The Express features Mesa’s Duo-Class power switching circuit allows the player to choose between Class A/B at 50 watts or Class A at five watts.
Peter Stroud, musical director and guitarist for Sheryl Crow, PG columnist and tone chaser extraordinaire, shed some light on this subject and put it into terms that are easy to understand: “When the amplifier is in Class A mode, it is being pushed much harder – think of it as the power section on ten, full throttle – providing more break-up, mid-range and sag, which is great for that vintage, bluesy rock vibe. In A/B mode the power section provides
much more headroom, producing tighter low-end sounds and a more prominent top-end.” It’s a great design, and Mesa is well-known for inventing this dual class power section.
The 5:50 offers the player two separate channels, each with two modes and independent EQ. Channel 1 provides Clean and Crunch while Channel 2 provides Blues and Burn. Other features include a tube-driven reverb and separate, foot-switchable Contour knobs for each channel.
