RB SERIES FRONT PANEL FEATURES - cont.
VALVE-DYNAMIC BOTTOM/DENSITY CONTROLS
This is the very unique section of the RB Series bass amplifiers. Each RB Series amp includes an active
Bottom and Density control which EQ’s the power section for more low end tube warmth and high end
shine. The tube driven MOSFET power section, includes a 12AT7 tube plus a built-in EQ for authentic all-
tube tone and feel unlike any other tube, solid-state or hybrid power section. Adjust the Bottom control for
additional tube warmth and punch, then adjust the Definition control for more top end tonal attack. Use this
EQ in conjunction with the Preamp tone controls for unlimited tone shaping options.
PHONES JACK:
The filtered 1/4” Phones jack allow you to play or practice silently using a good quality pair of headphones.
POWER SWITCH:
This is the main power switch for the amplifier. Once the unit is plugged into an AC wall outlet or preferred
power strip conditioner, use this toggle switch to turn the unit ON & OFF. It will take 4-5 seconds,
like other all tube power amps, for the 12AT7 tube in the power amp to warm up and fully come on.
