Hey Marshall Forum!
About a year ago I bought my first ever Marshall amplifier; the Silver Jubilee 100W head (with 4x12 cab).
Since I use it mostly at home, I haven't cranked the volume all that much. But when I do, I notice a loud humming noise.
Today I turned the amp on, without having the guitar cable attached to it, cranked up the Master volume (with 0 gain!) and it hummed like crazy.
What could be the source of the humming?? And more importantly, how can I get rid of this awful humming?
The only cables that were attached were the footswitch, FX in/out and the power cable.
Hello Jarnick,
Regarding your 2555X, as it is a 100 watt valve amplifier there will always be a hum when the amplifier is turned up, but if you feel it is excessive it may be down to a faulty power valve. We would recommend that you contact the dealer it was purchased through so it can be checked over for you.
Kind Regards
Marshall Support
Thanks for the info...
