Compact, portable and lightweight single-channel amplifier for electric bass guitar that offers seismic Fender bass tone and stage-worthy features, producing 500 W of pure bass muscle and finesse. It also offers classic Fender styling and Fender’s magnetic Rumble head-attachment system that properly secures the amplifier in place during normal operation. The single channel is equipped with an Overdrive switch that provides gritty, aggressive, incredibly rich and satisfying overdriven tone; and a versatile three-button tone voicing, consisting of a high-end-boost ''bright'' switch, mid-scoop ''contour'' switch and old-school tube-emulating ''vintage'' switch.  For easy compatibility with external stage and studio performance and recording systems, the combo features a rear-panel XLR line output with ground lift switch. It also features a headphone output jack for convenient personal listening at any time. The lightweight chassis is made of aluminium and steel and features a painted metal front panel with red LED jewel.
