This Gallien Krueger 400RB is in very good condition with light rackmounting wear and it is missing one mini switch.

This GK head is a 400 watt single channel rig with front-loaded direct out. Bass, treble, lo and hi mid, and presence controls let you dial in the 400RB III for any bass or cab, and there is an onboard contour shift, with a tone shift for 5 string basses. Besides IEC and two speaker outs, everything is on the front panel of the amp - DI out, effects loop, tuner out - making this head easy to patch in during a five minute load in.
