Hey, I had bought an EHX MIG-50 from a store in Grand Rapids, MI, and it had a bunch of rattling screws within the enclosure, and soon stopped working completely. Then, I had it exchanged for another MIG-50, but it does what the earlier post on here said. There is a loud pop-like sound and it just dies. No sound comes through it. Being the second MIG-50 this has happened to, I’m very frustrated. Is there any way this can be permanently fixed, or should I just send it back for good?
