Isolated power supplies?

[TRBboy]

Hey folks! 

 

I'm considering buying an isolated power supply for my pedal board, as my Boss ODB-3 seems to have a lot of background noise (not to do with pedal settings, just a high pitched noise) which I believe is due to me running it off a daisy chain supply. 

 

Just wondered if any of the 'budget' ones are any good or not? Surely an isolated power supply is an isolated power supply? 

 

Thanks,

My first suggestion would be to slap a battery in it, disconnect the daisy chan from it, then check to see if the noise has gone away. I’d suggest this just to avoid buying a new power supply only to found out the pedal had some kind of fault.

 

Boss pedals tend to play really nice on a daisy chain, so my gut tells me it’s another pedal causing the issue, even if it’s the Boss unit that’s presenting the noise.

 

Assuming the batter does away with it, most isolated power supplies should work for you. Not all are created equal though, and some of the more expensive ones (like Cioks) really do an amazing job of filtering out noise and protecting against various issues, as well as being able to run each outlet at different voltages.

 

That said though, many cheaper ones will do fine for you, especially if you don’t have a huge pedalboard or multiple different voltage requirements.

Don't get fooled. Most low cost "isolated" power supplies are not really isolated. The isolation they speak of is that each output has its own short circuit protection.
