Hello I have a trouble .. while I turn on "amplify 150" guitar nest randomly unplug (no sound from guitar) in interval between 1-10 minutes (this happening 1-2 times each turn), after unplug and plug, guitar work normal.. but this happening each time when I turn on my amplifi. if I plug guitar after 10 minutes its work fine.. sorry for my bad English...
