The Mesa Boogie 12AT7 Preamp Tube is a classic 12AT7 - also called ECC81 in Europe - and the tamer brother of the famous 12AX7. The double triode with gentle gain is used for its qualities in classic vintage amplifier circuits and produces a clear headroom with a wide dynamic range. The 12AT7 is also commonly used in analog reverb units such as the Mesa Boogie Mark I.
