Use a voltage doubler to convert a 9 volt or 12 volt power output for use with 18 volt or 24 volt guitar pedals.
Power supply for guitar pedals schematics.
The outputs are fully isolated and extremely quiet and accommodate a variety of voltage and current requirements two 9v outputs at 100ma two 9v outputs at 300ma two 9v outputs at 450ma two 18v outputs at 250ma and in one particularly cool feature two 6 15v variable voltage.

The iso brick boasts 10 outputs making it possible to run a wide range of pedals with noise free dc power.
An isolated power supply i recommend is the voodoo lab pedal power 2 plus click to see on amazon it is seen by many guitarists as the best power supply for guitar pedals available right now.
For example if you don t have any 5v pedals you can just swap the 5v power regulator for a 9v regulator and now you ll have double the 9v power.
Most diy guitar pedal p s will be designed for use with similar components using similar specifications such as lead spacing etc.
Usually on the rear of the pedal is a round recessed coaxial jack.
If your power supply has 18 volts you can use this converter to bring it down to 9 volts.
Browse the free pedal building info in the projects section the lab notebook the guitar fx blog or many of the links in the left column.
The schematic uses a simple power supply circuit converting ac to pulsating dc smoothing it with capacitors and running it through voltage regulators for fixed dc outputs.
Distortion pedals are made using a minimum of the two most important things namely the preamplifier section and the diode clipping circuit.
All schematic symbols shown are those used in guitarpcb schematics and can either be shown vertically or.
A simple block diagram of a guitar with a distortion circuit looks like this below.
Otraki guitar pedal power supply 7 dc output for 9v 12v 15v 100ma 300ma effect pedal board short circuit small pedalboard power supplies over current voltage protection with adapter power cords.
Most pedals get their power from a 9 volt supply.
We created several and we have redrawn some schematics that were already available on the internet for readability or ease of use these needed an easier to read format corrections or part identifiers.
This is usually a 9 volt battery or an external wall wart or multi tap power unit that provides power to a number of pedals at the same time.
Here is a list of the schematics that are exclusive to this site.
In my opinion this is a fantastic power supply that can power a wide range of pedals and each output is completely isolated.
