Sign in to disble this ad
So as we all know there is no problem sticking a battery clip on a daisy chain and powering say 4 pedals via the standard boss plug and one using a battery clip ok. Problem arises when you use 2 battery clips on the same daisy chain into the same pedal say it is 18v so the solution to this is get another power supply or get something isolated like the Voodoo Labs.
What has never been made clear is that if you have 2 power supplies can you daisy chain off both of them say you have 9 pedals 1 is 18v so you are using 1 output from 2 power supplies daisy chains to power that and then using 4 on each power supply to power the other pedals.
Hopefully this makes sense as I'm trying to find a good way to power my Mutron clone.
Or I recently saw this 
Easy to access battery compartment that just links via battery snaps to the pedal.
Cheers

In other news, I bought a '69 P bass

For anyone struggling with the concept, I drew up a little diagram. 
So, would it be possible to connect a battery snap to the mutron (or pedal that needs similar power) on the same daisy chain that is powering OTHER pedals?

Congrats on the bass I'll swap you for one very shiny button, some fluff I found under my bed and a half eaten mars bar.
You pay postage of course

Cheers for the info!

You'd be able to daisy chain off the one that gives out +9v I would have thought..
Yeah good idea TaySte, let me know how it works.

Never saw such a thing in a pedalboard.

If you then intend to daisy chain to other pedals, you must ensure that you don't inadvertently create a second ground point. If you do have two grounds, when you connect signal cables between two pedals on different grounds you will short circuit the two grounds, shorting one of the batteries and everything will stop working.
This arrangement is good for when you have a mixture of positive ground and negative ground pedals. But, positive and negative grounds are not indicated by connector polarity alone - so be careful when you're experimenting!
