The power amp included a "long tailed pair" phase inverter, an innovation that noticeably increased the "headroom" or clean power output capability of the amplifier.

Similar preamp changes were also incorporated in the 5F8 Twin Amp at about the same time, but not on other large size Fender amps.

The modern edition of one of the greatest guitar amps ever made.

The mighty 4x10" Bassman began life as a bass amp before guitar players discovered its sonic wonders and adopted it as their own.

This final 1950s Tweed Bassman model product line included a change from the 5Y3 to the GZ34 rectifier tube, as well as a modification within the Presence control circuit.

Besides being a popular and important amplifier in its own right, the Bassman also became the foundation on which Marshall and other companies built their high-gain tube amplifiers.

5B6 Bassman amplifiers had two 6SC7 or 6SL7GT pre-amp tubes, two 5881 power tubes and a single 5U4G rectifier tube.

Designed by Freddie Tavares, longtime R&D man at Fender, Instead of the single 15" speaker, four 10" Jensen Alnico P10R speakers were used.

The circuit had two innovations: a fixed bias for the power tubes, which increased power in comparison to the earlier cathode bias design, and a cathodyne phase inverter, using half of the 12AX7 tube and allowing a third gain stage on the other half.

The 5F6-A Bassman's design was directly copied by Marshall Amplifiers within their JTM-45 amplifier during the early 1960s. The first series of the reissue were made at the Corona, California facility, and came equipped with four Eminence-made 10" blue frame Al Ni Co speakers, and a solid state rectifier unit.
