Joyo JP-04 Isolated Power Supply 4 For Guitar Effect Pedals (JP04 JP 04)Joyo JP 04 Isolated Power Supply 4 For Guitar Effect Pedals (JP04 JP 04) JP 04 POWER SUPPLY 4 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 a parallel connection, each pedal forms a ground loop, which brings the noises from other magnetic fields into the signal path and all the other pedals

Great price, but don't stack multiple wires
Size: 300A
I used this as a junction point on a 1 gauge wire. I added an 8 gauge wire to one side, and the cover would not seat. I had to bend and maneuver the ring terminals to make the cover catch. For the price of the items, if used without any secondary wires attached and interior use only, this is an unbeatable deal.
