The Challenge of Impedance Matching
For decades, multiple amplifier and speaker cabinet selector systems have been available, offering a variety of features and functions. However, none have effectively addressed the critical question: “Is it safe to mismatch the impedance of my prized vintage amps and cabs?”
Vacuum tube guitar amplifiers typically require manual setting of the amplifier output impedance to match the speaker cabinet's impedance. This is essential for proper operation, maintaining tone, and avoiding damage to the output tubes and transformer. Mismatching impedances can lead to tonal alterations and potential damage, especially in sensitive vintage gear.

Why Impedance Matching Matters
Most currently available amplifier/cabinet switching systems suggest that impedance mismatching doesn't matter. At Fryette Amplification, they strongly disagree. Impedance mismatching can significantly impact both the safety and tonal quality of your gear.
