I noticed my Marshall Code 25 makes a hissing noise when I play through any of the clean amp models. This hissing noise is clearly audible when I play a note on the low E string. It reminds me of an old cassette tape. This is especially apparent with the cab emulation switched off. On the higher strings there is no problem. Is this normal? The hiss doesn't go away with the noise gate turned on. I have this problem with both firmware versions 1.44 and 1.45.
Bought a CODE 50 two weeks ago and LOVE the tones - great reproductions! But I have the hissing problem as well. Quite noticeable as a chord or note decays. At first, thought it was normal 60-cycle single coil pickup hum, but it is not.
Read similar Posts on the Forum, so tried the firmware update and it did not help. Noise gate not really an effective alternative, either.
Team Marshall, any other solutions in the work Again, otherwise I love the amp and want to keep it.
