A premium, high grade preamp tube


These are unused old stock with generic tube boxes. The Mesa Boogie MESA 12AX7 is a premium-grade preamplifier tube. It’s designed to provide high gain output with an overall balanced tonal quality. You’ll also find that the MESA 12AX7 is both consistent and reliable in its smooth, balanced tonal response. The MESA 12AX7 is a lively, open, and expressive tube. It has a plate size similar to NOS USA made 12AX7 rather than the very short plates found on many new production tubes.

Great in any brand of amplifier, not just Mesa Boogie.

    Same great Mesa tubes in a plain box. Got another order coming before I even plugged these into my amp. Sweet tubes at a kind price.

    Premium Mesa Preamp tubes sound warm and great clean tones as well as hi gain overdriven ones. Picked up a few more for my Peavey Bravo. Love those tubes.
