Mark V pb with clean tone ?

[sherbuel]

Hi
i have a mark V combo, and since a few week, clean channel seems to have a pb :when i'm in the tweed mode, everything is ok , but in the 2 other modes , sound comes sometimes after 1 or 2 seconds when i call it from my midi pedalboard, or sometimes no sound at all ! i have to touche the switch on the combo pannel and the the sound come back.it happens randomly.i changed tubes (just 1 2 3 and 4 , didn't have enough tube at home, have to buy new one) , same pb.
but in tweed mode, no pb everything is ok

did it happened to someone ? thanks for your help !

Sounds like a switching problem. Make sure all of the connections between the amp and the pedal board are solid.

hi and thanks for your answer.

everithing is ok , it works great with other channels of the amp (zero pb) and with tweed mode.
as soon as i put the clean channel in the 2 other modes : it may works 3 or 4 times and randomly -when i call the sound by switching it - the sound comes after one second or zero sound at all ..
i have to touch the switch on the amp then it works , and then it doesn't stop at all , no more pb.

if i call another channel then re call the clean channel , the pb comes back :roll:
