I've recently purchased an esp f-254fm that I'm converting to a fretless, that I love the shape of, but cant stand the tone. It just sounds so tin-ney! So what Im looking for is passive pickups (I'm going to rip out the active circuit) to replace the current emg-hz's. I've got a few considerations in mind but thought I might ask for a few suggestions on how I might achieve a tone . Something in the vein of a cross between the bass tone on "would" by "alice in chains". Steve Digiorgios bass on any of the album "Individual thought paterns" by Death and A rickenbaker 4001. Quite a dirty grity sounding tone, but very concise at the same time. Not muddy.more a vintage tone than a modern sound.I know its something of a voodoo science with the reasults but I look forwards to hearing your replys.
