Recently I bought a second hand/used LINE 6 Spider Valve 112
After an approximate an hour of operation my amplifier starts to fail when you change channels, turning off the sound and channel light for 2 sec and continuously reset the channel. The whole metal chassis gets very hot, even the on / off and standby switches reach a very high temperature. I use a FBV express pedal , but the amp do the same malfunctition even without using it.
Sometimes the stored banks channel information has been deleted, as if it had done a factory reset
help !
