Hand-built all-tube 50W combo amplifier from Express Plus series with uniquely inspiring tone that has become one of Mesa Boogie’s most popular amplifiers. It offers genre-defining sounds, near-limitless versatility, and unbeatable value that others can only imitate. It features several exciting features that take it even closer to the flagship status of the award-winning MARK V. The amplifier is equipped with a 8Ohm Celestion Custom 90 driver and uses super versatile, tone-packed preamp featuring two fully independent Channels, each of which contain two style enhanced modes to choose from when creating the foot-switching preferences. Channel 1 hosts the blooming low-gain sweetness of CLEAN or the snarling mid-gain percussiveness of CRUNCH and covers the rhythm territories. Channel 2 offers a different face to mid-gain with the howling honesty of BLUES or a high-gain adventure through the searing layers of molten harmonics in BURN. Together these two inspiring modes invite years of solo exploration. The amplifier runs two 6L6 octal-base pentodes and features the patented Multi-Watt Channel Assignable power switching. This valuable feature allows user to run the output tubes in his choice of three different wattage ratings per Channel. Each power mode has its own tone-spawning operating class and wiring configuration: choose the full power mode of 50 W for Class AB running in a push-pull configuration for punch, authority and headroom. Or, kick down to 25 W for Class A pentode and a more silky, vintage voice with enhanced clip potential. And for the ultimate in low wattage power, knock it down to the 5 W mode which means running one tube in Class A triode wired in a single-ended configuration. The amplifier’s rich all-tube Reverb enhances the spatial quality and each Channel provides an independent Reverb Mix control. The Reverb effect can be triggered on and off via the included footswitch. The amplifier features a dramatic enhancement in the EQ department with the inclusion of the time-honoured 5-band Graphic EQ – the sliders are added in addition to the original Channel Assignable PRESET contour controls and user can now choose whether he wants to use the Sliders or the PRESET in each Channel with the EQ Assign mini toggle. The EQ, whether set to call up the Sliders or the PRESET controls, is also foot-switchable and can be called up at any time via the Express Plus Footswitch. Outboard processing is handled by the series Effects Loop, keeping patching to a minimum and protecting tonal integrity a priority. This amplifier is compatible with most good quality processors and using this feature for all of the rack-type effects will produce gratifying results. Dimensions: 495 x 581 x 298.5 mm.
