Jet City Amplification RetroValve Amber

RetroValves are 100% analog vacuum tube replacement devices offering the warm, fat, punchy sound traditionally associated with only glass vacuum tubes. AMBER RetroValves are nominally the same gain as a standard 12AX7 and perform as you would expect a 12AX7 would. RED RetroValves are very high gain, allowing the preamp to achieve gain characteristics not possible with standard vacuum tubes. BLUE RetroValves are significantly lower gain, effectively "cooling off" the preamp gain.

Choose the tube color that fits your sound best.
