Gibson GA-300RVT - Channel 1 preset

Close · 76/100 confidence. Most values readable. Minor gaps filled by inference from similar circuits.

The Gibson GA-300RVT is a high-powered combo amplifier featuring reverb and tremolo in a 100-watt, four-6L6 configuration — among the most ambitious amplifier designs Gibson ever produced. Aimed at professional touring musicians who needed maximum clean volume with studio-quality effects, the GA-300RVT delivers tremendous headroom and a wide, authoritative American clean tone. The spring reverb and tremolo circuits are voiced to complement the powerful output section without being overwhelmed by it, making this one of the most capable American production amplifiers of the 1960s.
