found the "Rig chances sound when you switch forwards and back again". system reset (hold system + turn on) does not help me.
edit.... played now for halv an hour... just don´t know if im hearing ghosts or not.... argh...
edit 2... i hear it... it´s like that sometimes the rig gets a blanket over it, and if you switch forward and back it back to normal clarity. all rigs do it... (info - i have -3.5db bass on the main output EQ - maybe that can be relevant)
