Fender Super

A fixed-bias output stage and split-phase inverters helped the Super overdrive more quickly than the Fender Bassman and produce a sound that, according to Vintage Guitar's Dave Hunter, "in the estimation of many a vintage-amp fan, is among the sweetest and most delectable of any amp ever made."

Accordingly, the 5G4 Super Amp was clad in light brown tolex and outfitted with a forward facing control panel.

The Super, however, was the only one of these updated Professional amps to retain its tube rectifier, giving it a unique sound more akin to the preceding tweed 5F4 design.

The 6G4-A however typically sports standard brown tolex with wheat colored grill cloth and delivers approximately 40 watts of power.

These transformers had thicker gauge wires than the previous Triad version (stamped 45216) and handled the higher power with less stress.
