This unit effectively reproduces the 1955-1957 edition's low-powered 5E8A circuit, which produces 40W into a pair of 12" Alnico-magnet speakers. Its harmonically rich, clean tones are great for authentic rock, blues, and country playing; when cranked up, the Twin-Amp's fat, sophisticated distortion tone works wonderfully in many modern musical situations.The '57 Twin-Amp gets its power from a pair of USA-made GT6L6-GE output tubes. The power supply includes Fender's rarely seen '50s dual rectifier arrangement, which uses two - 5U4 rectifier tubes. With this design, power amp compression, or sag, is more subtle than it is in many Fender Tweed designs. The preamp contains four high-gain 12AX7 tubes, three of which may be substituted with 12AY7s for the original '50s low-gain sound, if desired. There's also an internal bias pot that allows easy substitution of various 6L6 tube types.Control panel details include: Normal and Bright volumes, 4 Inputs (2 Normal, 2 Bright), Treble, Bass, and Presence knobs.The '57 Twin's finger-joined solid pine cabinet resonates with a warm, woody tone. The amp is covered in genuine lacquered tweed, and a vintage brown/gold grille cloth and leather strap handle complete a very vintage package. Fitted cover is included.
