Why these settings

The Rumble 40 has a naturally scooped, hi-fi voicing compared to Zild's warm, vintage 70s studio tone. Pushing the Low-Mid/High-Mid frequencies to 7 and cutting Treble to 4 brings out the necessary fingerstyle funk punch while taming modern top-end sizzle. Set Low-Mid to 7 and High-Mid to 6 on the Rumble 40 faceplate, and keep the Contour, Bright, and Vintage voicing buttons disengaged.

PRO TIPPluck directly over the neck pickup or the end of the fretboard with the flesh of your index and middle fingers, applying light palm-muting with your right-hand heel on staccato funk pulses.
