"Blonde" aficionados feel this circuit has superior tonal characteristics when overdriven, to the AB763 circuit. The circuit was used from 1960 until July 1963 when the "AB763" circuit was introduced. The 6G(n) ("brownface") circuit was used in several Fender amplifiers, including the Bandmaster. Phase inverter changed to cathodyne (concertina) type. Negative feedback and filter choke added, and the output section given fixed (grid) rather than cathode bias. the 6SC7, to nine-pin mini-tubes of the 12A(n)7 family, as well as the introduction of the floating-paraphase inverter. The D-series circuits represented Fender's shift from octal preamp tubes, e.g. Like the other larger Fender amps, the Bandmaster used cathode-biased 6L6G output tubes, a 6SC7 paraphase inverter, and two more 6SC7s in the preamp with a 5U4 rectifier.
#FENDER BANDMASTER VM PRO#
The first Bandmaster was in all respects almost identical to the Fender Pro, a dual-6L6 26-watt amp with a 1x15 speaker, with one difference: separate treble and bass controls, where the Pro like all other Fender amps to that time only had a single "Tone" knob. Transition models had this period features with smooth blonde tolex covering/sparkle gold grille
