Hello,

when nothing is connected to my amp, a MG50GFX from 2022, there's still a hissing sound coming from the loudspeaker and the headphone, turning reverb off helps a bit but when doing a gig and the amp is at 70% volume it is annoying, is this normal for these amps or can there something be done about it?

The noise has been there from the first day I own it but because I played it mostly at home it didn't stand out enough to complain about.

greetz,  Frans
