From Fender:

High-performance, no-nonsense tube amps that create unmistakable Fender clean tones and expressive modern high-gain tones without masking the tonal character of the player's guitar. The 100-watt Super-Sonic 100 Head contains several sonically versatile features, including an Arena/Club switch that takes the power down to 25 watts; a Notch Tune control that lets you move the midrange notch and fine-tune the distortion characteristics for a variety of American and British amp sounds; a rear-panel damping control that lets you select "normal," "loose" or "tight" speaker response for sounds ranging from warm and loose to tight and focused; and Fender Automatic Bias control.

4-Button Footswitch

This head is in Excellent-To-Near-Mint condition, showing signs of very little use and careful storage. There are extremely minor scuffs on the tolex that are difficult to capture in photographs. The Footswitch has a small area off adhesive residue on the face. This package includes the original 4-button footswitch and cable, original Fender slipcover, original manual, original bill-of-sale, and a power cable. This unit is set for Local Pickup Only, due to its weight and fragility.
