hi if there is anyone with the knowladge or experiance on processor repair i need some help. I've been using Pod xt Live on stage and it started lightly at first but now it uncontrollablely switches tones between channels in the middle of a song while edit button is closed. For more clear explanation for example, when i play the rhythm section with clean channel that has gain on 1 and then switch to the distortion channel for solo with gain on 8-9 or whatever doesnt really matter, the gain of the distortion channel suddenly drops down to 1 same level as the clean channel i used right before. Is there anyway i can fix it myself at home there arent really any good lithuers around me and literally not a single one that can repair pedals etc.
