The Express™ Amplifiers
from Mesa Engineering

NOW ARRIVING! The Express Line to Tone!
Take the 5:25, running EL-84’s out of London straight to the studio for the ultimate big sounding, little amp. Or, catch the 5:50 running 6L6’s out of Fullerton, heading uptown to the gig. These new amplifiers are the direct line to Tone City.

Both 25 and 50- watt models feature four inspiring modes from two opposite personalities spread across two fully independent channels. If Dr. Jeckyll and Mr. Hyde had to share one platform, this would be it.

Say you’re a traditionalist: Select Clean and Blues for your two footswitchable sounds. Or, if you’re addicted to Gain, choose Crunch and Burn. Then stand back as the well-mannered soul of Dr. Jeckyll morphs into the maniacal Mr. Hyde, hardcore beast. Most important is the classic authenticity of all these iconic tones. No matter what your stylistic destination, the Express will take you there… Fast.

Up front, that number “5” indicates the low power, single-ended magic of pure Class A. The “25” and “50” refer to the rated push-pull output. Together, these make up Duo-Class™ our patented new power circuit, the first to offer both single-ended and push-pull configurations in the same amplifier.

But even that’s not the last stop. Each channel is further equipped with its own Contour depth control for added shaping that’s both assignable and footswitchable. Used subtly, Contour adds a halo of depth and chime to gleaming clean sounds. Higher Contour settings, especially in Crunch and Burn, take you into Recto™ turf, tight, huge and menacing.

Don’t be fooled by their compact size! You’ll be shocked when you hear this little monster! And for truly stunning performance, take the 5:50. The1x12 pulls like a freight train, locomotive torque.

So step on up. The Express Line to Tone is now Arriving!

Mesa Express Mode Switche

MODE SWITCHES:
Two Incredible Channels, Four Fully Evolved Modes give you a boarding pass to all the classic guitar styles. The pristine, blooming CLEAN and tight, grinding CRUNCH cover the rhythm territories in Channel 1 while Channel 2 roams the wide open spaces of soloing with howling BLUES and soaring BURN modes.
Mesa Express Contour Controls

CONTOUR Controls
Both Channels feature Assignable / Footswitchable CONTOUR controls that pack the sonic power of a multi-band EQ into one simple control. Blend this dynamic, bouncy circuit with the musically rich TONE controls for a sound far bigger than you’ve ever heard from a combo.
Mesa Express External Jacks

External Switch Jacks

Switch “tracks” remotely with the EXTERNAL SWITCH jacks where CHANNELS, REVERB and the CONTOUR controls can be patched to an external master switching system for remote access. The transparent series EFFECTS LOOP handles the interface to all outboard processing.
Mesa Express Duo Class switchPatented Duo-Class™ Power Switching let’s you switch the Class (operating class) and Configuration (wiring style) in tandem, giving you two dialed power-voice ranges with the flick of a switch.
