The result of these factors was a rhythm guitar sound that seemed to float somewhere between the low-end thump of the electric bass and the cutting tone of the snare and hi-hats, with a rhythmically melodic feel that fell deep in the pocket. Guitarist Jimmy Nolen, longtime guitarist for James Brown, developed this technique. On Brown's "Give It Up or Turnit a Loose" (1969), however, Jimmy Nolen's guitar part has a bare bones tonal structure. The pattern of attack-points is the emphasis, not the pattern of pitches. The guitar is used the way that an African drum, or idiophone would be used. Nolen created a "clean, trebly tone" by using "hollow-body jazz guitars with single-coil P-90 pickups" plugged into a Fender Twin Reverb amp with the mid turned down low and the treble turned up high.
