Power Supply For Guitar Pedals Schematics

A simple block diagram of a guitar with a distortion circuit looks like this below.

Power supply for guitar pedals schematics.

Power supply filtering although not present or necessary in all circuits a higher value. Pc boards are available for purchase for many of my projects including the amz mosfet booster mini booster sos overdrive dpdt relay switch power supply pcb and more. Get it as soon as wed sep 23. 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.

Most diy guitar pedal p s will be designed for use with similar components using similar specifications such as lead spacing etc. In my opinion this is a fantastic power supply that can power a wide range of pedals and each output is completely isolated. Usually on the rear of the pedal is a round recessed coaxial jack. Most pedals get their power from a 9 volt supply.

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. 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. Here is a list of the schematics that are exclusive to this site. Distortion pedals are made using a minimum of the two most important things namely the preamplifier section and the diode clipping circuit.

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 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. 4 7 out of 5 stars 20. If your power supply has 18 volts you can use this converter to bring it down to 9 volts.

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. 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. Use a voltage doubler to convert a 9 volt or 12 volt power output for use with 18 volt or 24 volt guitar pedals. 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.
