One Power Supply, two combined 9V pedals

I'm building a distortion pedal with a TS-808 type distortion and a Rat type distortion run in parallel for obvious tonal qualities.  How do I divide the voltage of the power supply between the two?  I'm sure you could just tell me to put certain resistors or other components in place to do it, and THAT WOULD BE NICE.  But, I'd like to know how it's calculated for future reference and experimenting.  I really don't know anything about dividing the voltage.

Any help would be GREATLY appreciated.

You don't have to divide the voltage to power two or more pedals in the same enclosure just connect the V+,Vref and ground where they belong in each circuit and you are done. It's like using a daisy chain power cable but with traces in the PCB.

About voltage division, here is the formula:

Vout=Vin (R2/R1+R2)

Example: for Vin=9V R1=10k R2=10k then Vout=4.5V=Vref
