A powerful 280W solid state with the warm feel and sound of a tube head.
GK's RB Series bass amplifiers have been setting the standard for over two decades and the 280W 400RB-IV continues that tradition. Inside this compact, lightweight ˜superstructure' is the most advanced bass circuitry available. In 1972, Bob Gallien developed what he calls G.I.V.E. Technology (Gate Induced Valve Effect). This ˜valve effect' is integrated into the design of all RB Series heads and is part of what gives them their distinct sound. The 400RB-IV Series bass head delivers a warm, punchy tone with a fast transient response that not only sounds better, it feels better. GK's renowned voicing filters and intuitive four band active EQ make it simple to dial in a great sound. Every day thousands of players around the world in arenas, clubs and basements plug into GK heads because they love that sound.
