Joyo JP-06 Noise Blocker

The JOYO JP-06 is an isolating element, fitting between your power supply and pedal. Specially designed for isolating the hum and noise from non-isolated power supplies to make your pedals sound cleaner, giving you the signal you actually want! 

If you've noticed some humming or buzzing when using your pedals, the issue could be due to ground loops causing "crosstalk" between effects. This causes other magnetic fields to interact with the current in your power leads. The JOYO JP-06 negates this effect by isolating individual inputs right before the pedal.
