Late to the party but this has been happening to me. It was just very occasionally to start with but has gradually increased. It did have a minor blip at a gig last week but seemed mostly fine until yesterday when it went full monty, stuttering and cutting out. I'm on 3.15 (current latest release), cables all good, passive pups etc. I have done a full reset and restored the back up and so far during one rehearsal it seemed okay. Curious if anyone else has had this problem and if this solution fixes it ?
