The ECC83, or 12AX7 according to US nomenclature, is without question not only the most common but also the most popular tube among guitarists. After all, the double triode is used in most amplifier preamps and is largely responsible for the unique warm distortion character of the amplifier. The EVH ECC83/12AX7 Tubes Duet offers two matched 12AX7 tubes with enormous gain reserves, making them ideal for high-gain amps and particularly insensitive to ambient noise thanks to their absolute resistance to microphoning.
