If you own a bunch of guitar pedals, you’ll probably putt them together on a pedalboard. A pedalboard power supply allows you power supplying all of them with a single device, keeping things tide, nice and safe.

Now, why should you consider buying a pedalboard power supply?

Because is not always a good idea to rely on batteries. You won’t like to run out of batteries in the middle of a solo onstage. A pedalboard power supply is a reliable means of providing the electric power your pedals need.

Perhaps your pedals use different supply voltages. Even though most pedals use 9V (DC), you may have some that use different voltages, like 12V, 18V and 24V (DC) or even 9V (AC). A pedalboard power supply have a bunch of outputs with different voltage values.

You also have to take into account that not all pedals can be run with batteries. Depending on the supply voltage they use and their supply current needs, the manufacturer will sometimes provide you with an AC power adapter. What happens if you supply your 10 pedals with their respective AC power adapters? Yeah, you end up with a big mess…

For all these reasons (and a few other i’ll discuss here), a power supply unit for your guitar pedals is a great investment.

Before digging in, there are some basic terms you need to know first.

Some terms you need to know first

Voltage

Voltage is the difference of electric potential between two points. It is measured in Volts (V).

Either AC or DC, any single electric (and electronic) circuit needs a voltage supply to operate. Normally, one of the points is used as a common reference and is called ground. Most of the times ground will be 0V.

Current

When a voltage is applied to any conducting material, a flow of electric charge appears. This flow of electric charge is produced by electrons moving from lower to higher voltages. It is measured in Amperes (A).

Take the gravitational field again as an example. Movement is defined as the displacement of a mass from higher to lower gravitational potentials.

Similarly, electric current is defined as the displacement of electric charge from higher to lower electric potentials. Notice that the flow of electrons is opposite to the sense of the current!

Power

Electric power is defined as the rate at which electric energy is transferred by an electric circuit. It is measured in Watts (W) and given by the product of voltage (V) and electric current (I). Sometimes you may see different power ratings concerning power supply units:

  • Input power (i.e. supply power) is the electric power required for any device to operate. In the case of a pedalboard power supply, it is the power consumption taken from the AC mains supply.
  • Output power is the power delivered to the load connected to its output. If the power supply has more than one output, the total output power will be the sum of all single output powers.

The total output power will be lower than the input power. This difference is given by the efficiency of the power supply: a 100% efficiency corresponds to equal power at both input and output.

Voltage source

Pedalboard power supplies are basically voltages sources. A voltage source is an electrical device that is capable of maintaining a constant output voltage between two terminals, no matter what load is connected to this output.

How are guitar pedals powered?

Most guitar pedals need a DC supply voltage to operate (some pedals like Line6 modelers use AC voltage). When you supply them with a voltage, an electric current flows from +V to ground, allowing the circuits to do their stuff.

Now, how’s this current like? It depends on the circuits. Usually, digital circuits draw higher currents, while simple circuits (like most overdrives) require just a few milliamperes.

In any case, any pedal will tell you how much current it needs to operate. It is not exactly how much current it actually draws (is usually much less), but what is the minimum current that the power supply is able to deliver.

How do you actually deliver electric power to a guitar pedal? Check out this article for more details. In any case, these are the basics:

  • Power supply input jack. Every single pedal has an input jack to connect an external power supply. Although the characteristics of this jack may vary among pedals, there is a sort of de-facto standard: the 2.1mm tip-negative jack and plug arrangement, first introduced by BOSS pedals.
  • Internal battery. When the current consumption of the pedal is not too high, it may use a 9V battery. However, there are some pedals that don’t allow using batteries. This is the case of most digital pedals, such as delay, reverb and modulators. In any case, I find the use of batteries a little risky: imagine you’re in the middle of a solo and your distortion pedal runs out of battery. Now what? Either for a hardcore use of pedals when gigging or for sporadic use at home, my recommendation is to rely on a pedalboard power supply. Just pick the option that is best for you.
  • Input Jack as a on/off switch. It is very common that guitar pedals incorporate a stereo jack for the input plug, even tough the signal path is mono. This is because one of the tips of the plug, when connected to ground, will the pedal to be actionable only if a jack is plugged in. Otherwise the pedal won’t switch on. This is very practical if you use the pedal with batteries.

What is a pedalboard power supply?

A pedalboard power supply is basically a device that provides a few guitar pedals with the electrical power they need to operate.

It is the most convenient way to power supply all the pedals on your pedalboard. Instead of having a bunch of different power adapters (one for each pedal) or use a battery for each pedal (when possible), you simply connect the pedalboard power supply to the mains socket and connect every pedal to it.

