I bought the guitar from a young man for $100.00. He knew it had problems and told me so, but didn't know what was wrong. I can't fault him at all, he was up front with me. I took a chance. I'm hopeful the firmware can be reflashed & it will be OK. I've worked on guitars for years, and this one plays well now that the neck has been adusted & the action and intonation is set. I could easily keep it by the couch & use it as a practice guitar while watching TV, so I don't consider it a loss, just a learning experience. I put it in the closet for the moment, because if it's in front of me I'll keep messing with it, and not knowing how it works, I may do more damage than good. When the guy local to me has some time, we'll get it plugged in and see what happens.
