JF-309 Boogie Master

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 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 are interfered and become unstable. To solve this problem, all need to do is to get rid of the ground loop and make sure each pedal work in an independent route and most importantly choose a power supply with real independent output free from ground loop troubles. Well, here is JOYO JP-04 right made for you!
JOYO JP-04 is an isolated power supply available for guitar pedals. It uses a high quality R transformer. It has eight 9V outputs with independent power cable and ground wire, each output is completely isolated, short-circuits and over current protected, highly filtered and regulated, This ensures reliable operation, free of hum and noise. It will provide you a clean and transparent sound.

JP-04

This is the tremolo of the beloved classic tube amplifiers--using the same photoelectric tube circuitry as the trem in those amps of old. Intensity and Rate knobs make it easy to adjust the tone and vibe.
True bypass design minimizes tone loss.
