place on the PCB. That way you know they’re going to line up ok. Best way to do it is to solder a

single pin of each pot in place, then do a visual check to see that they’re all sitting at the same

height. If not, melt the joints and readjust any that are off.
If your pots don’t have protective plastic covers you

should place a strip of thick card between them and the

board when soldering to keep them a good distance from

the pcb to avoid shorting other components.
You should solder all other board-mounted components

before you solder the pots. Once they’re in place you’ll

have no access to much of the underside of the board. 
The bottom of your board should look like this >>>>>>
The circuit is very sensitive to input. You’ll have to tweak

the bias and sensitivity pots to get it set just right for

each individual guitar. It’s the nature of the beast.
