That's interesting. I have never had the squeal happen with my factory installed Graphtech Ghost System on my Private Stock 513. What happens with that one is that it cuts out when you dive bomb has the strings break contact with the saddles. Definitely, it's a involved factor with LR Baggs design. The LR Baggs system also requires that the pick ups be reverse wound which is why it was unsuitable for a three pick up guitar where the middle pick up is reverse wound and 180 degrees out of phase with respect to the the neck and bridge pick ups for hum cancellation.
