CLASSIC EL34 CHARACTER
The EL34 has long been associated with some of the most recognizable British-inspired guitar tones ever created.
The MESA STR-447 captures that familiar personality with an urgent, aggressive response that works especially well when an amplifier is pushed into overdrive.
Expect a focused bottom end, muscular midrange presence, and articulate highs that allow the guitar to cut through a dense band mix.
MATCHED FOR PERFORMANCE
Power tubes work together as part of your amplifier's output section, which makes proper matching important.
MESA supplies these STR-447s as a matched duet, helping provide consistent operation and balanced performance when replacing a pair of power tubes in a compatible amplifier.
For MESA amplifiers designed around the company's fixed-bias system, using properly selected MESA tubes also removes much of the uncertainty involved in choosing replacement power tubes.
BUILT FOR GAIN
The STR-447 is particularly well suited to players who want an amplifier to feel immediate and aggressive.
Classic Rock.
Hard Rock.
Alternative.
Progressive.
Metal.
High Gain.
The combination of focused lows, pronounced midrange crunch, and articulate highs makes the STR-447 an excellent choice when definition and authority matter.
IMPORTANT COMPATIBILITY NOTE
Not every tube amplifier designed for 6L6 tubes can automatically accept EL34s.
Some MESA amplifiers feature an EL34/6L6 Bias Select switch, while others have specific requirements regarding which tube types and socket positions can be used.
Always consult your amplifier's owner's manual before changing power-tube types.
If you're unsure, Northeast Music Center can help determine whether the STR-447 is appropriate for your particular MESA amplifier.
WHY BUY FROM NORTHEAST MUSIC CENTER?
Replacement tubes are one area where buying the correct product matters.
At Northeast Music Center, we'll help you determine the correct power-tube type and quantity for your amplifier rather than simply selling you a pair of tubes.
Whether you're performing routine maintenance, replacing worn power tubes, or exploring an approved alternative tube configuration, Northeast Music Center can help you keep your MESA/Boogie performing the way it should.
