Also, does BKP make the triangular mounting tabs as on Dimarzio as the JPXi is routed for triangular fixing.
Yes. Just ask for TRI TABS in the comment box.
Also, i have a JP6 (mahogany body/maple neck/Pau Ferro board) and i'm thinking of swapping the Crunch Lab/Liquid Fire for a Holydiver bridge and Emerald neck, but i'm looking to take the guitar in a more organic/vintage territory.
The HD has quite a strong midrange push, as the CL, but is infinitely more dynamic and less compressed than the Crunchlab.
A good replacement for the LiquidFire would be the Coldsweat, that is if you want to keep the same general vibe, the coldsweat is a lot cleaner.
