Marshal Code 25 Issue


Hi There, 

I have been using my Marshall code 25 since last yr and noticed that when the amp is plugged and NOT turned on. There is an electric current at the end of the cable. It only dissapears when I turn on the AMP. The electric current runs until the guitar when its plugged. I have tried the cable on other amps and it was fine. 

Has anyone experiences this? or is this normal? 

Appreciate the response.

I have the same exact issue. But I finally resolved it by grounding my amp. In my case our house only uses two prong outlets. What I did I bought a three prong adapter with a ground pin outlet provision. I connected the ground pin connector of adapter to a very long wire and connected it to an exposed rebar attached to the house. This solved my grounding issues. On top of that my amp now is silent. No more hum and weird noises. I hope this helps. - Oliver Tejada 10 Dec 2021 at 05:28 PM
