Gallien-Krueger 1001RB Fusion

Gallien-Krueger 1001RB Fusion – a 750-watt bass Bi-Amp amplifier head with a main amplifier section rated at 700 W at 4 Ω, a 50-watt Horn tweeter, a 4-band active equalizer, with a 1/4" input and outputs: 2 x 1/4", 2 x SpeakON, 2 x 1/4" for the effects loop, 1 x XLR for DI, and 1 x 1/4" for a tuner.

1001RB Fusion from Gallien-Krueger is an amplifier head with a Bi-Amp system designed for bass cabinets. An ideal choice for both stage and studio work, the unit combines a digital power amplifier with an integrated analog circuit, ensuring clean signal transmission and high dynamics even under extreme conditions. A separate tweeter section rated at 50 W guarantees precise high-frequency control while remaining independent of the main section’s overload, and the 4-band active equalizer with variable Q and voicing filters allows for precise tone shaping. Additional features such as a balanced DI output with level control and a pre/post switch, an effects loop, and a tuner output expand the sonic capabilities and integration options with external devices. The amplifier’s design, based on double-sided printed circuit boards and protected against short circuits, overheating, and RF interference, ensures stable performance even under intensive use.
