The JOYO ZGP is a wide-range voltage input power supply filter, specially designed for isolating & blocking a power supply's hum and noise to make your pedals sound cleaner and only give you the signal you want! It is well known that power supply hum and noise are insufferable to guitarists when using a mixture of analogue and digital pedals with insufficient power regulation. The JOYO ZGP is the cure.

 

Hum and noise may come from patch cables, your guitar, a mixture of pedals but the main source for hum and noise for users is a pedal's power supply system, aka PSU power adapter. Currently, a lot of the 9V adapters on the market are not isolated or even filtered, and their performance is inferior to the isolated power supply about cross talk pedal noise.

 

This noise occurs when several effects pedals are connected to one power supply, each pedal (especially digital pedals) forms a ground loop, which brings the noise from other magnetic fields into the signal path and all the other pedals are affected in a knock-on effect.

Currently, a lot of the 9V adapters on the market are not isolated or even filtered, and their performance is inferior to the isolated power supply about cross talk pedal noise. This noise occurs when several effects pedals are connected to one power supply, each pedal (especially digital pedals) forms a ground loop, which brings the noise from other magnetic fields into the signal path and all the other pedals are affected and become unstable.

 

In the same instance pedals when connected will form several DC circuits which in turn can interfere with each other. This is most noticeable with high gain pedals. The ZGP is capable of isolating the power supply's hum and noise completely filtering out, even from a normal 9V adapter. So say goodbye to ground loops or ripple noise, these headaches are over when you are using the ZGP.

 

Simply connect the ZGP from the output jack of the power supply to the input power of the Guitar effect pedal.

 

The ZGP achieves the following

 

  • Changes the normal daisy chain power supply into a real independent daisy chain output power supply
  • Filter ripple noise from the adapter
  • Max 800mA working current
  • Breaks the ground loop and offers independent output
  • It provides a stable 9V output voltage
