Fender Harvard

The Harvard appeared only in a tweed covered "narrow-panel" cabinet, but in two very different circuit designs, namely 5F10 (1955–61) and 6G10 (1962–63).

The amplifier had a very simple circuit and used only a single channel with a two-stage preamp, with just a volume and (treble-cut) tone control.

The extremely rare 1962–63 6G10 Harvard[5] used a single 12AX7, 6V6GT and 5Y3GT;[4] it was simply a way to use up leftover 50's Princeton (5F2-A) chassis and tweed cabinets, after Fender had re-launched an all-new class AB Princeton (6G2) in a Tolex-covered "brownface" version.

The Harvard filled a gap between the student Champ and Princeton models and the professional Deluxe.

[7] Stephen Stills is also a user of the Harvard particularly for overdubbed solos, the quick compression when used with humbuckers leads to a fluid lyrical single note passages.
