Hi,

Good Day

I bought my first Marshall Amp December 2020 but mainly using it at low volume since I live in an apartment and don't want to upset my neighbors.

Recently I cranked the Ultra Gain to 12 o'clock position, Volume 12 o'clock - and started hearing a noise - like a static noice that you hear on old TV. As you increase the volume or gain the noise gets louder too. Clean Channel is quiet even at max gain or volume. 

Is this normal? I used to watch lots you tune review of this amp, and I don't think hearing this on the demo (considering they have mic infront of the speaker).

Any information you can share is appreciated.

Thanks
