Get Unparalleled Flexibility And Design With The Gallien-Krueger 2001RB 2 Way 500+50 W Bass Amp Head

BI-AMP FLEXIBILITY- Unique Horn Bi-Amp system sends the high frequencies to the horn through a separate 50W amplifier. This has many advantages: The horn level is controlled from the front panel. The horn is not overpowered by the larger amp so failures are reduced. When the woofer amp hits the rails (growl) the horn stays clean.

TONE SHAPING- 4 band active EQ and voicing filters based on the classic 800RB provide extensive tone shaping capability.

DRIVE- Drive channel with independent EQ and volume for moderate grit or full grind.

CONNECTIVITY- Balanced DI with level control, Pre/Post and Ground Lift switches to feed the house, Tuner output, FX Loop for connecting outboard accessories on the front. And two ¼ inch speaker jacks and two twist lock speaker connectors to ensure reliable and safe cabinet connections, mounted in the rear.

POWER TO SPARE- Two 540 watt power amps allow bridged or dual mono operation for expanded cabinet and speaker load options.

HARMONIC COMPLEXITY- Boost control adds tube like harmonics and signature "GK growl" using G.I.V.E. technology.

BIG IRON- Dual rail Analog power amp and toroidal transformer provide the current required to control the speakers at high volume.

VARIABLE Q- Inherited from the 800RB, this unique design varies the EQ bandwidth to retain a musical response even at extreme settings.
