That 1991 550XL reminds me my charvel fusion plus - because of scaloped low horn. Maybe it is some kind of fusion?I've been spoiled by my Jackson/Charvel's from the get-go. Nothing else feels like "home" to me. I've had a few Soloists and a DR but am down to my two faves that I'll never let go of: my 1989 Archtop Soloist and my 1991 550XL. I also have a Jackson strat that is my studio clean machine.
