Power Supplies & Daisy Chains (PP2+, Burkey, Etc.)

[Adoom]

Hello lovely people.



I ask of your learned wisdom once more.

Question:

I recently picked up a Burkey Flatliner Pro, and it has a bunch of isolated 9v outputs. Some of my thingybobs will need individual power supplies apparently, so I assume I can use some kind of daisy chain like cable into some of my less power hungry units like the Fuck, Freaker Wah and Tim? As long as theyr'e all 9v center negative connections with a reasonable enough mA draw?

This'd leave me more or less able to run everything I need to from the Burkey, including some niceties like the Tremolessence at 18v.

Yeah, you can run a daisy chain off an outlet, you get 200mA on a single of those, or 28 Fucks. Usual daisy chain rules apply, i.e. some pedals like it less than others and will get noisy.

I run a few pedals off a 100mA outlet on the Burkey SIX without problems.

[Adoom]

Beautiful. Yeah, just trying to make sure I 'splode nothin'. But good news all round. And the mA of each one I daisy shouldn't all add up to more than 200ma, I assume? Thanks for the help dudeski.

I think the most important thing for daisy chaining, if you have noise, is to separate the digital pedals and any analog pedals that have a clock or timing frequency or oscillator. These pedals will be the ones that will cause problems for you in a daisy chain.. their separate clocks can cause annoying noise called heterodyning plus these kinds of pedals are always high current users that need their current fast and don't like to share current.

It's worth experimenting with though and you won't hurt anything by trying.. some guys daisy chain lots of digital pedals and fancy analog ones and have no problems and you might not either.

The Freaker Wah may need it's own output, I know that mine does. That's because it's a clone of the Tychobrahe Parapedal, which is positive-ground and won't work on a daisy chain.

Hey Ryan! Excellent advice. I'll be messing about alright, but knowing these little tips are the key to making that an expedient process!

On a seperate note: Seriously, that Tremolessence... I'm currently testing it out after loops running into a seperate amp, and man... honestly. Superb. I literally dropped and broke a glass slide I was using when I was running it with guitar, into a Memory Man into my older amp and got one of the most glorious sounds I've yet heard from the instrument.

Love it. And you. ULTIMATE HIGH FIVE.

Thanks man, I'll look at that and see if I need to use any other cables. Does positive ground mean center positive? If so, you may have saved a damn pedal. I haven't plugged anything in yet, but I had that hooked up with a normal 9v cable. Been running it with a battery until now!

Basically agree with this.

I'd tend to recommend to daisy chain your dirt, boosts, wahs, etc together. Not just because they're generally fine with it, but they use so little power you'll basically be wasting an output if you only run one. Not too many dirts will even be 20mA, and that's if they use really bright LEDs.

But, yes, it'll be totally fine so long as they have the normal 9V power supply. Center negative isn't actually a requirement. They sell adapters for that, if it's just that the jack is reversed. But if it uses positive ground, it won't work 'cause the power supply will short.

Word.

Actually no, it's something different. Most circuits in use nowadays use the negative battery rail as the ground. But some of the older vintage circuits use the positive rail for ground. When you put one of these on a daisy chain with a negative-ground circuit, it shorts out the whole chain. So they need to be on an isolated power supply.

Thanks Adam! Really glad you're enjoying the Trem!
