Hello ! I'm using a MIKE POPE Flexcore 2.2sk and this crazy noise just appeared ! This is too crazy for me ! LOL ! When I'm plugging the bass, if I just put the half plug inside the jack starts a crazy noise like a diesel motor ! LOL ! But when I plug it 100% this noise just stop ! Do you know why ? It wasn't happening before ! In passive mode , it's ok ! Crazy ! Any thoughts ?
