I have a bunch of Gibson pickups under my 122 or so strings currently in service. I bought a pair of 57 Classics for my LPJ. They were OK, but I missed the 490/498 stock pickups grit. They ended up here: My 03 G-400 Vintage. I have to say that the 57s are clear, adapt to pedals and overdriven amps well, but straight into a clean amp, they are bland. I find the OEM "Hot 57 " Epi pickups more suited to metal and hard rock, though less defined when the volume and tone are rolled down. I have to say that I find the 490s and the DirtyFingers are both capable of matching the 57s cleans and exceeding their tonal range. Perhaps it is my long relationship with P-90s that also makes the 57s seem "thin" sounding. Maybe it's just me.
