Some pedal power problems can be fixed by switching to an isolated power supply.
Isolated guitar pedal power supply schematic.
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.
For cable connectors between the power supply and pedals i decided to use 3 5mm stereo jacks inspired by dunlop dc brick which uses mono 3 5mm jacks.
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.
The iso brick boasts 10 outputs making it possible to run a wide range of pedals with noise free dc power.
If short circuited or overloaded this led will turn off.
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 the circuit board i used a thick fiberglass eyelet board and the enclosure is a custom aluminum 14 5x11x5cm box.

Buy guitar pedal power supply 10 isolated dc output for 9v 12v 18v 100ma 300ma 500ma effect pedal with usb port for charging mobile phone tablet short circuit and over current protection cp 04.
In my opinion this is a fantastic power supply that can power a wide range of pedals and each output is completely isolated.
When pedals share the same power output unwanted noise and interference can be introduced to the signal.
This phenomenon is most common in daisy chained pedals.
