A premium, high grade preamp tube

Out of stock


These are unused old stock with original packaging. 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.

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

    Wow, great sounding preamp tubes. Placed another order to outfit my Peavey Bravo amplifier with these I am sure they will kick out the hi gain tones.

    I have always read about Mesa Engineering Tube amps and their tube selection process. Now I have the chance to test them out and see if they deliver. So far so good for great rockin clean and overdrive tones.
