I use Zoom G6 and Flamma FS21 at the same time.
With distortion, power supplies behave differently, I mean buzzing and buzzing.
I have: an old power supply, it’s 20 years old) It works the most silently! It is made large and apparently of high quality, it is handmade. But it doesn’t tolerate voltage surges well anymore((
Next comes the AD16E power supply, I have 2 of them. It's a little buzzier than my old power supply (especially if the Flamma is plugged into the G6's effects loop.
I have more(
"RockPower Power Supply RP NT 22 EU", it seems to be stabilized)) Never buy it, it hums and buzzes very much, it's a waste of money if you are a rocker and play with distortion.
And there is((
"Thomann NT 0910 AC/PSA"
This one buzzes and buzzes even more (This is real hell.
My rock band and I are very upset that choosing a high-quality power supply is so difficult (((
Especially in a music store.
From what we bought AD16E is better. Although Thomann support believes that they all have approximately the same quality, and by this they misled us(.
