I don't know what else to do. I've been trying to understand what happened with my JTV-69 guitar, when I bought it, I used to use just a 1/4 cable and it was just plug and play but now the guitar just gets mute when I activate the push botton, when I deactivate it the regular mics works fine, all of them are ok but I try to use the simulations of other guitars using the 1/4 cable, the guitar just get mute, I think is something ablout firmware because the 1/4 port is working right. Everything is update it, I have done everything I know so far, I rollbacked, I roll fowarded. I think it has to exist a way to reset this system like unplugging the cable and then push the botton or something. Somebody knows how to solve this?
I already wrote to support team but they don't really helped me that much.
