The JOYO ZGP is a wide-range voltage input power supply. It is well known that effect pedal hum and unwanted noise is the source of much aggravation for many guitar players. This little unit is specially designed to isolate a power supply's unwanted noise and hum making your pedals sound cleaner and giving you a clearer and more satisfying signal from the guitar to amp. 

The ZGP is capable of isolating the power supplies hum and noise from a 9v adapter which effectively means that ground loops and/or most ripple noises should be a thing of the past.

  • It filters ripple noise from the adapter
  • It provides 800mA working current
  • Breaks the ground loop and offers independent output
  • It provides stable 9V output voltage
  • Reversed Polarity Protection

Power draw

By: on 22 September 2021
I've reviewed this little gem before (I've bought a number of them from AG for my various pedalboards), so I won't comment further in that regard, but I just wanted to add something I've discovered recently, and it's that these ZGPs do add a measurable power draw to your pedal chain, so you need to factor that in if you're getting close to the limits of your power brick outlet. I have an accurate power draw measuring tool (a 1Spot mA Meter), and it shows that a ZGP adds around 40mA. Doesn't alter my very positive view of the value of these units, which are a great solution to noise problems, but it's something you need to know if, for example, you were to use one on, say, a 90mA pedal fed by a 100mA outlet — could push it over the limit.

Only got this delivered yesterday after a long delay by AusPost. Have only used it once and it seems to be ok. Will know more when I use it with more pedals and different pedal settings. Giving it a 4 star only because I need to use it more before I really know what it's like.
