Hey man, honestly not a huge fan at all of the miracle man 7 in the bridge of the jpxi. To me, the jpxi has a TON of low mids etc, and the miracle man just did not mesh with it in my opinion. Not enough attack or sharpness, huge bass and low mids, too much in my opinion. Weither or not you should switch them out, is up to you honestly. I like alot of the BKP stuff, and will probably continue to try different pups in the bridge of mine. the miracle man in the neck is SWEET however, love the fluid liquidy leads, sounds fantastic man.
