Ive been working on the bassline for Metallica's Orion, and when I try to move quickly to play the notes, the fretwork translates into clanking, even though I'm working damn hard to press the string as lightly as possible while maintaining quickness. At the same time, I've been trying to emulate "slap" http://www.youtube.com/watch?v=7sBis8v7CgU
and the main note is there, but there's an obnoxious high pitch tone sound. Both of these are minimized if I twist the mid scoop knob to the so called "slap/pick" function rather than "finger", as well as lower the treble boost on the bass to zero and lower the volume from max to about 6-7. Is there anything else I can do to alleviate the sounding problems? It's starting to get a bit irritating. I dont believe I had this problem with my old set of strings (they were, however, worn in for about 4 months). I bought a set of elixir roundwound, the old set was ernie ball, if that makes a difference.
