Easy Order Switching Board - 4PDT Version with Foot Switch & LED
This is a small order switching circuit that allows you to change the order of two external circuits or
internal circuits. Switching is achieved via a 3PDT On-On solder lug toggle switch.
●Switch the order of the overdrive circuits and use in tandem!
●Set the Boost to follow the Overdrive or cascade into it.
●With a Boost following an Overdrive you get an increase in Volume.
●With a Boost preceding the Overdrive you get an increase in Distortion

Using a Common Anode Bi-colored LED as shown above will result in the Red LED lighting when the effects
order is FX – FX 2 and the Blue LED lighting when the effects order is FX2 – FX .
The bi-colored LED can be replaced with two standard LEDs as above Red is FX – FX2 and Blue is FX2 – FX .
Another alternative is to use just a single LED.
When the 4PDT footswitch is in the Engaged position (1) the effects order is FX 1 →FX2, in the Engaged (2) posion it is
FX2 →FX1 If the Easy Order switching board is ulized inside a combo build then discount the top for jacks as shown
above and connect the wiring to the input and output of each circuit board An example would be an Overdrive and
Boost inside a single enclosure You would be able to change the effect order with the flip of a switch
Insert the LED leads into the corresponding pads as shown in the previous example.
TIP: Use a 3v to 5v coin battery to test your LED before installing. Note: 9v direct without a CLR will blow the LED.

Using our 3PDT Wiring Boards in tandem with the Easy Order Switch makes it easy and neat to
share power with other boards. o need for Star Grounding!!
