MESA/Boogie

Innovative Vacuum Tube Guitar & Bass Amplifiers since 1969

[MESA/Boogie @MesaBoogie]

Your 90s Dual Rec ships with four 6L6 power tubes. Flip the BIAS SELECT switch on the rear panel and you can run a quartet of EL34s instead. 6L6's keep the lows rich & tight. EL34s trim the bottom, push a brighter, more layered shimmer up top, & lean into that British character.

Before MESA built anything, Randall Smith was repairing amps and falling hard for 1950s Tweed circuits.

Fifty years later, the California Tweed continues to build on where the whole story started: one channel of pure 6V6 sound and nothing you don't need.

The Dual Rec rewired heavy guitar in the early '90s. The Badlander is what that lineage sounds like with EL34s in it. The low end gets tighter, the midrange gets more aggressive, and heavy arrives in its own more percussive way.

The BOLD/SPONGY switch on your 90s Dual & Triple Recto is a built-in Variac:
BOLD = full voltage, max headroom, tight punchy attack - clean and percussive rhythm
SPONGY = reduced voltage, sag, scooped mids, elastic feel - sustaining chords and fluid leads

By the late '80s, Doug could hear the shift. The American voice was fading and players were chasing modified British gain. One night, from a hotel room, he called Randy: "We've got to do something different." From that one call, a whole era of heavy music ran on that decision.

"Tight, low end", thats what Mark Morton wants from his amp and thats why he chose the Badlander.

The Mark Five: 35's Channel 1 MID knob changes function at 5. Above that, it's an adjustable gain boost. Crank it, kick on CRUNCH, drop to 10W. You're now grinding in the "clean" channel.

Forty-three years inside MESA/Boogie gives a perspective you can't find without time.

Our Tone Lab Director, Doug West, tells the story in Chapter 1 of our new series "What Makes a Boogie."

@DougDoppler runs the Subway+ Bass DI-Preamp II into a Genzler 4 On The Floor Classic Bass Overdrive. It holds its own and stacks clean with what you've already got.

When you think of your amp, do you hear watermelons too? Mark Morton explains how the sound of a good amp sounds like a good watermelon.

Mark Morton's relationship with Mesa began with a search for new tubes, but not just any tube would do, Mark could hear the difference and knew what he wanted.

Muddy bass tone? Boost a sweepable mid, sweep the frequency knob until the mud gets louder, then flip from boost to cut. The Subway Bass DI-Preamp II sweeps on both Low-Mid and High-Mid bands.

@DougDoppler here showing us how cut through the mix!

90s Dual Rectifier Custom Config in Black Snakeskin over Racing Red. Limited run. 100 watts, two channels, the circuit you know and love.

The amp that scored the heaviest decade in guitar, in one of our loudest finishes ever.

Per-Channel Power Select is the real Mark VII move.

Clean at 90W, Crunch at 45W, Lead at 25W: three footswitchable sounds, three power section personalities.

Three rigs in one chassis.

The Mark Five: 35 has 3 Modes and (at least) three rock voices on Channel 2: MK IIC+, MK IV, XTREME. One rule across all of them: as gain goes up, the BASS knob comes down. Need chunk lows? Pull them from the 80 and 240 sliders.

[MESA/Boogie @MesaBoogie]

The Badlander takes the Rectifier foundation and reworks it with tighter low end, more aggressive midrange, and three gain modes per channel. Both channels are identical, which means you configure the amp around how you play - not how the amp plays.

Whenever Mark Morton shows up, you put a mic on him, and ask him everything you can. In Mark's most recent visit, he talked us through his Mesa history, the tones you get from a watermelon, and how he still plays real amps.

The 25W Class A Triode on the Mark VII gives the sweetest transition to clip, a rounder top end, and its easier to push the power section. Its still plenty loud since the transformers and voltages are built for 90W. 25W moves power section character lower in the volume range.
