Tung-Sol 12AX7 Preamp Tube
Tungsol 12AX7 Preamp Tube. This re-creation of the original, cherished Tungsol preamp tube, gets rave reviews (including mine on this site). Tungsol 12AX7 tubes are fat sounding tubes with plenty of headroom so they will clean up nicely at lower volume settings on the guitar. This preamp tube exhibits great harmonic content.
