Re: power supply for fx pedals question



Hi Luis,

It sounds like this is probably not a good solution for your pedals. If a pedal requires 500ma and you only give it 300... you are under powering it and might even damage the power supply. The reverse is usually true though.. in that if a power supply is capable of giving say 1000ma and you only need 300.. you're fine. In that case the pedal will only draw 300.  On the volts side.. sometimes you can get away with things like this in the short term and occasionally you might even find something "desirable" about it (think: lo-fi) but it's probably not good for either piece of gear.  For example, I know some analog pedal makers like the sound of dying 9volt batteries in their fuzz pedals (meaning... the batteries are probably giving out less than 9 volts). And.. I know some analog compressor pedals tend to have more headroom if run off a 12volt supply instead of a 9 volt. But.. with the amperage you need to supply the minimum the gear is looking for (or more). It looks like the Lucy is capable of combining two 300ma outputs into a single 600ma output. So.. that should help your scenario, but then it might not have enough outputs for everything. 

Hope that helps!

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
