Also known as the "Woodie." Some of these models had two strips instead of the more common three on the front. This model was sometimes called the Model 26. This name appears on the control panel of the Deluxe and Professional amps. Later models have a 6V6 power tube instead of the 6F6.

Some of these models have a deep back panel. In 1949, the vertical tweed and dark brown grille was replaced with diagonal tweed and brown linen cloth. This model was 5A3.

Model numbers 5B3 and 5C3 are virtually identical, which were introduced with the wide panel tweed. The 5C3 featured a separate on/off switch, spare speaker jack, and a negative feedback loop. In 1954 the 5D3 Models was intrdouced and used minature 12AX7 and 12AY7 preamp tubes, and the negative feedback loop was removed. This was the end of metal tubes that were replaced by glass tubes.

The 5E3 Model was introduced when it switched to Narrow Panel. This model had a new ground switch and four inputs. When the model was changed to 5F3 from 5E3 the half of the 12AX7 tube was being used, leaving the other half as another preamp stage. This means the other half could be used to create higher gain. Musicians know the Deluxe as a model to distort at low volumes.

Tremolo operates on both channels. In 1961, Model 6G3 was introduced and had the channels reversed.

When the Blackface was introduced (Model AA763), it had separate bass and treble controls. Models AA763 and AB763 are almost identical. In 1966, some amps get the underlined Fender nameplates on the grilles.
Tremolo operates on bright channel only.

This amp was introduced at the same time as the Blackface Deluxe but lasted longer. The model name was the same as the Deluxe (AA763). In 1966, the Fender nameplate was put on the front.

A 1200 pF capacitor was placed on the grids of each of the power tubes, which cures instability that was on earlier blackface models.
