Product details

Although this 400+ has a few nicks, it's actually the best example we've ever seen at both The Bass Shop and our former store, Bass Northwest. Includes A/B and EQ footswitches, manual, color catalog, and original hang tag.

Traditional style rotary tone controls, which shape the Bass 400’s all-tube character are fed from dual Inputs, one for modern active basses and the other for classic passive instruments. Each of these has its own separate tube input stage and volume control. A seven-band Graphic Equalizer further details the amp’s inherent musicality, making subtle or radical tonal changes possible and footswitchable.

No less than twelve fan-cooled 6L6 output tubes deliver 500 watts of transient power peaks with cool reliability. And this is no dirty dozen: this is a four-rack, twelve-pack of pure mean punch. You’ll be happy to know that tube life is commonly reported to range from three to five years, and often longer.

Other features include a 600 ohm XLR Balanced Out, Slave Out, blendable FX Loop with dual patch points front and rear, and a three-way switch for fan speed.

This thoroughbred stud has been a mainstay in the Boogie® Stable for over two decades and remains a classic in its own time.
