Used Gallien Krueger 700RB Bass Amplifier Head

The Gallien-Krueger 700RB is a solid-state bass amp head with 480W + 50W bi-amp power output at 4 ohms, featuring an active 4-band EQ, Boost and Presence controls, and effects loop. Its key specs include a robust, reliable design with a toroidal transformer, balanced XLR out, and separate woofer/tweeter volume controls, making it a popular choice for professional and touring bassists.

This is a great deal, lots of amp for the money.

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.
