I am a pedal and DIY freak... I build my own pedals, power suppliers, have a reasonable understanding of how electronics work.
I have some pedal that are VERY sensitive to power supply use; e.g. Germanium Fuzz pedals... and they do not like being powered by my Lithium Ion battery pack - give a terrible noise.
...I tried to build a filter myself; but didn't make a difference
This little gadget cleans things up 100% I really couldn't believe that it work! ...and at the price, very handy to have, just in case of a gig in a venue with an unstable power supply or other electrical interference.

Simple and works well
DominikZ 02.04.2019
I used this to eliminate high-frequency oscillation in a pedalboard where an analog OD and delay pedals were daisy chained to a same power supply with a digital tuner pedal. When connecting the tuner 9V via the Joyo ZGP the oscillation was gone.

Everybody should have one of these

Really useful when you can't remove undesired noises. It works like a charm.

Amazing
JMS Instruments 30.06.2024
These things really work. Had a few noisy pedals on my daisy chain and hooked these up to each individually to find the culprit and it really works. Was doubtful it would at first as everyone always sais it's a daisy cháin issue and nó fixing it etc but it does work! Everyone should have a few.

bye bye hum
yolololo 19.07.2021
I needed this one to hush a tube screamer within a classic setup : single coils + TS + valve amp. I previously had an impressive hum/buzz and this gadget erased it completely. it is the right choice if you need only 1 peripheral silenced and if you are after portability and ease of use.
Great little tool that should fit into your tour case and save the day maybe

This simple thing does what it promises to do. Very small & wimple to use. Everyone should have one in the gigbag.

Well, I can?t see any function for me. I want to try it for a bit hissing Zoom G1on.
But it is cheap and looks well built, so maybe I will find some usage in future for it.

Does exactly what it's supposed to do
Synthy guy 07.11.2024
It fully cleaned up the digital ground noise my Stereo Memory Man was generating on my 4 pedal daisy chain. Works perfectly! (for the very specific scenario of isolating pedals that create noise when powered by a daisy chain).
It doesn't reduce any other type of noise from other sources / issues, but it does what it claims to do.

Excellent little device
Donchov 20.05.2020
I am pleasantly surprised by this little device.
My power supply is standard Thomann adapter, powering 6 pedals and every hiss, caused by not properly grounded outlets is eliminated by only one Joyo ZGP. Highly recommended!
