The Gallien-Krueger 700RB-II is a 480-watt (4 Ohms) + 50-watt (8 Ohms) bi-amplified solid-state bass amp head known for its punchy "GK growl" and high-current power. It features G.I.V.E. (Gate Induced Valve Effect) technology for tube-like grit, 4-band active EQ, specialized voicing filters (Contour, Presence, 4-/5-string), and a dedicated horn bi-amp system for clear, articulate sound.

The only thing that prevents this item from being in top "excellent" condition is a few cosmetic scratches.
