Got the new G10TII, Sometimes it connect, sometimes not, it's not a question of a real technical problem. But depends of your guitar output plug, as I have quite a "few" guitars I regularly change it's annoying, I won't fit to all my guitar outputs for this tool, go back ro my independent transmitter and receiver wireless for my Yamaha THR10 II W and 30II W.
Very irritating, solve this and i'll be your man, so if it is like now I won't.
Especially old Tele outputs give problems and I'm not gonna change my real vintage stuff, but also others, new D'Angelico's etc.
So please look if you can find a solution
