Fender Super Reverb

[1][2] The Super Reverb is commonly used by blues guitarists due to its ability to deliver loud, warm tube distortion through its four 10" speakers.

[3] It is also known as having a scooped mids tonality, meaning that there is less midrange and an emphasis of sparkly treble and full, round bass frequencies.

Tube (valve) complement: Two channels: Normal and Vibrato, with Bright Switch Dimensions: Some early Super Reverb amplifiers came with the option of factory equipped JBL speakers instead of the Jensen, Oxford or Utah speakers widely used in the majority of Fender amplifiers.

The JBL speakers had aluminum dust caps with larger magnets and voice coils, this gives a fuller response range and handles more power reducing the risk of "blowing a speaker".

These models also add to the overall weight of the amp, making casters (wheels) a very good option.
