G's Bob Goffstein walks us through his latest review on the Fender Custom '57 Twin-Amp. This reissue is based on the '57 manufactured by Fender's Custom Shop, but features a few changes thrown in versatility's sake. The transformers and choke were built by Mercury Magnetics Company. The '57 includes four Sovtek 12AX7WCs, relabeled Groove Tubes 12AX7R, two Groove Tubes-6L6GE and two Electro Harmonix 5U4GB rectifiers. The speakers are 12" Eminence Alnicos designed by Ted Weber of Weber VST. In addition, this '57 reissue comes with separate Bright and Normal channels, each with its own preamp circuit, separate Volume controls and two jacks, followed by Treble, Bass and Presence controls that are common to both channels.
