power supply for fx pedals question

[Louie Angulo <louie.angulo@googlemail.com>]

Hi gang,
would it be safe tu use something like the the fuel tank 
juicy lucy

http://t-rex-effects.com/Default.aspx?ID=94&ProductID=PROD8&VariantID
(which puts out  5X 12v dc of 300ma for each output)

for the 
following pedals:

adrenalinn (normally requires 9v dc 500ma)
tc
 harmony G (normally requires 12v dc 500ma)
tc VT create (normally 
requires 12v dc 500ma)
EH micro POG (requires 9,6V DC 200 mA)

so as 
you can see: 
the adrenalinn requires more ma than the usual 9v dc 
pedals,and it does not run on batteries would it be ok then to use the 
12v for it?
the tc harmony G is 12v but requires 500ma (more than what the juicy can
 provide per output)but i can use a doubler cable to use 2 of the 
outputs of the juicy to use a total of 600ma
that leaves me with the 
tc VT create
and the EH Micro pog,this one does not take batteries either would it be
 safe to use the 12v dc?
ive been told some 9v dc pedals take 12v dc 
without any problems...
cheers
Luis
