The Gibson GA-15RVT adds reverb and tremolo to the 15-watt 6V6-powered platform, making it one of the most feature-complete small combo amps in the GA lineup. Built during the early-to-mid 1960s when reverb and tremolo had become standard expectations for American combo amps, the GA-15RVT's warm, round clean tone is enhanced by lush spring reverb and smooth tremolo. This combination of modest power, excellent tone, and onboard effects makes the GA-15RVT one of the most versatile and desirable amplifiers in the Gibson catalog.
