Hello, excuse my english. 

I just bought a new dsl40cr and i'm very happy but i am experiencing the known problems that this amplifier present when change the channel through the footswitch along with having the FXLoop ON.

In several forums like marshallforum.com there are quite a few people who have found the same fault, which leads to me think that is not a random failure in some amps but something more like a manufacturing defect. Some people have already contacte with the Marshall staff so i understand that Marshall is aware of the problem. The question is whether they are going to appeal to these units so that the authorized technical service of each country solves the problem (it seems that replacing a chip) or we Will have to be the users that we have to take charge of the management of this defect. (still under warranty)

Thank you very much and Best regards!
