I have posted on another thread that I have a guitar with Seymour Duncan Screamin 'Demon, that pickup never satisfies me. Weak output, too much mids, etc. I have a Seymour Duncan JB in my closet that never gets use. My guitar is a Brian Moore C90F, with mahogany body and a maple top. What you think about the JB? It combines well with a mahogany body? My neck pickup is a Seymour Duncan 59.
