Absolutely remarkable!!

conlondf 30.11.2021

I couldn't believe that this thing works!

I am a pedal and DIY freak... I build my own pedals, power suppliers, have a reasonable understanding of how electronics work.

I have some pedal that are VERY sensitive to power supply use; e.g. Germanium Fuzz pedals... and they do not like being powered by my Lithium Ion battery pack - give a terrible noise.
...I tried to build a filter myself; but didn't make a difference

This little gadget cleans things up 100% I really couldn't believe that it work! ...and at the price, very handy to have, just in case of a gig in a venue with an unstable power supply or other electrical interference.

Clear signal

JPeneda 27.01.2025

Solved a subtle digital noise issue in my signal chain.

I have two pedals daisy-chained with a single 9V 1,5A power supply. Both of them have digital processing and every time one of them was engaged and activated the small digital screen, a subtle but still noticeable digital noise could be heard.

Using this noise blocker in one of the pedals supply chain was the solution I was looking for.

Does what it's suppose

boring guy 13.02.2025

Reduces the noise very well. Just too bad that I can't use it with my boss gt1000 core (by far my noisiest pedal of all when in an environment with a lot of electronic devices), as it's not rated for that amperage.

Simple and works well

I used this to eliminate high-frequency oscillation in a pedalboard where an analog OD and delay pedals were daisy chained to a same power supply with a digital tuner pedal. When connecting the tuner 9V via the Joyo ZGP the oscillation was gone.
