Fender amplifierFenderFender amplifiers are electric instrument amplifiers produced by the Fender Musical Instruments Corporation. The first guitar amplifiers attributed to Leo Fender were manufactured by the K&F Manufacturing Corporation (K&F) in 1945. Later, Fender began building its own line of electric guitars. Fender amplifiers would become favorites of guitarists like Jimi Hendrix, Eric Clapton, and Stevie Ray Vaughan, also known in these cases for playing Fender guitars. Fender amps have come in many configurations and styles. The early K&F and Fender amplifiers relied upon vacuum tube circuitry, with solid-state models appearing in the late 1960s. Fender frequently updated the internal circuitry of its amps, and changed their appearance throughout its history.

Marshall MajorMarshallThe Marshall Major is a 200-watt guitar amplifier built from 1967 to 1974. It was designed to produce more volume and clean headroom than Marshall's other amplifiers like the Super Lead. The 200 had only three controls on the front panel and used a preamplifier circuit that was closer in design to a hi-fi amplifier rather than a guitar amp. In 1968, Marshall updated the 200 with a typical EQ compliment of treble, middle, bass, and presence controls, and it was now named the Major. This tone stack—which was passive compared to the 200's active controls—was placed between the second and third gain stages created using ECC83 (12AX7) preamp tubes. Ritchie Blackmore of Deep Purple and Mick Ronson of David Bowie's band are frequently associated with the Major.

Orange OR120OrangeThe Orange OR120 is a 120-watt tube guitar amp head built around four EL34 tubes. It has high and low inputs, echo send/return, handles, and controls for master, gain, presence, treble, bass and FAC — but no middle control or standby switch. It delivers rich overdrive and vibrant clean tones at volume, but cannot be used quietly without compromising tone or risking tube stress.
