From Our Research Team:
Lightweight GK PowerThe rugged and lightweight Gallien-Krueger 400RB-IV bass head serves up 280 watts into 4 ohms. Shape your tone with the onboard contour and presence controls, tweak your sound to perfection with the 4-band active EQ, and dial in the perfect amount of growl with the Boost knob. Voice the amp for either 4- or 5-string basses with String Bass. With its high current capacity, the 400RB-IV doesn't need current limiting circuits, which rob your sound of natural transients, leaving you with unresponsive mushiness. With the Gallien-Krueger 400RB-IV, you get unadulterated GK power.
Gallien-Krueger 400RB-IV Bass Amp Head at a Glance:
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 four 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.
Shape your sound with 4-band active EQ, Contour, Presence, and Boost
The Gallien-Krueger 400RB-IV gives you complete control over your sound. Sculpt your tone with the 4-band active EQ, Contour, and Presence controls, then add just the right amount of growl with GK's Boost control. All the tools you need to dial in your perfect bass sound are onboard the Gallien-Krueger 400RB-IV.

GK 400RB-IV, my trusty ol' friend
by Nick B. from Hutto, TXIíve owned the 400RB-IV for six years now. Originally bought it in college because I needed a cheap and professional sounding amp, and thatís exactly what it is. The 400RB has a unique but versatile... read more [+] voice and I was able to pinpoint MY sound pretty easily. With a pick, I can dig into it and get a real punchy, aggressive punk sound. With fingers playing closer to neck, I get deep reggae or Motown sound Ė all without changing settings.

Music Background: former semi-pro, current hobbyist
At a time when I was touring regularly, my vintage SVT crapped out and I had to go a few weeks with my 400RB backup. Had no problem driving my 8x10, even at outdoor festivals with 2,000+ crowds. Consensus was the GK sounded better, so we didnít even get the SVT fixed, just went and bought a 1001RB as full-time replacement.
Most important, this thing is durable. I am known for being quite abusive with my gear and this thing has been dropped, rolled down the street, left in the rain and still kicks huge sound today. DI did go out after 5 years, but that was probably more my fault than a quality issue. close [-]
