Confused..... power to Fulltone '69 Fuzz

simonbeckwith

finally found a lovely sounding fuzz pedal that is perfect for what i want (Fulltone '69 Fuzz). I knew it needed a reverse polarity adaptor due to the nature of the fuzz so purchased a Diago adaptor as i am running a Diago Powerstation.

With the adaptor plugged straight in to the Diago Power Station the pedal powers up fine. If i run the rest of my pedals and add the rev.pol adaptor into the mix for the output to the fuzz, the fuzz wont power up and it cuts power to the rest of my pedals. If i unplug the patch cables it seems to power up the board but as soon as they are plugged back in it powers down the board again.

i am running 8 pedals in total

tce polytune mini
boss oc2
fulltone 69 fuzz
mxr phase 45
source audio eq
bearfoot red rooster booster
way huge echopuss
tce hof

im positive i have enough power to power the board from the powerstation.

seems like it is something to do with adding the adaptor in to the mix with everything else plugged in.

as i said, the fuzz works perfectly when i run it by itself

any ideas other than buying another power supply?

i can video the issue if needs be??

A grounding issue I expect... can you just use a battery? The pedal will likely have a very low draw so a battery should last ages assuming you disconnect the input.

Thats what im doing at present, not the end of the world but annoying

Hey mate,

I think it's because the '69 is reverse polarity you need to use an isolated power supply if you intend to run other pedals.

 From a quick google the diago doesn't look like it's isolated!

So you'd either need to run just the 69 on its own, or on it's power supply, or use a battery or get an isolated power supply.

It's because the pedal ground polarity is reversed, not just the connector. It's positive-ground, so you can't run it on the same non-isolated power chain as negative-ground pedals no matter what cable you use - it shorts out the power supply if you do.

Perfect - that makes total sense, cheers all! Best start saving for a bog boy power supply!!

Use a battery, it will last for years on a fuzz like that

Back from the dead thread...........

I have a Trex Fuel tank classic - is there an adaptor i can buy that will work with the Fultone 69?

The orange cable is reverse polarity, but iirc, the only isolated inputs on the Classic are 12v, so not sure if it will work.

Maybe a battery only for this one. I would rather not but if the pedal won't work with the Trex then it's needs must
