About this Joyo JP04 Isolated Power Supply

Have you ever found the strange noises jumping out of nowhere when using several pedals together? The biggest reason that produces such annoying sound is that pedals are connected in a parallel mode. With such parallel connection each pedal forms a ground loop, which brings the noises from other magnetic field into the signal path and all the other pedals are interfered and become unstable. To solve this problem, all need to do is to get rid of the ground loop and make sure each pedal work in an independent route and most importantly choose a power supply with real independent output free from ground loop troubles.

Well, here is JOYO JP-04 right made for you!

JOYO JP-04 is an isolated power supply available for guitar pedals. It uses a high quality R transformer. It has eight 9V outputs with independent power cable and ground wire, each output is completely isolated, short-circuits and over current protected, highly filtered and regulated, This ensures reliable power, free of hum and noise, just clean and transparent sound.

Good little unit

I got this unit because of the isolated outputs. It is a little bigger in physical size then I thought but ive plenty of room in my pedal board for it. It does what it says it does. Much more professional looking set up then an adaptor and daisy chain setup.

This is a really well made product that does what it says. I had the cover off in minutes to see whether it was going to kill me. I design this stuff for a living (military and medical equipment) and I can say it appears to be well designed and constructed. Solid earth in place, and all the mechanical parts fit perfectly. Oh and it also works....

Nice piece of gear

Good value true isolated power supply

The power supply fit perfectly into my Joyo RDB2 pedal board. I've loaded it up using all but the higher powered outlet and even daisy chained a few of the pedals. My pedals are as quiet as if they were running on batteries. The power supply came with plenty of cables and I found it very easy to keep everything neat under my board.
