The Gallien-Krueger 700RB-II bass amp head serves up fast transient response and gobs of warm, punchy tone, giving your bass both roundness and articulation. This is one powerful beast - but you're in the driver's seat with built-in bi-amplification: a dedicated 480-watt power amp drives the lows, while a 50-watt amp takes deals with the highs. This arrangement is ideal for driving a wide range of bass rigs - including GK cabs equipped with their Horn Bi-Amp System. Whatever speakers you're driving, separate volume pots give you control over the woofer/tweeter mix.
