Page 22 shows the Gibson Vanguard and Apollo Amplifiers, and GA-4RE Reverb Echo Unit. The GA-77 Vanguard was available in two speaker cone variations: the Vanguard GA-77 RET, with two 10" speakers, or GA-77RET-L with a single 15" Lansing (JBL) speaker. The Vanguard had been redesigned since its appearance in the previous 1964 Crestline amplifiers catalog; at that time it had model code GA-77 RVT / GA-77 RVTL with a 15" speaker as standard. The Apollo, or Gibson GA-95 RVT was a new model, fitted with two 12" speakers. It was first shown in this catalog, and only included in Gibson price lists from June 1965.
Multiple speaker combinations with special input crossover networks, single speaker construction for smaller rooms or special uses, tone chamber design with ported case construction all provide optimum performance from every amplifier.
These were well-equipped high quality amplifiers, as the price would attest.
Gibson amplifiers provide power, range and depth never before possible in musical instrument application. Gibson quality and dependability is clearly evident throughout the broad spectrum of these amplifiers. A new world of sound is possible with extraordinary performance for every type of amplified instrument.
Exclusive Gibson Spectrum Tone Controls allow precise settings, perfect control of travel, mid range and base. Each function entirely independent of the other. Set treble or bass without disturbing mid range balance. Increase highs or lows, independence sleeve of each other.
These amps were listed in April 1966, (zone 1) at the following prices: Vanguard GA-77 RET-L $620; Vanguard GA-77 RET $500; Apollo GA-95 RVT $469.50; GA-4RE reverb-echo unit $169.50
