I think your post is still too vague
"from blues to mastodon" doesn't say much
most BKP humbuckers were primarily made for les pauls
I love the cold sweats in my '73 lp custom
neck pup is extremely balanced and warm, but still tight and clear enough for rhythms
bridge pup is bright and crunchy, without any bass or mid bump, in a way that it really matches a good thick sounding les paul custom
it had nailbombs before and they sounded huge too
neck pup was a bit too hot and scooped, but very clear with a strong picking response
bridge pup was fat and focused, not scooped, but far from middy
like a metal PAF with a lot of sustain and huge output
I also love the holy diver and miracle man in les pauls
holy diver is very fat and powerful, lot of center mids,fluid leads, warm top
miracle man has a strong bass response, not much mids, sharp top, really clear lead tones and kinda reacts like a JCM... the louder you play it, the bigger it gets
for a stock JCM 800, I wouldn't go with a PAF model if you want to get real gain and sustain from the amp
