Here's what you get!
Mesa/Boogie 6L6 STR 445 Power Tubes - Matched Duet
Sells separately for $91.00 eachWith their tightly articulate low-end response, balanced mids, and bright-yet-smooth top end, it's no wonder that you'll find Mesa/Boogie 6L6 STR 445 Power Tubes driving their modern Dual Rectifier and Triple Rectifier tube amplifier heads. This matched pair of tubes can also be used as an update for older Rectifier heads, or as a sonic upgrade for any 6L6-driven tube amplifier.
Mesa/Boogie 5U4GB Rectifier Tube
Sells separately for $39.00 eachYou'll find the MESA 5U4GB inside all the new Mesa/Boogie tube amplifiers. As M/B puts it, it's their "factory favorite" — and for good reason. The MESA 584GB is based on 1950s tube technology, and is essentially an improvement on the 5U4 design. Not only is the tube more reliable, but it's much more compact. In fact, it's about the size of a 6L6 power tube, so take caution when you're positioning it inside your amplifier. What you'll get is a traditional "vintage sag" with an elastic and compressed feel — very cool, MESA 5U84GB.
Mesa/Boogie 12AX7 Preamp Tube
Sells separately for $26.00 eachThe 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.
