Powerful, innovative and versatile for stage and studio alike, the Bassman 100T is a professional-level 100-watt tube head with enormous Fender bass sound and sparkling vintage Fender looks. Its dual-channel design uses modern technology to maximize classic technology, with classic Fender late-’60s/early-’70s “blackface” styling and a wealth of innovative features on the front and rear panels. Features include a tube preamp (two 12AX7s) and power amp (one 12AT7 and four 6L6s); 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; XLR output that delivers overdriven power amp tone (great for recording); rear-panel Output Power switch that lets you play or record at full 100-watt power, quieter 25-watt power, or silently via internal power soak (which captures the signal post-power amp); impedance switch (8, 4 or 2 ohms) and master volume with push/pull mute.
