I'm too dumb to add a new page, but I'd like to start slowly adding my spot models to the wiki. Someone smarter than me added my SI850 not too long ago. Here is a 550 variant that hasn't been properly documented yet. RG550I-V. I'll take better pictures down the road and provide more examples of this model. These are dated to 1990. The pickups on mine are not stock, but the knobs, switch cap, and scalloped fretboard are. I have seen 4 picture examples of this model, more examples over text, and they all shared the same specs. 1990 serial, black pickguard, 18-24 frets scalloped, yellow inlays, coloured plastics. These were written off as "JEM modded" RG5000DYs on Jemsite over the years, but these have had consistent specs over each example, and the serials/inlays never matched the RG5000DY. As for what the "I-V" means in the name, I am unsure. I assume "I" is for Inlay, V could be anything
