Ask and you shall receive! I'll probably do a full video covering the A and B section of JP's Glasgow Kiss at some point but here's something for you guys to chew on for now. They are in numerical order. JP6- JPXI- JPXII 7

As far as which one I would prefer I would say that each have their advantages. I love the rich warmth from the JPXI and JPXII but think the snappy sound of the JP6 just might make it a bit more versatile across a wider musical range. In band practice it does the split coil thing the most convincingly. It sounds pretty good over classic rock stuff like Jame's Gang etc. I would play my Al or ASS for that stuff live but when I take one guitar to cover everything from country to 80's rock stuff the original JP6 does it a bit better than the BFR models. The JPXI and JPXII nail the current Dream Theater tone, as if that would come as any surprise, so it's more enjoyable for me to play that stuff with those two. The XI and XII because they sound darker/warmer overall are especially good at the progressive rock thing, better than the JP6, but feel limited to that application for me personally.
I prefer the 15" radius for overall playing. I have smaller hands and it's almost impossible to do the hendrix type stuff on the JPXI's 20" neck profile. The more narrow 15" makes it just within comfortable reach to do the thumb over the neck style stuff ala Hendrix, SRV, John Mayer, etc. That being said, the 20" is just incredible for very technical material and can't be beat.
My JPXI is considerably heavier than my JP6. Of course, this will vary from guitar to guitar. The feel of the smaller bodied JP6 is more comfortable but I prefer the look of the JPXI and JPXII. I'm not crazy about the body shape of the standard BFR in terms of aesthetics.
I'd say if you're into a multitude of styles then you could be happy saving some money and getting the JP6. If metal and technical material is your thing then I'd say the BFR would probably be a little more up your alley. Take all this with a grain of salt. It's one man's opinion. Like I said before, if you can play them both then that's what you should do. Surprisingly, the JP6 was the most recent acquisition and it took me several days to appreciate it. I was not very impressed with it at first. I was not expecting such a drastic difference from the JPXI and JPXII. The more I dialed in the setup and broke it in the better it seemed to get. Now I truly feel they're all necessary parts of the collection and I wouldn't want to not have any one of them. If I just had to have one guitar though it would probably be the JP6.
