Hi
I a line 6 M5 and sound very low compare with the true bypass.
I live in china.
Refer to the link https://line6.com/support/topic/3844-my-m9-sound-very-low/
I try to contact the china service center,
but Unfortunately, they don't know hoe to fix this issue.
I have some hands-on repair circuit board ability ,Could you share me the detail repair method?
or send me the repair method to my email:27653276@qq.com
Thank you very much.
