Why these settings

The Rumble 40's 4-band EQ maps cleanly here: set Low-Mid to 6 for that Ampeg body and High-Mid to 5 for pick attack clarity. The Yamaha TRBX304 active EQ switch should be set to 'Flat' or 'Pick' mode with the active onboard Bass and Treble centered. Leave the Rumble's Contour and Vintage voicing buttons disengaged so you do not scoop the mid frequencies needed to anchor the acoustic guitars and strings.

PRO TIPRobby Takac plays aggressively with a heavy pick near the middle position, resting the palm slightly for controlled, even dynamic decay beneath the orchestral swell.
