Well, I'm currently using my Ibanez SR500 (With double MK1 pickups) and it has a very warm sound, and I messed around with the bass and amp settings a bit to get closer to Claypool's 4 string Walnut sound. I go to the point that every note sound the same as his UNLESS I strum it. Claypool's strum seems very solid, while mine seemed hollow... Is there a kind of string that would allow me to get closer to that Claypool sound? Would flatwounds work better than roundwounds? Or steel better than nickel? Please help, thanks!
