Choosing and Using P-Lines™

The best part about PedalSnake is the ability to achieve "only one cable". Not only is this a thing of beauty, but it is the fastest and quietest setup you can have. PedalSnake's P-Lines are the key, as they allow you to get rid of the nasty AC power cord you run to your pedalboard.

You may first want to see the basic idea behind P-Lines, and how they allow you to use only one cable, with no AC power cord.
Learn how to run low voltage to your pedals thru PedalSnake with low-voltage P-Lines. NO MORE AC POWER CORD.
You can then choose whether to adopt the ultimate PedalSnake-Strymon 24V Method, or keep the power supplies you have now.


The 24V Method

NEW ... The easiest, quietest, and smartest way to power pedals. An onboard power supply ... with NO AC POWER CORD.


Keep the Power Supplies You Have Now

If the power supplies you use now work well for you, you can keep them. To do this efficiently, here are some guidelines to follow before purchasing your PedalSnake.

P-Line Basics

The "one cable only" solution, aka the Low Voltage Method, is the fastest, cleanest, and quietest guitar cabling system on Planet Earth. Run low voltage to power your pedals thru PedalSnake.

The Magic of P-Lines

PedalSnake P-Lines (PowerLines) that allow you to eliminate the AC power cord that runs out to your pedal area, by moving power supplies back and plugging them in with the amp. Their low voltage (9V, 18V, etc.) is run thru PedalSnake P-Lines, and you have the ultimate application of the PedalSnake System.
Using the power supplies that you already employ, the basics of P-Lines are simple:

One P-Line for Each Power Supply

Most folks require only 9V for powering their pedals. 9V pedals can often be power chained from one 9V power supply, saving power supplies and P-Lines. If you have pedals that require other voltages, you need P-Lines for those power supplies too. See Pedal Voltages.

Use Dual P-Lines

When you can, use these to save BaseSnake channels and cost. Dual P-Line Pigtails available are MF2, MF2-I, and MM2-I.

White 5wire Channel for Higher Current Loads

Larger Hi Current Pedals should use the MF1-H Single P-Line on the white 5wire channel. This will make a Hi Current P-Line.

See our helpful videos at the PedalSnake Channel on YouTube. Start with BaseSnake and Pigtails, then watch P-Lines and Power.

Work Out Your Power First

It is best to work out your power scheme before you purchase a PedalSnake System.
The goal when designing a power scheme for you pedals is to use as few power supplies as possible to achieve quiet, reliable power. Not only can this save money on power supplies, but each power supply uses a P-Line, so you seek to minimize the number of P-Lines you need too.

Efficient power can be had by following a few simple guidelines:

Power Chain 9V Pedals

Power several (or all) of your 9V pedals with one standard power supply. We are referring to the 9V pedals that draw very little current (the ones with a 9V battery option). Use a power chain cable. Contrary to popular belief, this is easy to do properly, and quietly. See Power Chaining is Fine .


Don't Overload Your Power Supplies

There is a maximum "mA" current rating printed on a power supply. If you have many 9V pedals, you may need more than on power supply and P-Line. See our article Don't Overload.


Use the Power Supplies That Come With Pedals

While not all do, pedals without the 9V battery option should come with a power supply. With few exceptions, power those alone with their supply on a separate P-Line, or with a proper isolated output of a larger supply.

Using Power Supplies with Isolated Outputs

In order to eliminate the AC power cord you run to your pedalboard, you can move board-mounted supplies to the backline, and preserve any isolation you need by running their outputs thru P-Lines.

The number of P-Lines needed with your PedalSnake can be minimized by efficient use power outputs. A good example is shown below that preserves all the important isolations. Note that, contraryt to popular myth, 9V "battery" pedals can be power-chained because they draw so little current.

A Note About Board-Mounted Power Supplies

AC powered board-mounted power supplies do not allow PedalSnake's "one cable only" solution (see Low Voltage Method). A separate AC power cord must run out to the pedal area.

The new PedalSnake-Strymon 24V Method is superior. A single 24V P-Line in PedalSnake powers an onboard 24V-sourced Strymon power supply, and no AC power cord is needed. The 24V can be run throught PedalSnake's low-voltage cabling system.

However, some folks do keep their AC-power supply, and only Replace Amp-Pedal Cabling. In this case, P-Lines are not required.

However, we do highly recommend using P-Lines to achieve "one cable only". Most folks eventually switch to this, because the Low Voltage Method is the fastest, cleanest, and quietest cabling method you will ever experience. We have a 30 Day Return Policy (minus shipping). So you can try it for yourself without risk.

For simple rigs, there is nothing wrong with proper use of discrete isolated Class 2 Transformers (wall warts). We like these because they are the most cost effective, and are totally quiet when used properly. Most simple rigs require only one, and it rarely takes more than 2 to properly isolate a rig to be hum-free.
