Why these settings

The Fender Rumble 100 has a naturally warm, slightly scooped voicing with no presence or reverb controls. Rex Brown's tone relies on hard pick attack, high-mid punch, and subtle tube grit, so the amp's mid and treble are pushed while the Low-Mid (7) and High-Mid (8) knobs handle definition. Engaging the Bright switch and blending the TRBX304's active pickups compensates for the Rumble's dark upper register.

PRO TIPPlay aggressively with a heavy gauge pick (1.0mm+) right between the two pickups, digging hard into the strings for maximum percussive clack.
