The WT400 Traveler is our best Bass Guitar amplifier ever. It is a mainstay with touring professionals and back line companies. It produces an impressive 400 Watts RMS @ 4 Ohms with a minimum of 3dB of headroom. The sound is expanded with such features as 5 band semi parametric equalization, Automatic compression, Enhance control, headphone and tuner outputs, as well as a pro D.I. and full effect loop, input pad, and stereo Aux. inputs. You can take it anywhere in the accessory shoulder bag. As with all World Tour amplifiers it comes with all of the international voltage selection available internally.