But how does it work? It takes the line AC input and converts it to DC. The number of outputs, their nominal output voltages, the maximum current they’re able to provide, and the quality of the supplied power vary from device to device.

As always, the more you spend in a power supply, the higher the quality. And depending on how and when you use guitar pedals, you’ll probably need a good quality power supply.

On the other hand, if you simply want to avoid using batteries and want a pedalboard power supply for using it at home, you may use cheaper solutions.

Now, what makes pedalboard power supply units different from each other?

What should you ask to a pedalboard power supply

OMG pedalboard (source: Effectsbay)
OMG pedalboard (source: Effectsbay)

 

When looking to the pedalboard power supply unit that better fits your needs, you have to take into account the following considerations:

  • Number of outputs. How many pedals do you have on your pedalboard? This is number that you’ll need to take into account, because the pedalboard power supply must have enough outputs to supply them all. If you have a large pedalboard, you may need more than one unit.
  • Voltage of the outputs. Most pedals are supplied by 9V DC. That’s the reason why most of the outputs of most pedalboard power supply units are 9V. However, you may have 12V pedals, or even some using 9V AC (like Line6 modelers). Be sure that the pedalboard power supply incorporate the voltage outputs that match the needs of all your pedals.
  • Current rating. Each output of the power supply is rated for a maximum current. This is the maximum amount of electric current that is able to supply to the pedal. Be sure that the current rating of the power source is higher than the current consumption of the pedal. The current consumption of the pedal is usually specified by the manufacturer.
  • Type(s) of output(s). There are some pedalboard power supplies that have isolated outputs. That means that every output is electrically (and physically) isolated from each other, which prevents the apparition of coupled noise, avoiding buzz or hum. This is definitely the way to go, but this units are more expensive though.
  • Load regulation. The load regulation is the ability of the power supply to maintain a constant output voltage despite changes in the load. This changes may occur when different functionalities are switched in an stompbox, requiring different supply currents. This may cause a voltage drop if the power supply is not well regulated.
  • Supply filtering. The pedalboard power supply transform a high voltage AC signal to a low voltage DC signal. The more filtering you apply to the voltage supply, the more stable the supply is. Cheap units slightly filter the voltage, which can make some pedals not to function properly. This can be even worse if you play in some venues, where the AC mains may present overvoltages and interruptions.
  • Total output power. Apart from the voltage and current ratings of each of the outputs, the unit is going to be able to supply a maximum power overall. Be sure that this total power is higher than the total power required by all of your pedals, when switched on at the same time.
  • Value. You have to valuate how you’re going to use your pedalboard. If you just play at home, to use a simpler (i.e. cheaper) unit should be just ok. Think that the power at the input of the unit is going to be pretty stable. In addition, if you’re not going to take your pedalboard from home you won’t probably need a very rugged unit. Now, if you’re going to take the pedalboard with you more often (to gigs, rehearsal, and so on) you better buy a more solid (i.e. more expensive) unit. And if you play live more often, you do need a reliable power supply, with isolated outputs to get rid of any noise or disturbance coming from the input mains.
  • Size. Size matters. You’ll have to place the power supply unit somewhere on the pedalboard. Due to the fact that the top of the pedalboard is usually very populated with all your pedals, you’ll prefer to put the power supply at the bottom. If this is the case, be sure that there’s enough room to allocate the unit, and fasten it securely.

Should I get a good pedalboard power supply?

You have to balance the previous factors. In general, good pedalboard power supplies have the following features:

  • Each manufacturer has different models featuring different amounts of outputs
  • They have “special” outputs, with higher current ratings and output voltages different than 9V
  • The outputs are isolated, well regulated and appropriately filtered
  • They are able to provide high total supply power
  • They are solid and rugged (and SAFE).
  • Great value. Even though you may find some of them rather expensive, they really worth it.

… And what about cheaper solutions?

Cheaper power supplies come in the form of power adaptors, with a single output that is daisy-chained. You can also find multi-output supplies from Chinese manufacturers.

In either case, use them carefully, when the input mains are safe and stable, and they’re going to supply just a few pedals.

Lower quality power supplies have the following general characteristics:

  • Reasonable amount of outputs
  • Good variety of voltage and current ratings
  • The outputs are not isolated, and both load regulation and voltage filtering are poorer
  • The built quality is lower, and they are less safe to use due to poorer EMC protection
  • Worse value. They’re cheap, but less durable and less reliable anyway

    • Hey Zochar, it depends on how you’re gonna use them. If you need a rugged unit to bring onstage, don’t get one of these. To power up a few pedals at home it could be a handy solution. I’ve using the Caline for one year now at home and it works great.

    • Not at all!! I think that, except for the cheapest cheap Chinese units, the main brands on the market have pretty solid power supplies
