Pedalboard Power Supplies

I'm thinking of modernizing my pedalboard, after using the same DIY setup I've used for 30 years. As I've crammed more pedals onto the board, ground loops have become a problem. In the old days with only 4 or 5 Boss pedals, I could get away with a common DC supply ground, provided I was careful with my wiring. These days, I've up to 8 pedals (Boss, MXR, Xotic) and it's time to buy my first real power supply.

After the shock of how much they cost wore off, I noticed that very few power supplies have enough power outputs. In this day and age, I don't think 8 pedals is really all THAT many, but there aren't many supplies with eight isolated outputs. So here's my question... do you actually use a dedicated power output for each pedal, or can you get away with doubling up a few pedals on a single output? If the later, I assume some amount of trial-and-error is required to find a setup that is quite.

The pedalboard I have in mind would have (6) 9-volt pedals, a 9-volt tuner, and a 12-volt delay. The only supply I've seen that can supply dedicated outputs for all of those pedals is the T-Rex Fuel Tank, with its scary $200 price tag. (Edit: I just read on the ProGuitarShop website that the Fule Tanks 8 9-volt outputs all share a common ground. WTF? How's THAT ever work?) The T-Rex Fuel Tank Chameleon is slightly less shocking at $150, but effectively has only 5 outputs, so most of my 9-volt pedals would have to be doubled up, two to an output.

I was surprised to find that Voodoo Labs doesn't provided 12-volt outputs. I suppose using a Pedal Power 2 Plus is an option, as long as I use the delay's wall wart to source its 12 VDC.

What's your experience in the real world with pedalboard power supplies?

Re: Pedalboard Power Supplies

I recently got a Carl Martin Pro Power. 8 isolated, regulated outputs, all individually switchable to 12V. Outputs 7 & 8 have some extra juice for the power hungry pedal. It replaces a T-Rex Fuel Tank and is noticeably quieter, because as you mentioned, the T-Rex is basically just a glorified daisy chain. The smaller T-Rex has isolated outputs, but only 5 of them.

This Carl Martin seems solid as a rock. Not sure on price, around $170 I think.

Re: Pedalboard Power Supplies

What is the delay you need to power at 12 volts?

The Voodoo Lab PPII+ has 4 outputs (numbers 1-4) that are switchable to ACA Boss power which is an unregulated 12 volts...if the delay in question is an old ACA Boss pedal you can do it with the PPII+ and even if it is not you might still get away with it.

As for daisy chaining off of outputs on supplies you can do it as long as the total daisy chain doesn't go over the rated current draw on that out...I daisy chain off my Boss tuner which is powered with a PPII+ to power my pedal switcher, the total current draw is about 75mA for the tuner and the switcher and the max draw on that output is 100mA so it's all good.

All of the nicer power supplies are nice, well made units but I will give my nod to the Voodoo Lab...mine has been on my board quite a few years now an dit is w/o a doube the biggest single best "upgrade" I ever made for my pedalboard.
 
Re: Pedalboard Power Supplies

That's a nice looking power supply. It would mount into a pedaltrain with the brackets fine, right?

Not sure, I've got it Dual Locked flat on my board...but I would imagine they've designed it with that sort of mounting in mind. It's certainly doing the job in fine style.

Re: Pedalboard Power Supplies

The delay in question is a TC Nova - it needs 12 VDC and I'm pretty sure requires it to e regulated, so Voodoo's ACA-type outputs won't cut it.
 
Re: Pedalboard Power Supplies

Its funny you asked this question becuz I was shopping for a new power supply too. I'm already rocking a PP2 and will probably get a T-Rex chameleon to power additional effects.

I use only the single outputs - no more daisy chains although you certainly could as long as you don't exceed the mA output.

Also check out the ModTone Power Plant. 7 outputs - 5 of which can be switched to 12v.

BTW - on the PP2 outputs 5 & 6 can be switched to 12v @ 200mA.
 
Re: Pedalboard Power Supplies

I've got the Cioks DC10, great supply. It is definitely able to power a few 12 VDC pedals.

As for daisy chaining, I believe daisying the ODs for instance is fine. You should be careful when daisy chaining time-based effects. Or so I've heard. Someone confirm this?

I ended up with a Voodoo PPII and glad I did. Outlets 5 & 6 can deliver 250mA and it powers my El Cap without any problems. Expensive? Yes but there isn't much in it between it, the Cioks, T-Rex and others.

Tor - interesting point ref daisy chaining time based effects, whilst I haven't noticed any problems I may just swap a few leads around.
 
Re: Pedalboard Power Supplies

I don't remember who here said it first, but you should definitely try and see if it improves anything. I just wired it that way from the beginning, so I can't tell if there's any difference..

Will do, I'm fitting my George L's tomorrow and will make sure my Chorus, Phaser and Flanger have their own supply. :friday:

Aw, it's always nice to work on the pedalboards.. :)

I have a TC Nova Repeater that's powered off the 12V mode of a PP2+. It's perfectly fine. You have to use one of the 300mA outlets.

I'm pretty certain the PP2+ 12V mode isn't unregulated. I don't know why TGWIF said that.

Also, I am fairly certain the TC Nova pedals will work off 9V or 12V. The most important thing is to use the high current line. That's actually true for most digital pedals.
 
Re: Pedalboard Power Supplies

As it turns out, the guys at ProGuitarShop.com answered my question. The Nova needs more current than the PP2+ outputs can supply, but they echoed TGWIF's suggestion about the auxiliary AC outlet on the PP. I didn't know about that until I found some 360-degree pictures of the little beastie today.

Is this the Nova Delay, or the Nova Repeater?

As I said, my Nova Repeater is running perfectly well on the high current output of the PP2+.

I would be very sceptical of the Nova Delay requiring much more current than the Nova Repeater. I suppose it does have that numeric display (which is completely useless IMO), so it may be sucking more juice than its younger brother.
