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.

By: Woj on 5 August 2020I replaced a BBE Supacharger pedal power supply with this unit: it was half the price and is infinitely better. No hum, clear signal on all outputs. I have varying power needs for numerous effects and there are outputs on this unit to run them all. My rig sounds like a completely new setup. I've only ever had the BBE, which must have been dodgy from the start, and hopefully did not damage any of my gear. Joyo gear has been consistently surprisingly good quality for the price, and I HIGHLY recommend this if you're after a great pedal power source.

The joy of a joyo
By: Roger on 3 July 2019I only recently started down the rocky road of pedals... first came the looper and a cheap single adapter but then I got a gt1 to practice more... but the interference and having to alternate between which unit I was using became too much (not to mention the noisy signal interference from the cheap plug)... so I got a joyo power supply 4. Now I can run both pedals together and enjoy not hearing the electrical interference. The only problem is that I now have the capacity for more pedals... hmmm, which one next?

Great unit
By: Boyd on 22 May 2019I've been using this for 18months now, I use this with my board to practice at home and perform at least 2 times a month sometimes more. Never had a problem, even with my EHX pedals that seem to not like non OEM PSU. Only complaint is it's heavier than some comparable units. Other than that, this will serve you well.
