My line 6 lowdown hd400 makes a loud noise after I switched it off even with the master volume down. I assume it has something to do with the caps discharging. Die anyone know how to fix this? Cheers, Peter

I have a FBV Shortboard connected to my LD400 PRO amp. For a few months now it sometimes happens that when I step on the Bank Up or Down footswitch that the amp starts cycling through all presets and I can't stop it apart from switching it off and on again. I have already ruled out faulty foot switches and connection cables. Have you heard of this before and can you suggest further steps to troubleshoot? An unrelated problem is that plugging in headphones does NOT turn off the speakers. Any suggestions for that? Cheers, Peter
