Dr Know states that he "had a B.C. Rich Eagle that got stolen" in an interview with Premiere Guitar.

"My first guitar was a Bradley Les Paul copy, but Les Pauls were uncomfortable. I’d get a belly rash and arm rash—because we were digging in, y’know? In the CBGB’s DVD (Bad Brains: Live at CBGB 1982), most of that was an Ovation (UKII 1291) that Ric Ocasek gave me during the (Rock for Light) record." - Gary Miller.

In this video at CBGBs, you can see that Dr. Know Is using a PRS Stripped 58. Pretty sick guitar if you ask me.

When talking talking to Premier Guitar about the switch from Marshall's and Fender's, Doc says, " We were on tour with Living Colour, and Vernon [Reid]’s tech was a rep at Mesa. Vernon was using the Dual Rectifiers, but they didn’t have enough headroom for me. So I A/B/C’d the Marshall with the Dual and Triple Rectifiers, and the Triples had good headroom and could hold the bottom but also clean up like a Twin—because I need to have a very versatile amp. I use the 6L6 version, because it’s cleaner."

In this interview he said that he uses it.
