I will showcase two Fender tweed amps- a Fender Custom 57 Twin and the Fender Eric Clapton Twinolux amps. The two amps are beauties and are different in a nice way and complement each other. I bought the Fender Custom 57 Twin in 2003 and the Eric Clapton Twinolux in 2013. FENDER CUSTOM 57 TWIN: The Fender '57 Twin was played by many icons of the 1960s. Manufactured by the Fender Custom Shop with a finger-jointed solid-pine cabinet, it has two channels, one bright and one normal and individual Volume controls. The Tweed Twin is an all hand wired point-to-point amp on eyelet boards with high quality components and Mercury Magnetics transformers with a nice tweed covering. This 40-watt Twin is powered by 6l6GE power tubes and rectified by two 5U4s bringing back the late 50s Fender dual rectifier design. Four 12AX7 preamp tubes, 3 of which may be substituted with 12AY7s for the original '50s low-gain sound. The transformers and choke are from Mercury Magnetics Company. There's also an internal bias pot that allows easy substitution of various 6L6 tube types. Control panel include Normal and Bright volumes, 4 Inputs (2 Normal, 2 Bright) which can be jumped and results in a different sound and distortion. Plugging in and you at once feel the harmonically rich and clean tones. A great amp for authentic rock, blues, and country playing. When cranked up, the Twin-Amp's fat distortion tone sounds great. It's a loud amp. The dynamic response and purity of tone of the 5E8A circuit are recreated in this Tweed Twin. AS you play through the amp, you will note the the Fender '57 Twin combo's finger-joined solid pine cabinet resonates with a warm, woody tone. Crank it up for fat and sweet distortion. It ahs a nice touch sensitivity. I think, the 57 Twin's 5E8a sounds best with the guitar plugged straight in as you can control the amount of gain and distortion with the volume on the guitar. Crank it up to 7 and you get a nice breakup. The sweet spots are easily found using the amp’s Bass, Treble and Presence knobs. Definitely a great amp to own, play and collect. FENDER ERIC CLAPTON TWINOLUX: This is the only Fender amp in the line that's a signature amp, specifically made for Eric Clapton. The Fender EC Twinolux is the result of a collaboration between Fender and Eric Clapton. Eric Clapton wanted a modified version of the classic tweed '57 Twin amp, so Fender produced a hand wired combo voiced to Eric's preference. The EC Twinolux is based on the ’57 Twin—a reissue of the 40-watt tweed Twin described above. Hand wired and all-tube circuitry in a single-channel design, you have Volume, Treble, Bass, Presence and dual Weber-designed Eminence-built 12" speakers. Four 12AX7 preamp tubes and two 6L6GE tubes in the power amp section. Includes the '50s era tremolo design which is a bias tremolo, which has a more distinct throbbing pulse than later Fender designs, sounds terrific. The finger-joined solid pine construction makes the amp sound warm, defined, and punchy. And the built-in switchable power attenuator resulting in 40W (full power) or 10W with both speakers on, or 10W with one speaker on, makes it ideal for bedroom, studios, smaller venues and larger venues as well. The circuit is based on the 5E8-A schematic that’s the foundation of the narrow-panel original. Like the original Twin, the Twinolux has dual 5U4GB rectifier tubes. The cabinet comes with two 40-watt Weber-designed alnico speakers (built by Eminence), and transformers built by Mercury Magnetics. This amp has warmth, depth, and character. The tone is amazing as you can get a warm tube distortion at low volumes to a great sound at stage volumes. It's not modern sounding but very much older-style sound. The gain on this amp is amazing. Crank the treble, bass, and volume, and you have a huge sweet distorted sounds. These amps are a nice complement to each other in that they provide a wide suite of tones, with focus on the 60s style rock n roll and blues. If you love that sound and the blues, these amps have the goods. They have been well built and designed. Thank you Fender!
