Mesa/Boogie premium-grade, lower-gain preamp tube.

The Mesa/Boogie 12AT7 is a premium-grade, lower-gain preamp tube most often used in reverb stages and/or phase inverter positions in older amplifiers. It is used in older Mesa/Boogie designs (Mesa amps built before 1991) as a reverb driver stage, but the 12AT7 can also be substituted in 12AX7 gain stages where users are seeking lower-gain response from higher-gain positions in the preamp string. The lower-gain output of 12AT7s can expand the range of clip and overdrive potential of higher-gain amps for truly authentic roots and traditional styles.

For a preamp tube producing a wide range of tones, order today.
