guitbasse

i did a test today using a short 1/4 cable from my roland gk3 midi pluged in the guitar a full battery in my jtv I tested the other side of the 1/4 cable with a multimeter but there is no signal at a all i sounds like there is no contact inside the jtv i changed the volume knob to diff positions :huh:

note in all situation i can hear the default sound of my guitar

maybe the 1/4 cable is no more turning on the guitar or the variax

the 1/4" cable should be pluged in the amp?

if i find one hd500x, can i flash it ?

i did but and i can hear only the default guitar sound on my amp the usb interface still red on the variax in side and no blue led on the guitar tired to reset then guit as said in the manual but nothing happen ( no red light)

no the batt is full and still full until now
