@Bman tell me if this isn't the coolest thing you've ever seen? Viv playing all the classic solos at a Last in Line sound check. I was out front taking it all in. He was not playing his fractal from the DL rig but rather a VERY Loud signature Blackmoore Engl 1/2 stack.

For the last 10-12 years or so I've been putting ceramic magnets in the JB's in all of my guitars. Really tightens up the bass and has clearer mids for drop C which I always play in. From what I understand, the JB and Duncan Distortion are either identical or near-identical with the exception of magnet choice. JB uses an Alnico 5. Distortion uses a double-thick ceramic. Too harsh, IMO. A JB with a regular Ceramic 8 is a great middle ground. It's been a key part of my sound forever.
Anyone who has a JB and is less than thrilled with it...ceramic mags are a cheap mod.
Would the Duncan Distortion be close to the same thing? It's got a ceramic, I believe. I have one in another guitar and it sounds great. I bought it in 1987 because I read George Lynch used them. It replaced whatever bridge pickup came in the RG550's of that time period. I thought I read somewhere he's either going back to using them or maybe issued a 'Dokkenbucker' that's close to it.
