Does the guitar work with the mag pickups, when modeling is turned off?
If you are using the battery for power, is your battery fully charged? If you are using the VDI - HD500 connection, are you sure your cable is good?
Thanks for the quick reply.
The mag pickups are working sometimes and sometimes not. Did not get why this happens (I restarted pc few times and after connecting again I experienced the problem with the magnet). The battery is fully charged or almost full. Cable is good since it works with a Variax 300.
As I said in the shop (connected to an amp) the guitar worked fine. I wonder if it has to do with the firmware upgrade.
