Hi. I just bought Marshall 1959 HW and it's constantly humming when it's on. I have Wizard Modern Classic Amp and ENGL Powerball 2 and they don't hum like that when ON. Is it normal? Also when I strum a chord very loud mechanical noise going out of the back. Check the video I shot to hear how both issues sound:
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.
