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.

Works well, but very tall

By: on 13 December 2021
I have 6 mini effects pedals and the NUX NMP2 Footswitch connected. Even with everything turned on, there is no hum. All power cables are provided, but I had to buy the patch cables separately. With a height of 55mm, the power supply itself is significantly taller than I expected. Not an issue for me, but I doubt it would fit underneath a lot of pedal boards. Overall, exactly what I needed and I'm happy with my purchase

I 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.
