I have a partscaster franky type of guitar I keep trying pickups in. Currently have the 78 and I like it a lot but would like a little more output and slightly tighter bottom with similar high end clarity. The Perpetual Burn and Parallel Axis are next to try possibly. Can anyone compare? I have tried JB which I normally like but its too muddy in this guitar, Screamin Demon was almost awesome but too scooped for me, love the Pearly Gates tone but not enough output, Custom was just ok and so far the 78 is my favorite but I still want to try a few different ones
