Hot or Not: Fender '57 Twin-Amp

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.

Way hot! I love the tweed look and the textures that amp puts out sounded great. Mark, now you know what to get me for Christmas :)

haha. no. I actually need an amp younger than myself for gigs before I start buying anyone else presents. :embarrassed:

very cool, very loud amps. i considered one when i bought my Allen.

I've never tried one but I really dig the tweed amps for the blues gigs I've been playing...I'll eventually probably do a Weber bandmaster kit like Prages and Modern Saint.

i liked the cleaner sound of the twin over the tweed bandmaster and bassman. just a thought.

My new landlord has an Allen Accomplice. They're really nice amps. I thought about getting an Allen before I settled on my Gretsch. Did you assemble it or get it finished?

Mark: I like that Tweed Twin a lot.

David built my Encore for me. it's a 2x10 with a 40 watt transformer and Ragin' Cajun speakers.
 
I wonder how they take pedals....

If the 57 circuitry is similar to the 59 than you are looking at a traditional Marshall type schematic. After all Jim Marshall used that schematic for the JTM45's if memory serves me well less tube types of 6L6 vs. EL34's.

As for the difference between a 57 vs. 59, I would need to check my schematics when I get home to really see the difference.
 
After looking through my schematic books, the 5E6-A circuit was the bassman circuit for the years 1956-1957. This is the Bassman circuit that contains the double 5U4 rectifier tubes. Preamp tubes are V1 and V2 - 12AY7, V3 - 12AX7 and 6L6G for the power tubes. Tone stack is treble and bass with prescence

The 1959-1960 bassman circuit is the 5F6-A

As someone mentioned earlier, the 5E8A is for a Fender Twin between '55 -'57. The Twin has V1-12AY7, V2-12AX7, V3-12AX7 and the power tubes are 4-5881's. Tone stack is TMB with Prescence. Rectifier tube is a single GZ34.
