Boss / Behringer Pedal POWER

[Lodewijk5150]

I wonder which powersupplys works for the BOSS PEdals such as OverDrive/Distortion or a Behringer Noise Reducer?

The batterys are for 9V but I don't know a shit about ampear and the other stuff, what shall I look for in a store?

A "One Spot" will work great, and you can buy one of the extension cables so it will power four (or five?) other pedals. They're much better made than a Boss adapter (which are notorious for crapping out) and have a longer and use a higher quality cable.

If you're good with electronics, research a simple power supply made from a 7809 power regulator. I built a rather simple version with couple filter caps and it produces a rock-solid 9v for 4 pedals. I wired up a few of the 9v battery terminals to the +/- and hooked right onto the battery clips of the pedals ... worked great.

Here's a page which explains power supply design with the 78xx ICs in some detail:

The only trick with this is that most of these supplies will introduce a small amount of switching noise. For example, my DOD chorus pedal produces a lot of noise on ANY AC adaptor so I always run it on battery yet my DOD digital delay runs great on any relatively regulated 9v DC. go fig.

Could also try an unregulated design with just a 9vAC transformer, diode recitifers, filtering and a load made up of a LED and resistor (to see the power on). Might still be a bit of noise ... unsure though if different rectifiers would exhibit less or more noise.

eh, power supply design is an entirely differnt thread.
Good luck, though.

Just buy a good power supply.
The more amp, the more pedals you can power.
I think a boss OD is rated 300mA.
If you buy a power supply rated 1 A (that is 1000mA), you can power up to 3 pedals (300mA x 3 = 900 mA < 1000mA).
