 Fender introduced a reissue '65 Super Reverb in 2001 featuring a printed circuit board design rather than the hand-wired circuitry of the original '65 Super Reverb.The Super Reverb is commonly used by blues guitarists due to its ability to deliver loud, warm tube distortion through its four 10" speakers.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.
