Hi, I'm new here and I have a problem so thanks to everyone who can help.
I use a Spider Jam with a FBV Express MkII pedalboard (bank select mode) but while playing a noise (some sort of huuuuuum) grow in the amp and I need to shut it down to make it disappear. I tried to disconnect the FBV, the guitar, both of them in any order, change program, start the playback, ecc... but despite of all this once started the noise remains. When I restart it (windows style) the noise is gone but after a while (say 5 to 10 minute) it starts growing again. The amp works fine without the FBV and both are brand new and updated with last firmware.
What else can I try???
