I remember when I got my first pedal. It was the same Boss TU-2 tuner that I have today. I really only played acoustic guitar then (see this post for more about that). I used a battery for it. Then I got a Line 6 DL4 (again…the same one I have today) and needed to power it so I got the power supply. When I finally started playing electric, I bought a Fulldrive 2 off eBay to go with my tuner and DL4. I suddenly needed a little more to power my pedals and wasn’t really sure what to do.
Powering your pedals is a big deal. The way you power them can determine how you sound and your tone…and if your pedals will fry or not. You spend money on your pedals to sound good, but if you’re not powering them right, you run the risk of them not sounding good. I’m by no means a pro when it comes to electricity or powering pedals, but I’ll share what I’ve learned.
First of all, there are a few things that matter a lot when powering pedals. First of all, is AC or DC power. Most pedals will use DC, but some require an AC adaptor (Whammy and the M9 are the only ones I’ve had to use this on I believe).
The next big thing is voltage. Different pedals require different voltages to power the pedal. The most common you’ll see is 9V or 12V, but you’ll occasionally run into some other stuff. If you don’t give a pedal the right amount of voltage or too much, it will either not turn on or fry the pedal. Check the box/manual/sticker on the pedal or online to make sure you’re giving it the right voltage.
The second big thing is milliamps. Some pedals require more milliamps than others and if you don’t fulfill this it can really bite you. For example, when I first got a Micro POG pedal, I supplied it with 9V but only at 100mA when it requires 200mA. It worked fine almost always, but occasionally something to pop and it would start squealing through my amp uncontrollably (of course, right in the middle of an intense, worshipful moment too)! When I realized what the problem was, I was able to fix it but it was a big deal.
Another thing is the tip connector for the pedal. I believe most pedals require a standard polarity tip negative/barrel positive jacks, but some require a tip positive/barrel negative jack on the pedal.
Honestly, if you use the power supply that comes with each pedal, these aren’t issues you need to think about. But if you the power supply that comes with each pedal, then you’ll have a huge power strip on your board taking up a ton of space!
There are a few options for powering pedals. Here they are:
- Standard Power Supply – You can use each pedal’s own power supply it comes with and plug them all into a power strip. This will work and sound alright, but it’s not really neat and will be hard to travel with.
- Daisy Chain – When I first made my board, I used a daisy chain. You power your tuner or another pedal that has an input power jack and an output jack. You can plug in a daisy chain cable in the output to power other pedals off the power your first pedal is getting. This is a cheap and easy option, but can create a lot of noise in your chain and you can also run into problems powering pedals with different power requirements.
- Multiple Pedal Power Supply – With one of these, you send power to the base unit and use multiple outputs to send to the pedals using connector power cables. This has kind of become the standard of good tone. There are multiple kinds of units you can use for this. I use Voodoo Labs power supplies, but I’ve used a PedalGear.net Juicebox. There are plenty of other kinds that are great. The tricky thing with these is making sure that you’re getting AC or DC power, the right voltage and the right milliamps.
My advice is to get one of these multiple pedal power supplies, but take certain measures to make sure you’re giving the right voltage and milliamps for each pedal. With some of these newer pedals like the Eventide and Strymon stuff, powering them is more difficult, but most power supplies are coming out with stuff that can handle these. I know this is the more expensive option for powering pedals, but it’s worth spending the money to make sure your pedals sound right.
