Fender's Super-Sonic 100 tube amp head is designed for guitarists who want the inimitable sound of Fender clean tones plus expressive high-gain sounds in an all-tube, 100W amplifier.The Super-Sonic 100 head has a classic two-channel preamp with Vintage and Burn channels. The Vintage channel delivers tones based on legendary Fender favorites, with pre-gain tone controls and switchable voices for shimmering clean tones derived from vintage Fender Twin Reverb® and Showman® amps, and fat, punchy tone reminiscent of 1960s Bassman® amps. The Pre and Master Volume controls can be set for pure clean or slightly overdriven tones. The Burn channel ignites musical inspiration with overdrive flavors from bluesy to flame-throwing. Experiment with post-gain EQ and two-stage cascading preamp controls. Gain 1 provides edgy breakup and distortion while Gain 2 adds compression, thickness, and sustain. The Notch Tune feature lets you move the midrange notch for a variety of American and British flavors. The Super-Sonic 100 amp is capable of modern high-gain overdrive and sustain, but these characteristics can be fine tuned without masking the tonal character of your guitar. The Super-Sonic 100 head also contains impressive extras like the Arena/Club switch, which provides 25W output. The Damping control on the rear panel lets you select Normal, Loose, or Tight speaker response. And the all-new Fender Automatic Bias control (patent-pending) lets you easily set your output tubes to the recommended factory setting without a meter or tools. The bias can be set hotter or cooler if desired, and almost any mix of 6L6 power tubes will work.The Super-Sonic 100 head includes a cover and a 4-button, pedal board-friendly footswitch.
