Pedals electricity

[::XeS::]

How do you guys power up you pedals in studio?
Do you use batteries for everything or do you use power supplies?
My actual setup for guitar is tuner -> TS -> ISP Decimator (sometimes)...
I read in the past that batteries give a cleaner signal when Power supplies add some noise in the signal
What do you think?

I use this. http://www.diago.co.uk/pedal-power/powerstation/

Never had any issue with it, got 4 of my mates into using them as well and they're all very happy with them. For the price, it's a great unit. In fact, it's a great unit full stop.

Their after sales is also excellent. Spoke to one of their guys via e-mail at great length about an issue I was having with a pedal and he was very keen to find out the end result and was very helpful. Mailed me back rather quickly each time too. The issue was the pedal, not the supply.

I try to keep a box of 9v around. I'm sure there must be a high quality power supply available but all of the ones I've seen are pretty poor and often noisy.

I read somewhere about some famous guitarist (or bassist?) who could recognize what fucking BRAND of batteries his tech put into his pedals. There will always be snobs

Everything seems to ef with my signal.

Monitors, cables, guitar shielding, pedal power supplies, crap grounding etc etc.

I used to always use batteries for recording and gigging, because I'd heard they were better, and took it for granted.

More recently I built a mic-pre which runs off two 9v supplies. When I hooked it up to batteries in place of the wall-warts there was audibly more noise.

So clearly YMMV.

I could waffle about the technical factors involved, but in the end it depends on the circuit being powered, the particular PSU / batteries, and the EM environment.

It'd be quicker to just try the options for yourself.

Rechargeable batteries suck, though. Very nasty noise.

Eric Johnson maybe? Ive heard that story attributed to him before.

What about this one? http://www.thomann.de/it/skb_ps_8_pedalboard.htm
It has 500mA output but I don't know if it's enough for 3 pedals. The Diago for example has 2000mA

 

[sprack]

Most pedals are in the 20mA range. You're fine with 500mA.

You could always do what I did- http://www.ultimatemetal.com/forum/equipment/468438-check-out-power-supply-i-built.html

This page confirms what he's saying. Also gives you an idea of what most pedals are putting out. The Diago seems ok to power a lot of other non pedals as well

 

[::XeS::]

Yes 500mA seem enough...hoping it's not a noisy piece of gear

 

[Wolfeman]

It might be noisy.
The only sure way to prevent noise is to isolate.

I think you'd be better off saving a few more quid and getting something a little higher in the food chain.

Amp need to just come with phantom power built in, and all guitar effects should be phantom powered (via TRS cable).

Actually googling around found me this:
