Question about IBZ pickups circa 1989
I have a 1989 RG560 I bought new back in the day. I was wondering if anyone knows anything about the pickups on this guitar. The two singles are labeled IBZ S1 and the 'bucker (in bridge position) is labeled IBZ V2. Were these IBZ pickups co-designed by Seymour Duncan? What's the general opinion on their quality? I haven't played many different guitars, so I don't have a lot to compare them to.
Also, in regard to an earlier thread on model features, my 560 has a black headstock. It is not color-matched to the body, which is a sort of purple-ish burgundy, depending on the light.
