So I just had my JTV Korean do this to me 2 weks ago and it is just dead. lights came on played a bit and it just faded. I had the switching issues in the beginning. I will try this but things are not looking good. I have triede all flashes and rolled back to 1.9 as I had doubts about 2.0. I hope this little tweak works as I have not had good luck with these. For three main parts these should be better. !switching dead right out of the gate-now fixed, now switching models/tunings is dead and Line 6 says it is all on me...only thing left is a battery that works so far but is worthless to me. If the battery dies you can't even order one so guess it may be the beginning of the end. This guitar is a headache. Trying this now.
