I have a limited ed. JP6 with a mahogany body and a roasted maple neck/pao ferro board.
The crunchlab was too sterile for me so I put a Holy Diver and VHII neck. Had them for a while and it was wonderful.
It now has an Abraxas bridge and the VHII neck and it's still awesome. I'm thinking about trying a Crawler I have too.
This is a similar spec to my guitar. If you get a chance could you tell me how you felt about both pickup sets? How would you describe the sounds as compared to the stock pickups? Would love to hear your thoughts. Played the JP this morning in church and the bridge pickup is definitely a little too cutting for me.
Well mine is a JP6 so my stock pickups were the CrunchLab bridge/LiquiFire neck combo so I can only talk about those.
Your JP15 has Illuminators in them which are supposed to be a bit less surgical sounding, but I never tried them.
So coming from the CL/LF combo, with the HD/VHII, it changed the very modern feel/sound into more of a modern vintage rock/hard rock Suhr superstrat sound, which is what I was aiming for.
It became far more versatile.
The HD/VHII is a very reliable combo that many people uses because it covers a lot of grounds.
OTOH, the HD is less prone to Modern Metal sounds such as djent/metalcore than a Crunchlab.
The Abraxas shifted the general feel and sound more to the vintage side of things while still retaining massive versatility.
As a rule of thumb, what I always experienced when replacing DiMarzios with BKP is the enhanced dynamics as you lost a lot of the compressed sound (which can be good or bad according to your needs).
Basically, the HD is a bit more powerful than the Abraxas (surprisingly not so much) and with a good general focus on the mids (it's very musical, best leads of the BKP range for sure) and the Abraxas is more of a very well balanced super PAF, it does so many things right.
I feel the Abraxas doesn't get enough recognitions as it's basically the Super PAF that all other brand would have hoped to make (looking at you DiMarzio...)
As for the VHII, I'm biased because it's my favorite neck pickup (with the Emerald neck).
It's like playing a big single coil, with plenty of fendery-attack but as the same time still sound like a fat humbucker for jazzy runs. It's really great.
Also, the trick with the JP6 for me was to choose pickups that were hot enough on one of the coils to retain the beautiful 'Petrucci' middle position (both inside coils splitted in parallel) and the VHII is one of the neck pickups that does it well in my experience.
The HD worked too, but I feel the Abraxas does it even better now (the Crawler is supposed to be the greatest splitter by the way).
Oh and be aware that if you want to retain the original JP wiring you got to order the neck pickup with the magnet flipped ! (and Tri-Tabs on both like the guys said !)
Good luck !
