It's about 8 yrs old, never an issue until I turned it on today. Heard a loud pop, and now I only get a loud squeal. The lights all work but no guitar sound comes out, just the squeal. Did a reset, no luck, also smelled a weird electronic burnt smell. I am thinking this thing is toast. Can be the only person in this situation, any info on this or idea on cost to repair it.
Thanks
