Gallien-Krueger

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.

Features

  • 280 watts (4 ohms)

  • Adjustable contour, presence & 4/5 string voicing
  • Boost (Valve Effect)

  • XLR out with level, ground lift & pre/post switch
