Fender Super Bassman PRO 300W Amplifier Head


The Bassman remains one of the most powerful and versatile bass amps Fender have ever created. This stadium-ready 300-watt amp head is designed for the big time, with enormous Fender bass sound and classic Fender “Blackface” looks. Its dual-channel design uses modern technology to maximize classic technology, with a wealth of innovative features on the front and rear panels.

Features include a tube preamp (2x 12AX7s) and power amp (1x 12AX7, 1x 12AT7, 6x 6550s); Vintage channel that delivers the full, warm sound of a classic Fender passive tone stack; Overdrive channel that delivers the aggressive and responsive sound of a modern active tone stack (choose between channels with included footswitch); rear-panel Fender Automatic Bias system that constantly monitors and re-biases tubes for perfect performance and alerts you when service is required; Speaker Output switch that can be set to “Mute” to turn speaker off and record silently using preamp tone from the XLR output; Impedance switch (8, 4 or 2 ohms) and master volume control with push/pull mute.
