Pedal technical question

FastEddie

I've a few pedals, Brantone and some from Lumpy's Tone shop which if I put them in line with other pedals do not work.

I don't understand why.
This is annoying as they are such great bits of kit and I'd like to put together a board now I have most of my current faves in my ownership.

Help is required.
Thanks in advance.

P.S Assume you are dealing with zero technical or electrical knowledge and you'll be fine. I'm a dim whit on these matters.

By “don’t work” do you mean “won’t switch on” or “They don’t change the sound”?

How are you powering them?

Seeing that the Brantones seem to be vintage-style germanium fuzz pedals, it's quite likely that they need positive-ground power supplies. You can't use these in combination with negative-ground pedals on the same daisy chain or non-isolated power supply, even with 'polarity reversing' cables - you need an individually isolated power supply.

I have a T-Rex blue power supply.
I need someone to set-up my board. Thanks for the explanation.

The Brantone stuff is vintage styled so they may very well be positive ground. which means your power supply wont work without a polarity switch. However looking at his site it seems the fuzz doesn't have a power input. 

Is it a case that he pedals don't power up or that there is no sound passing?

Thanks Stu.
There is a power input.
It makes a strange sound but the other pedals cut out.

It's the tonebender variant pedal.

Yes, that’s a ground polarity issue and means the power supply outputs are not isolated.

You need a new power supply unfortunately. Switching the polarity of the outputs won’t work.
