Tweak voicing for 4- or 5-string bass with the String Bass button

The 400RB-IV lets you effortlessly switch between instruments at will. A 5-string bass requires entirely different low end amp response than a 4-string instrument. Equalizers cannot accommodate this fundamental voicing difference, but the 400RB-IV's String Bass button does just that.

G.I.V.E. technology for punchy tubularity

The Gallien-Krueger 400RB-IV bass head employs GK's G.I.V.E. (Gate Induced Valve Effect) technology, which lends just the right amount of tubularity and grit to your bass, while proprietary voicing filters and intuitive 4-band active EQ let you zero in on your signature sound quickly and easily. The 400RB-IV delivers classic GK tone in a compact, lightweight package.

All the tools you need to dial in your perfect bass sound are onboard the Gallien-Krueger 400RB-IV.
