Bedrock Amplification was an American boutique amp builder active in the late 1980s and 1990s, producing hand-wired tube amplifiers with a focus on classic American tones. The 600 was their flagship model offering clean and driven channels with warm 6L6 character. Bedrock amps are collected as early examples of the American boutique movement that emerged as a reaction to the dominance of mass-produced instruments.
